Abstract

The invention relates to the field of oil and gas pipelines and discloses a process pipe column for a horizontal well fluid producing profile testing technology and a flow monitoring method to solve the technical problem of low horizontal well fluid producing profile testing efficiency in the prior art. The process pipe column comprises a pump, at least two sets of test components and an electric control sliding sleeve, wherein each set of the test components include a straightening device, an electric control separator connected to the straightening device, and a tester connected to the electric control separator; every two of the at least two sets of the test components are connected through a working oil pipe; and a first end of the electric control sliding sleeve is connected to the pump and a second end of the electric control sliding sleeve is connected to the at least two sets of the test components. Through the scheme, all layers can be tested in one time after each layer section of a horizontal well fluid producing profile is segmented through the process pipe column, so that the technical effect of improving the test efficiency is achieved.

Description

technical field [0001] The invention relates to the field of oil and gas pipelines, in particular to a horizontal well liquid production profile testing technology process string and a testing method. Background technique [0002] In recent years, with the development of horizontal well technology, horizontal well development has become an important way to increase single well production, improve development effect and enhance recovery. development becomes reality. At present, the main completion methods for the development of tight oil reservoirs are 51 / 2" casing cementing completion and open hole preset string completion (preset 4 1 / 2" casing, open hole packer and ball fracturing slide The casing cementing well completion adopts the staged fracturing technology of pumping bridge plug and the dragging staged fracturing technology of coiled tubing with bottom seal; After staged fracturing of horizontal wells was put into production, the production of single wells in tight ...
