摘要:
高效、准确获取储层有效孔隙度是油气勘探与开发中的重要一环。大港探区埕海油田由于有多家测井公司开展测井作业,已有的测井资料复杂多样,为测井资料计算有效孔隙度增加了难度。通过分析随钻测井与常规电缆测井资料之间的关系,在岩心归位的基础上,针对埕海油田中生界储层,开展有效孔隙度计算方法研究,建立了有效孔隙度模型。该模型应用于埕海中生界储量研究,测井计算孔隙度经岩心标定后,相对误差仅在-3.07%~4.41%之间,能够满足储层孔隙度评价精度要求。由于储集岩性多以砂岩为主,岩石骨架密度差异不大,研究模型可以应用于渤海海域大港探区以"四组合"随钻测井系列为主的勘探区。
Abstract:
The efficient and accurate acquisition of effective reservoir porosity is an important part of oil and gas exploration and development. Due to logging operations carried out by many logging companies in Chenghai Oilfield in Dagang Exploration Area,the existing logging data is complex and diverse,which makes it more difficult to calculate the effective porosity for the logging data.By analyzing the relationship between logging-while-drilling and conventional wireline logging data,based on core homing,for the Mesozoic reservoir in Chenghai Oilfield,the effective porosity calculation method was studied,and the effective porosity model was established.The model was applied to the study of Chenghai Mesozoic reserves.After logging calculated porosity was calibrated by core,the relative error was only -3.07%-4.41%,which can meet the accuracy requirements of reservoir porosity evaluation.Since most of the reservoir lithology is sandstone,and the density of the rock skeleton is little different,the research model can be applied to the Dagang Exploration Area in the Bohai Sea,which is dominated by the “four combinations”(natural gamma,resistivity,density,neutron) logging-while-drilling series.
