本文以济阳坳陷惠民凹陷沙三下亚段储集层为研究对象，通过岩心、测井、录井等资料，研究了目的层的岩石学特征，恢复了物源方向、确定了沉积相类型，预测了有利油气勘探的砂体分布。研究得出：惠民凹陷沙三下亚段储集岩主要为灰色中粒长石砂岩与岩屑长石砂岩；沉积物主要来自于鲁西隆起，主要沉积相类型为三角洲前缘亚相，砂体主要发育于水下分流河道与河口砂坝微相。综合砂体厚度、砂地比等成果图件恢复了惠民凹陷沉积相平面展布、预测了三处有利于油气富集的砂体分布范围。

Abstracts: Taking reservoirs in the ES3X stratum in Huimin Sag, Jiyang Depression, as a research focus, we investigated the target bed’s petrologic characteristics and recharge source direction, and determined types of sedimentary faces and predicted advantageous areas for oil and gas exploration based on core, logging, and other data. The results indicate that: (1) rocks of the ES3X stratum in Huimin Sag are mainly gray medium-grained arkose and cutting arkose; (2) the sediments are mainly from the Luxi uplift; and (3) the main sedimentary faces is a delta front facies, with sand bodies developed in underwater distributary channels and on channel mouth bars. Considering the thickness of sand bodies and the ratio of sandstone thickness to mudstone thickness, we recovered the planar distribution of sediments in Huimin Sag, and predicted the distribution of sand bodies favorable for hydrocarbon accumulation.
