玛北油田三叠系百口泉组储层四性关系研究

利用岩芯、测井、试油、分析化验等资料，对准噶尔盆地玛北油田三叠系百口泉组的岩性、岩石学特征、物性及含油性等关系进行分析，总结岩性与电性、物性及含油气性之间的关系及影响因素，得出孔隙度、渗透率及含油饱和度等油层参数的解释模型。研究表明，岩石类型、粒度、分选、泥质含量，以及胶结物类型等是控制百口泉组储层物性的关键因素；各种岩性的含油产状普遍较高，砾岩、砂砾岩和含砾砂岩含油产状较好；储层具有物性变好，含油显示级别升高的特点；储层物性，含油饱和度，以及地层电阻率呈正相关。通过对百口泉组储层四性关系的研究，并根据试油资料与储层物性、电性参数交会，制定了油、水、干层的定量解释标准，为下一步的油气勘探与开发工作提供了科学依据。

Study on Four Property Relationship of Baikouquan Formation inTriassic，Mabei Oilfield，Junggar Basin

The lithology，electrical property，physical property and oiliness of Baikouquan Formation in Triassic，MabeiOilfield，Junggar Basin were analyzed by using data of drill core，well logging，oil testing and analysis test. Their relationshipand affecting factors are summed up，and the interpretation models of porosity，permeability，and oil saturation were established.The research indicates that rock pattern，grain size，sorting，shaliness and cements type are key factors of controlling physicalproperty of oil reservoir. Most of lithology have good oil-bearing occurrence，especially conglomerate，glutenite and gravelbearingsandstone. The grade of oil display is gradually increased with physical property. There is also a positive correlationbetween oil saturation，formation resistivity and physical property. Through the research of four property，as well as the crossplot of oil testing，physical and electrical parameters，the quantitative interpretation standard of oil reservoir for Baikouquanformation was established to divide oil layer，acquifer and dry layer. Therefore，it provides the scientific evidence for futurepetroleum development and exploration.
