摘要
针对浅层气藏具有埋藏浅,成因复杂,储量小,丰度低,类型多,分布广,压力偏低的特点。以松辽盆地北部葡南地区黑帝庙气藏为例,对浅层气藏的成藏主控因素进行了研究。葡南丰富的烃源条件为油气富集提供了资源基础;优质盖层条件及稳定的地下水条件为天然气的保存起到了重要作用;T1-T06或T2-T06断层的发育及分布是该区黑帝庙油层油气聚集的必要条件;明水组地层变形前后构造格局的演变对黑帝庙油气藏的再改造起到重要作用,古构造高带也是天然气运聚的有利地带;黑帝庙油层良好的储层条件为油气的储集提供了有利场所。从已有气藏的解剖看,砂体、构造、断层相互配合控制了油气的聚集,是油气成藏关键。总结了黑帝庙油层的成藏模式。对同类浅层气藏的勘探开发具有一定的指导意义。
Generally,the shallow gas reservoirs refer to what are buried in the shallow with complex origin,not rich reserve,low abundance,wide distribution,low pressure and so on.In this article,the authors research the the controlling factors of shallow gas reservoir by setting a example of Heidimiao reservoir of Punan area,northern Songliao Basin.In this area,rich hydrocarbon source in the area provides a resource base,qualitified cover conditions and stable groundwater conditions for preservation of natural gas play an important role,T1-T06 or T2-T06 fault development and distribution are the necessary conditions for the Heidimiao oil and gas accumulation,the evolution of tectonic deformation before and after Mingshui inversion plays a further role in the transformation of the distribution of oil and gas,the high palaeostructure bands also are favorable,which gas migrated and accumulated to,Heidimiao oil layer is of good reservoir conditions,which provides a favorable environment for oil and gas reservoir,match of the sand bodies,structure and fault control the hydrocarbon accumulation and is the key.The authors sum up the accumulation model of Heidimiao oil layer on the basis of the research above.The research results can guide the exploration and development of the similar shallow gas reservoirs to a certain extent.
