Visualized test device for trafficability of operation tool string in inclined shaft

Abstract

The invention provides a visualized test device for trafficability of a rope operation tool string, relates to the technical field of oil exploitation test devices, and can simulate trafficability tests of various tool string combinations under the conditions of different oil pipe sizes, different well deviation and azimuth angles and different shaft environments. Test data is provided for optimization and combination of the rope operation tool string in an on-site inclined well section. The visualized test device for trafficability of the rope operation tool string comprises a fixing frame (1), a vertical transparent pipe (2), a connector I (3), a transparent hose (4), a horizontal transparent pipe (5), a second connector II (6), adjusting oil cylinders (7), a middle pulley (8), a guy rope (9), a top pulley support (10), a top pulley (11) and a winch (12). The visualized test device for trafficability of the rope operation tool string is simple in structure and low in manufacturing cost, various oil pipe sizes can be replaced, well deviation and azimuth angles can be adjusted at any time, various wellbore environments can be simulated, test means are provided for newly-developed rope operation tools, and a basis is provided for on-site operation tool selection.

Description

technical field [0001] The invention relates to the technical field of oil exploitation test devices, in particular to a visual test device for the passability of a rope working tool string. Background technique [0002] Wireline operation technology is an important part of oil and gas field development process technology, which can be used for well logging and well testing; downhole tool or device placement, operation and recovery; downhole salvage and other operations. Widely used in well completion, well workover and oil and gas field production operations; wireline operations can not only independently complete various downhole operation tasks, but also integrate into other related operations to provide them with downhole operation services. Ropeline operations require special tools to be lowered into wells using cables to perform specific tasks. A rope access tool string is an essential tool for practicing craft techniques.

Problems solved by technology

[0004] When performing wireline operations in horizontal wells, affected by the inner diameter of the tubing, well inclination, and the length and outer diameter of the tool string, it is often difficult for the wireline tool string to lower the tool to the designed position through the highly deviated well section, which greatly limits the wireline operation Application of technology in horizontal wells and highly deviated wells

[0005] At present, there is no passability experimental device in the industry that can simulate the combination of multiple tool strings in different tubing sizes, different well inclinations and azimuth angles, and different wellbore environments. Combination provides experimental basis
