Problems solved by technology

Not only the labor intensity of workers is high, but also the efficiency is low, which restricts the improvement of oilfield productivity
And multi-layer water injection, its workload and difficulty are doubled
Since the fixed faucet cannot be adjusted steplessly, there is still a certain difference between the final deployed flow and the design required flow.

Abstract

The invention discloses a testing and adjusting linkage system. The testing and adjusting linkage system comprises a water distributor (1) and a testing and adjusting device (2) arranged inside the water distributor (1); a guide rail sleeve (4), an upper magnet (6), a lower magnet (8) and an adjustable water nozzle (10) are arranged in the water distributor (1); and a magnetic switch (17), a mechanical locating block (25) and a mechanical claw (38) are arranged in the testing and adjusting device (2), wherein the mechanical locating block (25) is used for locating a locating seat C (52) inside the testing and adjusting device (2) in a matching manner, the mechanical claw (38) is matched with the adjustable water nozzle (10) and can freely adjust the degree of openness of the adjustable water nozzle (10), and thus, the water injection quantity is accurately controlled. The testing and adjusting linkage system has the beneficial effects that the operation is simple and laborsaving and timesaving, the workload is light, the efficiency is high, the accuracy is high, the aims of increasing the testing efficiency, shortening the testing time and increasing the accuracy of test data are reached, the difficulty in operation of oilfield layered water injection is reduced, the working efficiency is increased, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of layered water injection in oilfields, in particular to a measurement and adjustment linkage system and an operating process thereof. Background technique [0002] There are many techniques for oil field layered water injection, including oil and casing layered water injection, single-pipe layered water injection, multi-pipe layered water injection, etc. However, the single-pipe layered water injection string is the most common. In the single-pipe layered water injection, only one pipe string is lowered in the well, and the entire water injection well section is isolated into multiple unconnected intervals by using a packer, and each interval is equipped with a water distributor. Injected water enters the well from the tubing, and is injected into the formation of each interval under the control of the water nozzle on the water distributor of each interval. According to the structure of the water distrib...
