摘要
北大港油田马东开发区到目前已经历了二十多年的开发生产,随着新资料的增加,对其地质认识程度有了新的变化。为了给测井解释和储量计算提供依据,对沙一段储集层开展了"四性"关系特征研究。利用岩心、测井、试油和分析化验等资料,在测井数据标准化和岩心归位的基础上,研究目的层位的岩性、物性、电性及含油性特征及其相互关系,从而确定该区沙一段油层有效厚度下限标准。利用该标准进行老井油层复查和新井有效厚度划分,有效地提高了综合解释符合率,为该区储量计算和油田开发方案设计提供了可靠的依据。
Madong Development Area of North Dagang Oilfield has experienced more than two decades' development and production.New changes have taken place in the level of geological knowledge with the raise in new information.To provide the basis for well logging interpretation and calculation of oil reserves,the authors made a study on the relationship of four characteristics of Es1 reservoir.Using core,well logging,oil testing and laboratory analysis,the authors researched the features and relationship of lithology,physical properties,electrical behavior and oiliness on the basis of well logging data standardization and core proper-horizon restoration,thus determining the lowest standard of effective thickness of Es1 oil layer in Madong Development Area.Using this standard to counter check the old wells and divide effective thickness of new oil wells improved the coincidence rate of comprehensive interpretation and provided a reliable basis for reserves calculation and oilfield development project design of Madong Development Area.
