Abstract
The invention relates to a subdivision testing and regulating instrument for a down hole synchronous test. The subdivision testing and regulating instrument comprises an upper testing and regulating mechanism, a multifunctional segmental locating assembly and a lower guide tester. The multifunctional segmental locating assembly and the lower guide tester are arranged at the lower end of the upper testing and regulating mechanism. Through the subdivision testing and regulating instrument, the problem that multilayer flow cannot subjected to on-line testing during subdivision water injection of a plurality of thin interlayers is solved, the test accuracy rate is increased, and the regulating efficiency is improved. A motor bin receives a regulating order given by a ground control system, a motor rotates forwards (reversely), thus water nozzles arranged in two layers of adjustable stoppers in a seal assembly tool are adjusted to be smaller or adjusted to be larger, and an upper direct-reading type flowmeter and a lower direct-reading type flowmeter of the down hole subdivision testing and regulating instrument measure the flow of two layers. The flow of the two layers and other parameters can be transmitted to the ground control system in real time, an operator can give a regulating order according to injection quantity, and operation is simple and visual. The flow of the two layers is measured and regulated synchronously, the testing and regulating efficiency is improved, the layered flow accuracy rate is increased, and the need of practical application can be met very well.
