Simulation test device of high-temperature high-pressure horizontal well packer

Abstract

The invention discloses a simulation test device of a high-temperature high-pressure horizontal well packer, and belongs to the field of petroleum engineering. The simulation test device comprises a hydraulic circuit system for pumping in high-pressure liquid, a heating incubator and a test sleeve arranged in the heating incubator. The hydraulic circuit system is connected to the heating incubator through an oil pipe. The test sleeve is horizontally arranged on a base in the heating incubator and connected with a packer clamping device through an external thread. The packer clamping device is connected with the packer through an internal thread and fixes the packer in the test sleeve. By means of the simulation test device, the setting test and the examining seal test can be smoothly completed, and the simulation test device has good interchangeability and has the advantages of being good in safety, easy to operate and capable of precisely and widely simulating actual underground working environments.

Description

technical field [0001] The invention belongs to the field of petroleum engineering, and in particular relates to a packer simulation test device for a high-temperature and high-pressure horizontal well, which is used for simulating a high-temperature and high-pressure environment on the ground and performing a performance test of a compression packer. Background technique [0002] A packer is a downhole tool widely used in oil and gas well operations, and its function is to realize delamination operations in oil and gas wells. Its performance directly affects the production and production safety of oil and gas wells. With the development of oil and gas fields, the formation conditions are becoming more and more complex, and layering operations are becoming more and more common. The requirements for the use of packers are also getting higher and higher. The failure of packers often occurs, resulting in the failure of oil and gas production. steady progress.

Problems solved by technology

With the development of oil and gas fields, the formation conditions are becoming more and more complex, and layering operations are becoming more and more common. The requirements for the use of packers are also getting higher and higher. The failure of packers often occurs, resulting in the failure of oil and gas production. steady progress

[0003] In the production process of oil and natural gas, the packer must be able to withstand the harsh environment of high temperature, high pressure, and poor working conditions in the downhole. Otherwise, once a problem occurs, the oil and gas well will be damaged or even scrapped, resulting in huge losses.
