Intelligent injection allocation instrument of water injection well

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: [0001] The invention relates to the technical field of oil production engineering in oil fields, and belongs to an intelligent dispensing instrument for water injection wells. Background technique: [0002] At present, in the testing process where the test instrument is the main body, during the conventional string operation, the dead mouth is preset in the eccentric water distributor and goes downhole to complete the setting of the packer. After the setting is completed, the dead mouth is removed, and then each layer The seal inspection and subsequent flow or pressure test can be carried out after the adjustable plugs are put into the water injection respectively. With the increase of water injection wells, the test workload will also increase significantly, and the existing team can no longer meet the requirements. This technology can modify the injection plan for the automatic control system of the downhole intelligent injection test device, realize the f...

[0002] At present, in the testing process where the test instrument is the main body, during the conventional string operation, the dead mouth is preset in the eccentric water distributor and goes downhole to complete the setting of the packer. After the setting is completed, the dead mouth is removed, and then each layer The seal inspection and the subsequent flow or pressure test can be carried out after the adjustable plugs are used for water injection. With the increase of water injection wells, the test workload will also increase significantly, and the existing team can no longer meet the requirements.
