Abstract

The invention provides a cementing tool test device, comprising: a well wall assembly, the well wall assembly is a cylindrical structure with a first cavity; a pipe string assembly, the pipe string assembly is a cylindrical structure with a second cavity, The pipe string assembly is movably arranged in the first chamber, and a packing chamber for filling material is formed between the pipe string assembly and the well wall assembly. The pipe string assembly can be connected with the cementing tool to be tested and sent into the first A cavity. Through the technical solution provided by the invention, the problem of high test cost of cementing tools in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a cementing tool test device. Background technique [0002] At present, the sliding sleeve cementing layered fracturing completion technology is developing rapidly, and there are many types of supporting cementing tools such as cementing sliding sleeves, rubber plugs, pressure relief seats, and cementing dividers, etc., and the structure is updated quickly. This type of product faces a problem in the performance test: since the cementing process on the production site is a one-time irreversible process, the cost of on-site verification is high when the product is validated, and if a problem occurs, it will cause cementing failure, Arai scrapped and other huge losses. Therefore, the cementing tool test in the prior art has the problem of high cost. Contents of the invention [0003] The invention provides a cementing tool testing device to solve the problem of high...
