Abstract

The invention discloses a casting and salvaging test-free measuring and regulation instrument. The casting and salvaging test-free measuring and regulation instrument comprises a measuring skeleton, and a flow measuring device, a signal processing device, a motor, a supporting and locating device and a regulation device are sequentially arranged on the measuring skeleton from top to bottom; a driving device used for driving the supporting and locating device to be opened or closed and driving the regulation device to operate is further arranged between the motor and the supporting and locating device; and the motor is connected with the supporting and locating device and the regulation device through the driving device. According to the casting and salvaging test-free measuring and regulation instrument, a novel cam arm opening and collecting structure is adopted, the technical problem that in the prior art, visual operation, quantitative fine water injection and depth calibration of a concentric measuring and regulation downhole instrument cannot be achieved is solved, and operation time is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of petroleum stratified water injection, and relates to a testing, measuring and adjusting instrument without throwing and fishing. Background technique [0002] In recent years, due to the difficulties in the plugging and docking of downhole instruments in the conventional eccentric layered water injection process, the measurement and adjustment work cannot be carried out smoothly. The nozzle can be operated at one time to avoid repeated fishing and realize real-time adjustment of the flow rate of each layer. The adjustment period is greatly shortened and the efficiency is improved. [0003] At present, the dispensing process based on the principle of concentricity can only realize the single-layer flow rate test by the decreasing method, and cannot realize the single-layer direct test. This method can guarantee a certain test accuracy for water injection wells with a large single-layer injection volume, ...
