Multipurpose ultrahigh-pressure packer tester

Abstract

The invention discloses a multipurpose ultrahigh-pressure packer tester, which comprises a ultrahigh pressure barrel, a lower sealing structure, a upper sealing structure, a test auxiliary member and a heating jacket, wherein the lower and upper sealing structures are respectively arranged at the lower end and the upper end of the ultrahigh pressure barrel; the test auxiliary member is arranged in the ultrahigh pressure barrel; the heating jacket is arranged on the outer wall of the ultrahigh pressure barrel; the ultrahigh pressure barrel provides a high-temperature and high-pressure testing space; the lower sealing structure is convenient to disassemble, dispose sewage from the barrel and mount a temperature testing component; the upper sealing structure comprises two types, namely a compressed type or an expanding type which are respectively matched with a compressed type or an expanding type packer component to complete the test action, so as to ensure the sealing of the ultrahigh-pressure barrel; the reducing thimble assembly of the test auxiliary member is suitable for the sealing assembly of different sizes to complete the test in the high-temperature and high pressure space; and the heating jacket realizes the full heat exchange between the cold and thermal mediums and the medium in the barrel. In the invention, by using a single ultrahigh-pressure barrel, the high temperature and high pressure test of the compressed type and expanding type packer components of different sizes can be effectively realized in the same container.

Description

technical field [0001] The invention relates to an underground high temperature and high pressure environment simulation test device for oil and gas wells, in particular to a multipurpose ultra-high pressure packer test device. Background technique [0002] In the production process of oil and gas, downhole tools must be able to withstand the harsh environment of high temperature, high pressure, and poor working conditions. Otherwise, once a problem occurs, the oil and gas well will be damaged or even scrapped, resulting in huge losses. For this reason, it is necessary for researchers to design some full-scale and high-performance detection devices on the ground to provide experimental conditions for process research, optimal design, and product inspection of layered oil and gas wells. Before downhole tubing strings and tools go downhole, multi-parameter and high-precision testing can be carried out to grasp their mechanical properties and process properties. Through continu...

Problems solved by technology

If you want to research and develop new specifications and new types of packers, you need to rebuild a special test device. Not only the construction cost is high, but also the construction period is long, which is far from meeting the needs of the rapid development of deep mining and layering operations in today's oil and gas fields.

Researchers have been working hard to design a device that can simultaneously adapt to packers of various sizes for multi-parameter performance tests such as downhole pressure and temperature, but so far have not achieved ideal results
