A safety protection device for downhole tool ultra-high pressure hydraulic test

Abstract

The invention relates to a safety protection device for an ultra-high pressure hydraulic test of downhole tools. The utility model mainly solves the problems that operators need to go up and down the pit frequently, and the downhole tools are frequently lowered into and lifted out of the pit during the hydrostatic test of the existing downhole tool. It is characterized in that: the front and rear sides of the frame box (1) are fixed with a protective cover mechanism (3), the inside of the frame box (1) is fixed with a platform lifting mechanism (4) on the left and right sides, and the platform lifting mechanism ( 4) The upper part is connected with a lifting platform (5), and the left and right sides of the upper part of the frame box (1) are fixed with a safety sliding support mechanism (2) through columns, and the safety sliding support mechanism (2) is located on the lifting platform (5) on both sides. The ultra-high pressure hydrostatic test safety protection device for downhole tools can place the ultrahigh pressure hydrostatic test process of downhole tools in a safe environment, greatly reduces auxiliary operation time, reduces labor intensity of operators, and saves space.

Description

[0001] Technical field: [0002] The invention relates to the field of oil fields, in particular to a safety protection device for ultra-high pressure hydraulic tests of downhole tools. [0003] Background technique: [0004] At present, the test pressure for hydraulic testing of most downhole tools is relatively low, generally not exceeding 30MPa. The hydraulic testing test of such tools can be fixed with ground clamps and carried out under the protection of a simple isolation plate. This type of hydraulic test operation method has high work efficiency, and as long as the operator is far away from the test site, it will not cause danger to the operator. [0005] However, for the ultra-high pressure (about 100MPa) hydraulic pressure detection test of some downhole tools, it is generally carried out in the pit. The operator first installs the downhole tool to be tested; it is transported and lowered to the test pit by a crane; on the premise of ensuring safety, the operator goe...

Problems solved by technology

Working in such a high-pressure test environment requires the staff to frequently go up and down between the ground and the pit to lower and lift the downhole tools into and out of the pit. Therefore, it takes a long time for the auxiliary process of the test. It is also inconvenient for personnel to exchange information, and there are potential safety hazards
