摘　　要：电缆测压取样技术在海上油气勘探评价过程中发挥了重要的作用,针对低孔、低渗、潜山花岗岩等裂缝储层的测压取样的难点,中海油服自主研发的EFDT仪器使用双封隔器模块已在海上多个潜山油气藏的勘探中应用。通过双封隔器测压取样技术的特点、优缺点分析以及渤海地区某井的现场作业实例进行分析总结,对该测压取样技术在现场的进一步推广应用具有指导意义。Wireline formation Pressure test and sampling with pump function technology has played an important role in the process of offshore oil and gas exploration and evaluation.In view of the difficulties in pressure test and sampling on fractured reservoirs such as low porosity,low permeability and buried hill granite,the EFDT instrument independently developed by COSL has been applied in the exploration of several offshore buried hill oil and gas reservoirs with double packer module.In this paper,the characteristics,advantages and disadvantages of the dual packer pressure test and sampling technology and thefield operation example of a well in Bohai bay are analyzed and summarized,which has guiding significance for the further application of the sampling technology in thefield.
