Pressure booster and pressure test system

Abstract

The present invention provides a booster device and a pressure test system, wherein the booster device includes: a cylinder liner assembly, the cylinder liner assembly has a pressure test through cavity, and the pressure test through cavity includes a low pressure cavity section, an installation cavity section and The high-pressure chamber section, wherein, the cross-sectional area of ​​the installation chamber section is larger than the cross-sectional area of ​​the low-pressure chamber section and the high-pressure chamber section, and the cross-sectional area of ​​the low-pressure chamber section is larger than the cross-sectional area of ​​the high-pressure chamber section; the transmission piston is slidably Set in the pressure test chamber and separate the pressure test chamber, a part of the transmission piston is located in the installation chamber section, and the other part of the transmission piston extends into the high pressure chamber section, so that the second part of the transmission piston faces the low pressure chamber section The area of ​​the first transmission surface is larger than the area of ​​the second transmission surface on the side of the transmission piston facing away from the low-pressure chamber section. The invention solves the problem that the output pressure of the pressing equipment in the prior art is limited and cannot meet the high pressure requirements of the pressure test, resulting in the problem that the pressure test cannot be carried out normally.

Description

technical field [0001] The invention relates to the field of high-pressure pressure testing equipment for oil field downhole tools, in particular to a booster device and a pressure testing system. Background technique [0002] Oilfield downhole tools need to undergo indoor pressure test before official use to ensure their reliability in later work. Existing methods for indoor pressure testing of oil field downhole tools usually use electric booster pumps or pneumatic booster pumps for pressure. Restricted by the level of the above-mentioned pressure equipment, when the test pressure required by downhole tools in the oil field is high, the above-mentioned pressure equipment cannot meet the requirements of the pressure test, resulting in the failure of the normal pressure test. Contents of the invention [0003] The main purpose of the present invention is to provide a booster device and a pressure test system to solve the problem that the output pressure of the pressure eq...
