| 摘 要： | 对惠民凹陷的地震、测井、岩心、重矿物及粒度资料进行了综合分析，总结了惠民凹陷下第三系沙河街组三段中上部临商地区基山砂体的沉积特征、物源、古水流、砂体展布、成因及石油地质意义。基山砂体物源来自北部埕宁隆起，是一套洪水重力流成因的深水浊积扇砂体，属扇三角洲—沟道—深水浊积扇沉积模式，砂体呈扇形展布，分别向东、西、南３个方向尖灭，具有丰富的油源，可形成良好的岩性尖灭油气藏，可以作为重点勘探目标

| Abstract: | Sedimentary characteristics, provenance, paleo\|current, distribution, origin and
significance for petroleum geology of Jishan sand body were systematically described on the
basis of comprehensive analysis on seismic, logging, core, heavy mineral and grain size
information. Jishan sand body from Chengning uplift is a turbidity fan sandbody being of flood
gravity flow sedimentation origin, and it belongs to a sedimentary model of fan
delta\|channel\|deep water turbidity fan. It pinches out to three directions of east, west and
south, and it is surrounded by abundant source rock. It may form a favorable lithologic pinchout
and has good potentials for exploration.\= |
