摘要：针对新立村油田沙二下亚段物源及其沉积特征不明确的问题，研究中采用C-M图解分析，C.值及黏土矿物分析，测井、录井等资料分析以及砂地比分析等方法。得出其可能为重力流沉积，其次为
砂层组可能为三角洲相的前缘亚相沉积,S24一S21段砂层组可能为三角洲相的平原亚相或者为河流
相沉积；其可能的物源方向为北部的陈家庄凸起及北东向的青坨子凸起的结论。关键词：物源分析；沙二段；沉积体系；沉积特征；砂体预测

Abstract : Aimed at the problems of ambiguous provenance and sedimentary characteristics of lower Es2 submember of Xinlicun oilfield through the C-M graphic analysis, its C, value and clay mineral analysis, logging data analysis and sandstone percent analysis, it was concluded that it is the gravity flow deposits ,followed by traction curent deposits. Through, we can see that it is the low compositional maturity. It can be concluded that its S28 and S27 sand formation may be the lake shore shallow lacustrine sedimentary facies , S27 S25 period of sand group may be the leading edge of delta facies deposition,S24-S21 period of sand group may be plain subfacies and delta facies or fluvial facies sedimentary. We can obtain that the possible source direction is the north for Chenjiazhuang heave or north-east for Qingtuozi heave

0引言
在沉积盆地分析中，物源的分析与研究是不可或缺的研究部分[1-3]。物源的研究与分析有助于确定物源的方向、物源的位置、物源的性质以及物源的组成部分，还可以确定搬运沉积的路径、过程，沉积
的作用。对于现今的沉积区域而言，有助于恢复沉积盆地的古地貌、古环境、古气候，有助于勘探矿产资源。对于石油和天然气而言，有利于确定沉积相、亚相和微相；有助于确定有利砂体、有利地层，从而确定圈闭以及油气藏，为油气勘探和开发提供地质学指导[4-13]
