【摘要】 鄂尔多斯盆地作为我国第二大沉积盆地,其储层特点以低渗为主要特征,作为石油资源的富集地,如何提高此类低渗储层的采收率,加大石油资源的开采开发,促进国民经济的发展,对此类低渗的储层研究就显得尤为重要。因此,本文对B区主力油层长6储层特征及其影响因素进行了分析,以提高低渗储层的采收率。通过分析得到以下结论:储层存在一定的非均质性;胶结作用、压实作用对储层的物性起到消极的破坏作用;溶蚀作用有益于储层流体的渗流,对储层的物性是有益的。更多还原

【Abstract】 Ordos Basin,the second largest sedimentary basin as a country,with its low permeability reservoir characteristics as the main feature,as oil resources enrichment,and how to improve the recovery of such low permeability reservoirs,increase the exploitation of oil resources develop and promote the development of national economy,the study of such low permeability reservoir is particularly important [1]. Therefore,this area of B main reservoir Chang 6 reservoir characteristics and its influencing factors were analyzed,in order to improve the recovery of low permeability reservoirs. Mainly made the following conclusions:(1)There is a certain reservoir heterogeneity;(2)cementation,compaction of the reservoir properties play a negative role in the destruction;(3)dissolution beneficial reservoir fluid flow,reservoir physical properties when beneficial.更多还原
