Abstract

The invention relates to the technical field of oil production engineering, and belongs to a gas well storage type integrated layered production allocation pressure gauge, which solves the problem in the prior art that long-term pressure monitoring and productivity allocation during a dynamic production process of two gas producing zones cannot be realized at the same time. The gas well storage type integrated layering and production allocating pressure gauge is formed by a salvaging connector (1), a positioning main body (2), anti-rotation pins (3), positioning scissors (4), torsion springs (5), scissor pins (6), regulating sleeves (7), a pressing cap (8), an air faucet (9), regulating rings (10), sealing packings (11), pressing rings (12), a production allocation main body (13), a sensor (14), a back-up nut (15) and a pressure gauge cabin (16). The gas well storage type integrated layered production allocation pressure gauge disclosed by the invention has the advantages that the structure is simple and reliable, static and dynamic production of two kinds of gas producing zones and long-term monitoring on pressure in a shaft can be realized at the same time, and the like.

Description

technical field [0001] The invention relates to the technical field of oil production engineering, and belongs to a gas well storage-type integrated layered proration pressure measuring instrument. Background technique [0002] At present, the pressure detection equipment in natural gas wells uses a single-channel design, which can only realize the pressure information collection of one production layer, and cannot realize the long-term pressure monitoring and production capacity deployment in the dynamic production process of two production layers at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a gas well storage type integrated layered proration pressure measuring instrument which can simultaneously realize static and dynamic production of two gas producing layers, long-term monitoring of wellbore internal pressure and capacity allocation. [0004] The present invention is realized through the following technical so...
