摘　　要：缅甸某区块探井气层埋藏浅、渗透率低,为缩短测试时间,降低测试作业成本,避免作业过程中的储层污染,将LPR-N测试阀、TST试压阀和气举阀有机组合,通过在管柱结构中加入射孔丢枪装置、倒置安装伸缩接头、3只伸缩接头组合使用、设计射孔枪点火头点火压力大于LPR-N测试阀的开启压力等措施,实现一趟管柱完成试压、射孔、负压诱喷、压裂、气举和测试等功能,井下管柱坐封后不动管柱完成多项作业。经3个层位现场应用表明,施工成功率100%,测试数据完整、准确,可对渤海及海外类似油(气)藏测试提供技术借鉴。The gas reservoirs of exploration well in a block in Myanmar are shallow and have low permeability.In order to shorten the test time,reduce the cost of test operations,and avoid reservoir pollution,this paper realized the combination of LPR-N test valve,TST pressure test valve and gas lift valve.In addition,through some measures,such as adding a perforating gun device in the column structure,using inverted installing expansion joint,combination use of three expansion joints,and controlling the ignition pressure of the perforating gun to be greater than the opening pressure of the LPR-N test valve.Etc.,to achieve the pressure test,perforation,negative pressure induced flow,fracturing,gas lift and test and other functionsin one trip of the string.When the downhole string is set,multiple operations can be completed without moving the column.The field application of 3 layers shows that the construction success rate is 100%,the test data is complete and accurate,and it can provide technical reference for testing the similar oil(gas)reservoirs in Bohai and overseas.
