摘　　要：多物源薄砂体研究主要依据地层沉积韵律旋回反映在组合测井曲线上的特征，划分沉积类型确定砂体空间展布，多物源优砂体交汇配置关系和剖面上的叠置层序。应用于井楼油田ＩＶ＾３Ｔ油层研究，砂层对比确认为３个物源方向的砂体，在平面上相互交汇，剖面上依次叠置。The study on multisource thin sand body is todifferentiate deposition types, determine the distribution ofsand body, the relationship, and the laminating successionof the multisource sand body in the profile according tothe characteristics of sedimentary rhythmic cycles of thestratigraphic deposition in the combination log. The sandbody, Ⅳ_5~3 layer of Jinglou oilfield, can be furtherdivided into three oil-bearing ones, which converge witheach other and superimpose in the profile. It is confirmedby drilling that the oil-bearing area has increased by 3.0km2, and that 1.14 million more tons geologic reservcswas newly found.
