摘要
渤海油田潜山地层油气藏油质好、储量大,但由于埋藏深、岩性复杂、储集空间多样,勘探开发过程中储层有效性评价及流体性质评价难度大.钻井中途油气层测试仪(EFDT)是中海油田服务股份有限公司自研的一种模块化、泵抽式电缆地层测试仪,其双封隔器取样技术能够在非均质性强的地层成功坐封和取样,准确判断潜山地层是否存在油气,为正确认识储层特征和流体类型提供可靠依据,为确定潜山成藏模式的勘探决策提供重要参考.
Abstract
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.
