The invention provides a sealing testing device for a packer. The sealing testing device comprises a liquid pressure testing pump, a bubble detector, a gas pressure testing pump, a heating control system and a tension and compression testing machine; wherein the liquid pressure testing pump, the tension-compression testing machine and the heating control system are connected with the testing prototype, and the gas pressure test pump and the bubble detector are respectively connected with two ends of a rubber sleeve on the test sample machine. The gas pressure test pump is connected with the driving gas source and the pressurizing gas source, and the liquid pressure test pump is connected with the heat conduction oil source. The invention further provides a sealing test method for the packer. According to the sealing test device and method for the packer, the international highest standard detection requirement of the packer can be met, the gas sealing capacity of the packer at the topof the tail pipe in the high-temperature and high-pressure environment can be detected, and therefore the use safety of the packer in a high-temperature and high-pressure gas well is guaranteed.
Description
technical field [0001] The invention relates to the technical field of oil and gas well cementing and completion, in particular to a sealing test device and method for a packer. Background technique [0002] In recent years, as the global exploration and development technology continues to challenge the exploration direction of deep layer and deep water, the reservoir environment of high temperature and high pressure and the requirements for safe development of oilfields have been continuously improved, and the quality of cementing and the safety and reliability of cementing tools have been raised. higher requirements. In order to meet the needs of high temperature and high pressure oil and gas wells and solve technical problems in field use, the reliability of tools can be improved by adding a liner top packer, thereby reducing the occurrence of risks. However, the performance of the packer and its applicability to high-temperature and high-pressure environments have becom...
