摘　　要：针对水下扇等沉积体高泥质含量低渗复杂岩性储层,以梨树凹油田为研究对象,以测井、岩心分析、试油试采资料为依据,确定复杂岩性储层识别的界限,探索性建立了改进的岩性识别模型、泥质含量校正模型、包含泥质含量参数的孔隙度和渗透率解释模型、动态电阻率油层识别模型,在研究区应用后取得了好的应用效果。经试油资料验证,油、水、干层解释准确率88.24%,初步解决了研究区有效储层难于识别的难题,对油田今后调整挖潜具有重要意义。Aimed at the high-shale-content,low-permeability and complex-lithology reservoirs in the sedimentary system like the subsea apron,by taking Lishuwa Oilfield as the object of study and based on the data of well logging,core analysis,well test and production test,the limitations for identifying complex-lithology reservoirs were determined,an improved lithological identification model,shale content calibration model,improved porosity and permeability interpretation model including the parameter of shale content and the oil layer identification model by the method of dynamic resistivity were established,good application results were obtained in the research area.These models are proven by the well test data,the precision rate is 88.24% for interpreting oil/water/dry layers,it initially solves the problem of recognizing the effective reservoirs in the area,it is of great significance for future adjustment and potential tapping for exploitation of the oilfield.
