Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention is a kind of external pressure working condition simulation test device of drilling equipment, such as figure 1 As shown, it includes a compensation cylinder 2 and a hydraulic system 4. The compensation cylinder 2 is respectively connected to a constant pressure control system 1 and a closed pressure vessel 5. The closed pressure vessel 5 is also connected to a booster system 3. The booster system boosts the engine pressure. system.

[0018] The compensation liquid cylinder 2 is a piston type liquid cylinder, and the compensation liquid cylinder has three connection ports, the three connection ports are A port 2-1, B port 2-2 and C port 2-3, A port 2-1 and C port Ports 2-3 are respectively close to the two ends of the piston rod of compensation liquid cylinder 2, and port B 2-2 is close to the middle of the pisto...

Abstract

The invention discloses a simulation test device for external pressure working conditions of drilling and production equipment, which includes a compensation liquid cylinder and a hydraulic system. The compensation liquid cylinder is respectively connected with a constant pressure control system and a closed pressure vessel, and the closed pressure vessel is also connected with a booster system. . The invention is practical and economical, and solves the problem of pressure fluctuations caused by changes in structural volume or water absorption or drainage of materials during the external pressure test of deep-water oil drilling and production equipment, and can accurately compensate or balance the pressure in the airtight pressure vessel. The stress condition of deepwater equipment is simulated, and the test data can provide a basis for the development and application of deepwater equipment.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling and production equipment, and relates to a simulation test device for external pressure working conditions of drilling and production equipment. Background technique [0002] The working environment of offshore oil drilling and production equipment is harsh, and it bears huge external deep water pressure and internal wellhead pressure. Its safety, reliability, and stability are directly related to the success or failure of oil and gas extraction and environmental pollution. Strict simulation tests and detailed test data analysis are carried out on mining equipment. [0003] In order to simulate various performance and function tests of underwater drilling and production equipment in deep water and high pressure environment, it is usually placed in a closed container, an external pressure of considerable water depth is applied, and various tests and researches are carried out under this ...
