摘要/Abstract

摘要： 泌阳凹陷安棚油田深层系目前是河南石油勘探局重点勘探层位,其储集层特征及控制因素研究对该油田勘探开发具有重要指导意义。埋深大于2800m的古近系核桃园组三段下亚段,属于扇三角洲沉积。其储集空间主要分粒间孔、溶蚀孔和裂缝,以残佘粒间和溶蚀孔为主。细喉和微喉占主导地位,喉道连通差,非均质性强,为典型的低孔、低渗-特低渗储集层。储集物性的变化主要受控于沉积相、成岩作用及构造等因素。扇三角洲是储集性能最好的相带,远砂坝、前缘席状砂和近源水下分支河道储集性能较差。晚成岩B期次生溶孔发育;背斜轴部裂缝发育,翼部裂缝较少。

Abstract: The deep series of strata in Anpeng oilfield of Biyang depression is as the major explorative horizon at present by Henan Petroleum Exploration Bureau. Study of its reservoir characteristics and controlled factors is of great significance for exploration and development of this oilfield. The lower sub-member of No.3 member, Hetaoyuan formation of Paleogene belongs to fan delta deposits with buried depth of over 2 800m. The reservoir pore space mainly consists of intergranular pore, solution pore and fracture, dominated by residual intergralar pores and solution pores. Slim throat, micro-throat, poor throat connectivity and serious heterogeneity make it become a typical reservoir with low porosity, low permeability to extra low permeability. The variation of reservoir petrophysical property is primarily controlled by sedimentary facies, diage-nesis and structure in it. The best facies of reservoir capacity is the fan delta, lhose of others like distal sandbar, frontal sand sheet and proximal underwater distributary channel are poor. Secondary solution pores are generally found in B epoch of late diagenesis; fractures occurs on axis of the anticline, seldom on sides.

Key words: Biyang sag, reservoir characteristic, sedimentary facies, diagenesis
