China Petroleum Network News November 20th, the author was informed that the logging company North China division C4645 task team completed the west east gas transmission complex key test well JK1X well sonar logging task, the data quality rate of 100%, marking China's complex salt hole sonar logging breakthrough progress. 　　JK1X well is a key complex dissolved cavity test well in Jintan gas storage of West to East Gas pipeline. Because there is no precedent for cavity filling and cavity expansion, and the effective prediction method of cavity shape is not established, the sonar logging becomes one of the key basis. 　　At the bottom of the cavity of salt soluble complex wells cavity may cause, and technical personnel to develop contingency plans for construction of C4645 operations team, after more than 20 hours of fierce battle, and ultimately complete accurate measurement of the bottom of the cavity shape and volume, provide valuable data for gas storage technology innovation. 　　Relevant content:OGEM petroleum solid control equipment has always been the credibility and quality as the cornerstone of development, in the staff of the full implementation of "unity, innovation, truth-seeking, integrity" business purposes.
