Abstract
The invention relates to the technical field of oil field oil production engineering and belongs to an intelligent injection allocation instrument of a water injection well which mainly solves the problems that the existing layering water injection equipment cannot carry out continuous monitoring to water injection state of all layers under the ground in the construction process, and the test working capacity is high; the intelligent injection allocation instrument of the water injection well is composed of a cable head 1, an electrical connector 2, a non-contact electric energy conversion system 3, a wireless transceiving module 4 and a locating mechanism 5, wherein, the electrical connector 2 is connected with the non-contact electric energy conversion system 3 in a locating way, and the non-contact electric energy conversion system 3 is in threaded connection with the locating mechanism 5 ; the instrument adopts mechanical-electrical integration design, and has the advantages of shortening test period, reducing work load and improving water-injection qualification rate and the like.
Description
Technical field:
The present invention relates to the oil field technical field of oil production engineering, belong to a kind of intelligent injection allocation instrument of water injection well.
Background technology:
Be in the main body test technology at tester at present, in eccentric injection mandrel, preset dead mouthpiece during conventional tubing string operation and finish setting in going into the well packer, set and pull dead mouthpiece out after finishing, and then each layer dropped into adjustable blanking plug respectively carry out to test envelope and follow-up flow or pressure test after the water filling, increase along with water injection well, the test job amount also increases substantially thereupon, and existing troop can't satisfy.This technology can be revised the injection allocation scheme for the automatic control system of downhole intelligent allocation testing device, realize the comprehensive automation of the automatic allocation testing device in down-hole, shorten test period, reduce workload, improve the water filling qualification rate, for oil field steady oil control water provides strong technical support, will produce remarkable economic efficiency and social benefit.
Summary of the invention:
The objective of the invention is to realize a kind of each interval water filling state of down-hole to be carried out continuous monitoring, and make in real time surveying according to monitoring result and transfer response, shorten the intelligent injection allocation instrument of water injection well of test period.
Technical scheme of the present invention is: it is made up of cable head, electric connector, non-contact electric energy converting system, radio receiving transmitting module, detent mechanism; Wherein cable head and electric connector are by being threaded, and electric connector and non-contact electric energy converting system are by being located by connecting, and non-contact electric energy converting system and detent mechanism are by being threaded, and radio receiving transmitting module is fixed in the detent mechanism.
The present invention has following beneficial effect:
Because the present invention adopts Electromechanical Design, can carry out exchanges data with the automatic control system in the downhole intelligent allocation testing device by radio receiving transmitting module, can carry out dynamic monitoring to each characterisitic parameter of down-hole.Not only can avoid a large amount of production tests, also avoid the interference of test simultaneously, save great amount of conventional production test expense ordinary production.Realized the comprehensive automation of the automatic allocation testing device in down-hole, shortened test period, reduced workload, improved the water filling qualification rate,, will produce remarkable economic efficiency and social benefit for oil field steady oil control water provides strong technical support.
