Application of Straddle Packer in Sampling of Buried Hill Strata in Bohai Oilfield
The buried hill strata oil and gas reservoirs in Bohai oilfield have good oil quality and large reserves,but due to their deep burial depth,complex lithology and diverse reservoir spaces,it is difficult to evaluate the effectiveness of reservoirs and fluid properties during the exploration and development process.The mid drilling oil and gas reservoir tester(EFDT)is a modular,pumped cable formation tester developed by China Oilfield Services Co.,Ltd.The straddle packer sampling technology can successfully seal and sample in highly heterogeneous formations,accurately determine the presence of oil and gas in buried hill formations,provide reliable basis for correctly understanding reservoir characteristics and fluid types,and provide important reference for exploration decisions to determine buried hill reservoir formation patterns.
