海上油气井高昂的测试费用致使压力恢复测试时间短，造成低渗储层试井曲线不完整，无法准确解释储层渗透率。反褶积试井技术通过采用杜哈美叠加原理，将短时间的压力恢复测试段之前的产能测试段压力及生产压力史叠加到短时间的压力恢复测试段压力，由此试井解释段由一个短时间的压力恢复测试转化为一个长时间恒定产量压力降落测试，进而等效于大幅度增加压力恢复测试段的测试时间，从而使低渗油气井试井曲线更完整，能够出现水平径向流，因此能够准确解释储层渗透率，并精确评价储层物性。反褶积试井技术成功应用于海上 M气田和N气田低渗油气井，为低渗油气田的开发调整提供指导。“,”The high cost of offshore oil test and gas well test demands a shorter test time ,making the well-test curve of low permeability reservoir incomplete ,and calculation of the reservoir permeability inaccurate .Through deconvolution testing technique based on Duhamel Superposition Principle ,the production test section and the production pressure history of the test section before the short build -up test are superposed to the short build-up test .A short time build-up test is turned into a long time constant output drawdown test .Therefore ,the radial flow of well test curves can be explained ,and the test time is equivalent to a substantial increase in build -up test .The reservoir per-meability can be accurately interpreted ,and the reservoir physical properties can be evaluated accurately .In order to provide guidance for the development of low permeability oil and gas field ,the successful technique of deconvolution test should be used in the low permeability oil and gas well of M gas field and N oil field .
