Definitions
- TITLE SYSTEM AND METHOD FOR DETERMINING THE
- This disclosure relates generally to systems, methods and devices for obtaining drilling assemblies that utilize an orientation sensing system.
- Valuable hydrocarbon deposits such as those containing oil and gas, are often found in subterranean formations located thousands of feet below the surface of the Earth.
- a drilling assembly also referred to herein as a "bottomhole assembly” or “BHA”
- BHA bottomhole assembly
- Such a drilling assembly is attached to the downhole end of a tubing or drill string made up of jointed rigid pipe or a flexible tubing coiled on a reel ("coiled tubing").
- the drilling assembly may use a steering unit to direct the drill bit along a desired wellbore trajectory.
- Wellbore drilling systems may also use measurement-while- drilling (MWD) and logging-while-drilling (LWD) devices to determine wellbore parameters and operating conditions during drilling of a well.
- These parameters and conditions may include formation density, gamma radiation, resistivity, acoustic properties, porosity, and so forth.
- Many of these tools are directionally sensitive in that, to be meaningful, the measurements made by these tools should be correlated or indexed with a frame of reference for the formation.
- the angular difference between a reference vector on a tool and a vector of reference is referred to as a toolface angle.
- the reference vector may be borehole highside or magnetic north.
- borehole highside is an uppermost side of a non-vertical borehole. It is commonly desired to present the output from imaging sensors oriented with reference to the borehole highside.
- the measurement of borehole highside may be made using devices such as a three-axis accelerometer positioned on the directionally- sensitive tool.
- a drill string may include two or more directionally sensitive tools. While each such tool may include an orientation sensor, such an arrangement may be expensive and complex.
- a single sensor may be used for a plurality of directionally-sensitive tools if the angular alignment of these tools is known. Because wellbore tools are often assembled using threaded connections, a plurality of directionally- sensitive tools may not be rotationally aligned within acceptable tolerances. That is, for example, due to machining variations, two directionally-sensitive tools that are configured to point in the same direction could have an angular offset.
- the present disclosure is directed to addressing one or more of the above stated drawbacks for determining the orientation of logging tools and other elements of a drilling system.
- the present disclosure provides a rotational alignment system for determining the relative rotational position or angular relationship between two or more elements in a section of a work string conveyed into a wellbore.
- the rotational alignment system includes one or more sensors that detect one or more reference objects positioned on the elements. Based on the measurements made by the sensor, a processor determines the rotational or angular offset between the two or more elements on the drill string.
- rotational offset values are determined for directionally-sensitive sensors in a logging tool. The determined rotational offset values are then used by a surface logging computer to properly correlate data provided by the logging tool.
- the sensor(s) of the rotational alignment system locate and characterize the reference objects by using optical or magnetic images of two or more reference objects positioned on the logging tool.
- the captured images are processed by the processor to determine the angular offsets between the reference objects.
- the determined offsets are then transmitted to and stored at the surface logging computer.
- Figure 1 shows a schematic diagram of a drilling system with a bottom hole assembly according to one embodiment of the present disclosure
- Figure 2 shows a sectional schematic view of a logging tool used in accordance with one embodiment of the present disclosure
- Figure 3 illustrates the relationships of the measured angular offsets in accordance with one embodiment of the present disclosure.

- an orientation sensor 312 may be positioned on another device such as a non-rotating section 202 of a steering device 200.
- the tool faces 303, 305 and 307 all point in different directions.
- the angular offset 0' and 0" of the tool face 305 and 307 relative to the tool face 303 must be known in order to determine the tool face angles of the adjacent modules 304 and 306.
- embodiments of the present disclosure enable the determination of the tool face angle of one or more tool modules adjacent to tool module 302 by first determining the relative angular offset between tool module 302 and the adjacent tool modules. During operation, determined angular offsets are summed with the measured tool face angle ⁇ of tool module 302 to determine the actual tool face angle of the adjacent tool modules 304 and 306.
- determining a tool face angle of one tool module enables the determination of the tool face angle of any tool module fixed to that tool module.
- the drilling system 10 uses a rotational alignment tool 320.

- reference object refers to any element or device that may be detected by the sensor 330.
- the control unit 332 determines one or more rotational offset values and transmits the value(s) to an external device.
- the external device may be a processor 336 configured to operate as a surface logging computer.

- the control unit 322 may include a processor that is programmed to determine the rotational offset values and transmit these values to a surface logging computer.
- the control unit 322 may transmit unprocessed sensor data to the surface logging computer, which is programmed to determine the rotational offset values from the received unprocessed sensor data.
- a number of methodologies may be employed to determine the relative angular relationships of the tool faces of the elements 322, 224 and 326. A few non-limiting examples are described below.
- the senor includes an optical camera that captures images of the elements 322, 324 and 326 as these elements are being conveyed into the wellbore 12.
- the images may be in analog or digital form.
- the control unit 332 analyzes the images to determine the relative angular positions of the reference objects 334, 336, 338. For instance, upon analyzing the captured images, the control unit 332 could determine that reference objects 334 and 336 have a forty degree angular separation and reference objects 334 and 338 have a fifty degree angular separation. Thus, upon determining the tool face of reference object 334, the tool face of reference objects 336 and 338 may be readily calculated.

- the reference objects may be active or passive.
- a passive object may be a discontinuity on an outer surface of the element 322.

- the signal may be an optical, acoustic, electromagnetic or other type of discemable signal.
- the reference object may be integral or formed on the drill string or attached to the drill string. Moreover, the reference object may be a pre-existing feature on the drill string and not necessarily a feature added to the drill string for the sole purpose of determination angular relationships.
- the reference objects may be all the same or have unique identifying characteristic. For instance, the reference object 336 could have a shape or emit a signal that allows unique identification by the control unit 322.
- Suitably configured RFID transponder tags are one non- limiting example of an active reference object.
- the processing performed by the processor 322 may be extensive or minimal depending on the nature of the data received from the sensor.
- the processor 322 may include pre-programmed instructions that analyze the measured data to determine an angular position.
- the sensor may transmit a signal only when there is a predetermined relationship between the sensor 322 and the reference object; e.g., a signal may be transmitted when the sensor 322 is aligned with the reference object. In such an arrangement, analysis of the signal itself is not necessarily required to determine the angular position of the reference object.
- the rotational alignment system 320 may be deployed at a location on the rig where the drill string is being made-up. Also, the rotational alignment system 320 may be configured as portable device. For example, a human operator may carry the sensor 330 and scan a section of a made-up drill string (e.g., a stand). The measurements made by the sensor 330 may be either stored for later retrieval or wirelessly transmitted to the control unit 332, the processor 336 or some other external device.
- the sensor(s) 330 of the rotational alignment system 320 are operated to locate and characterize the reference objects, e.g., reference markers 336 and 338.
- the reference objects e.g., reference markers 336 and 338.
- an optical sensor could capture images of the joints between elements 334 and 336 and elements 336 and 338.
- the captured images are processed by the control unit 332 to determine the angular offsets between markers 334, 336 and 338.
- the determined offsets are then transmitted to and stored at the surface logging computer 336.
- the determined offset may also be transmitted to another device via a communication device 370.
- the determined angular offset value may be transmitted to the BHA processor 44.
- the logging tool 300 measures various parameters of interest relating to the formation.
- the orientation measurement sensor 310 periodically and/or continuously determines the tool face of the tool module 302 relative to highside or other selected reference frame for the tool module 302. Because modules 304 and 306 have a fixed relationship with the module 302, the tool faces of these two modules may also be determined by using the surface-determined angular offset between module 304 and modules 306 and 308.
- the BHA processor 44 uses the determined angular offset value to correlate the measurements of the modules 304 and 306 with borehole highside.
- the surface logging computer 336 at the surface uses the determined angular offset value to correlate the measurements of the modules 304 and 306 with borehole highside.
