摘　　要：近年来渤中凹陷相继发现了数个大型油气田,为了分析渤中凹陷西斜坡的勘探潜力,利用勘探初期的地化录井资料,通过地球化学方法对研究区域的东营组烃源岩进行初步分析,研究表明研究区东营组下段在3 389～3 680 m是段较好的烃源岩,厚度大约200 m,有机质类型主要为Ⅱ1型,且已进入成熟阶段;利用氢指数估算的生烃量表明,已经生成或者排出烃源岩的油气量是相当可观的,说明该区具有一定的勘探潜力。In recent years, several large oil and gas fields have been discovered in Bozhong depression. To analyze an exploration potential of the western slope in this depression, preliminary analysis has been carried out for the source rock of Dongying Formation by both geochemical mud- logging data from an early exploration stage and geochemical method. Results show that at the depth ranging from 3 389 m to 3 680 m, good source rock exists at the lower Dongying Formation, with 200 m in thickness, II1 type of organic matter, and good maturity. Hydrocarbon-generating content calculated by hydrogen index indicates that this is a prospective area with considerable hydrocarbon.
