Problems solved by technology

[0002] At present, in the testing process with testing instruments as the main body, with the increase of water injection wells, the testing workload has also increased significantly, and the existing team has been unable to meet the requirements.
The pass rate of water injection is affected by many factors such as formation pressure and inter-well connection, and the situation is complicated and changes rapidly. Shortening the deployment cycle can only improve the pass rate of water injection to a certain extent, and will double the test workload

Abstract

The invention relates to the oil field oil production engineering technology field, and belongs to an intelligent injection allocation testing device of a water injection well. The intelligent injection allocation testing device of the water injection well mainly solves the problems that the existing separated layer water injection equipment has high testing work load, long allocation period and low water injection qualification rate in the construction process. The intelligent injection allocation testing device of the water injection well is composed of an upper joint 1, an upper connecting sleeve 2, a guiding body 3, a non-contact electric energy conversion system 4, a central pipe 5, an automatic control circuit board 6, a main body 7, a diversion body 8, a flow control valve 9, a data collection system 10, a lower connecting sleeve 11 and a lower joint 12, wherein, the non-contact electric energy conversion system 4 is connected with the central pipe 5 in a locating way, and the automatic control circuit board 6 is bonded with the central pipe 5. The device adopts mechanical-electrical integration design, saves a great quantity of conventional production test cost, controls the opening degree of the flow control valve and has the advantage of automatic water distribution.

Description

Technical field: [0001] The invention relates to the technical field of oil field testing, and belongs to an intelligent distribution and testing device for water injection wells. Background technique: [0002] At present, in the testing process with testing instruments as the main body, with the increase of water injection wells, the testing workload has also increased significantly, and the existing team has been unable to meet the requirements. The qualification rate of water injection is affected by many factors such as formation pressure and inter-well connectivity. The situation is complex and changes rapidly. Shortening the deployment cycle can only improve the qualification rate of water injection to a certain extent, and will double the workload of testing. This technology can realize the full automation of water injection measurement and adjustment, shorten the test cycle, reduce the workload, improve the qualified rate of water injection, provide strong technical ...
