Definitions
- any loss of efficiency can be costly to a well operator.
- a washout of a drill string or a formation while drilling can allow pumped mud to flow at rates other than the flow rates at which an operator believes they are flowing.
- a washout can cause mud to flow to locations other than where the operator desires it to flow. Such conditions can cause issues during drilling due to a lack of mud flowing through the bit, for example. Methods and systems for detecting washouts as soon as they occur are therefore valuable to well operators.
- the method includes, positioning a plurality of sensors along a downhole drillstring, communicatively coupling the plurality of sensors to a processor, and analyzing data sensed by the plurality of sensors with the processor for relationships indicative of a washout.
- a downhole drillstring washout detection system includes, a plurality of sensors positioned downhole along a drillstring for measurement of at least one parameter therewith, a communication medium coupled to the plurality of sensors, and a processor coupled to the communication medium.
- the processor configured to receive data from at least the plurality of sensors, the processor further configured to determine relationships of sensed data indicative that a washout has occurred.
- FIG. 1 depicts a washout detection system disclosed herein applied at a drillstring within a wellbore with a formation washout
- FIG. 2 depicts a washout detection system disclosed herein applied to a drill string with a washout formed therein.
- the washout detection system 10 includes, a plurality of pressure sensors 14 positioned along a drillstring 18, a communication medium 22 coupled to the plurality of pressure sensors 14, and a processor 26 that is also coupled to the communication medium 22.
- the communication medium 22 provides operable communication between the pressure sensors 14 and the processor 26 and can include a wired pipe 28, for example, which permits high bandwidth data transmission there through.
- the processor 26 can be located at surface, as disclosed herein or at some other location along the drillstring 18, such as in a bottom hole assembly 30, for example, while monitoring the pressure sensors 14.
- V x V 1 1
- V x A x V x
- V 2 A 2 V 2 3
- A is the cross sectional flow area
- V is the flow velocity
- A cross sectional area at depth h ,
- Ph pressure at depth h .
- the cross sectional area of the annulus 34 at a given depth is a function of the flow rate and the pressure measured at that depth.
- These formulae are most accurate for idealized conditions that are assumed to be held true during measurements; mud flow is constant, mud density is constant, flow in the annulus 34 is laminar and the mud is incompressible. More sophisticated models may describe the physical behavior even better as disclosed below.
- the washout detection system 10 monitors pressure at the pressure sensors 14 and calculates a corresponding annular area at the depths of each of the pressure sensors 14. In response to the detection system 10 calculating an area greater than a selected value, the washout detection system 10 issues may sound an alert indicating that the washout 54 has occurred.
- FIG. 2 another embodiment of a downhole drillstring washout detection system 110 disclosed herein is illustrated.
- the detection system 10 was directed at detecting washouts in the walls of a wellbore or a wellbore lining
- the detection system 110 is directed to detecting a washout in the wall of a portion of the drillstring 18 itself such as a section of pipe, for example characterized by a hole therethrough through which flow can escape.
- the washout detection system 110 includes, a plurality of sensors 114 positioned along a drillstring 18, a communication medium 22 coupled to the plurality of sensors 114, and a processor 26 that is also coupled to the communication medium 22.
- the communication medium 22 provides operable communication between the sensors 114 and the processor 26 and can include a wired pipe 28, for example, which permits high bandwidth data transmission therethrough.
- the processor 26 can be located at surface, as disclosed herein or at some other location along the drillstring 18, such as in a bottom hole assembly 30, for example, while monitoring the sensors 114.
- points A, B, C and D are located at points A, B, C and D.
- Point A is inside the drillstring 18 at a depth Iu, which may be at surface level
- point B is outside the drillstring 18 at a depth h B , which may be at surface level
- point C is inside the drillstring 18 at a depth he
- point D is outside the drillstring 18 at a depth ho- Note, although illustrated herein points C and D are at the same depth, alternate embodiment may have points C and D at different depths.
- the sensors 114 can be pressure sensors or flow sensors. An embodiment wherein the sensors 114 are pressure sensors will be discussed first.
- PA PA 0 , P B * P B ⁇ > , P c ⁇ P c a , PD ⁇ PD 0
- the processor 26 can, therefore, through observation of a change in pressure sensed by one of the sensors 114, detect that a washout 118 has occurred.
- the processor 26 can issue an alert in response to detection of the washout 118 so that an operator may initiate a response. Additionally, a magnitude of the washout 118 will be related to the change in pressure encountered and, as such, a magnitude of the washout 118 can be approximated therefrom.
- the depth at which the washout 118 occurred can be determined by the location of the one or more sensors 14 for which the pressure readings have changed. Having more sensors 14 with closer spacing therebetween will increase the resolution through which the washout 118 is located.
- the washout detection system 110 can employ sensors 114 that are flow sensors instead of pressure sensors.
- the flow sensors 114 in this embodiment measure volumetric mud flow directly, ⁇ .
- a redirection of flow for example, through the washout 118 in a wall of the drillstring 18, will be detectable by the flow sensors 114 positioned below the washout 118 due to changes in flows sensed thereby.
- flow sensors 114 above the washout will not sense a change in flow.
- the processor 26 With such information the processor 26, by knowing the locations of the flow sensors 114 along the drillstring 18, can determine a location of the washout 118 along the drillstring 18. Additionally, by calculating a change in the flow rate sensed the processor 26 can determine the flow rate through the washout 118 and thus the severity of the washout 118. [0047] While the invention has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims.
