摘要

姬塬油田长 9 油层组是滚动勘探的有利接替层位,在不同地区其成藏条件和油藏富集程度存在明 显的差异性。 通过岩心观察、测井解释、样品测试及相关模拟实验,从烃源岩、储集体及其之间的通道、距 离和动力等方面对比分析了姬塬油田红井子、胡尖山及罗庞塬地区长 9 油层组油气聚集成藏的差异性。 结果表明:红井子地区紧邻生烃中心,储层物性好,源储压差大,油气富集程度高;胡尖山地区储集物性较 好,但距离生烃灶较远,源储压差较小,油气富集程度一般;罗庞塬地区源储压差较小,裂缝不发育,储集 物性差,油气富集程度较差。

Abstract

The Chang 9 oil reservoir set in Jiyuan Oilfield is a favorable layer to replace for rolling exploration, and there are obvious differences on oil reservoir conditions and enrichment degree in different areas. Based on core observation, logging interpretation, sample testing and related simulation experiments, from hydrocarbon kitchen, the channel between the reservoir and the distance, dynamic, this paper compared and analyzed the hydrocarbon accumulation differences of Chang 9 oil reservoir set in Hongjingzi, Hujianshan and Luopangyuan areas. The results show that Hongjingzi area is near the hydrocarbon source rocks, reservoir properties are also good, source reservoir pressure is strong, so this area is favorable for hydrocarbon enrichment; Hujianshan area has good reservoir properties, but it is relatively distant from the hydrocarbon kitchen, and the source reservoir pressure is small, so hydrocarbon enrichment degree is general; in Luopangyuan area, source reservoir pressure is small, fracture was not developd, and reservoir properties are poor, so hydrocarbon enrichment degree is poor.
