胡力海洼陷储层特征及控制因素研究
|
摘要
采用钻井、测井、地震等技术,综合化验分析等资料,对钱家店凹陷胡力海洼陷储层的岩性、储集物性及储集空问特征等进行了研究。胡力海洼陷储层的岩性为一套结构和成分成熟度均很低的陆源碎屑岩(主要为中酸性喷出岩、变质岩岩屑和长石),主要储集空间是粒间溶孔、粒内溶孔和微孔,储集物性为低孔、低渗,储层物性主要受岩性、埋藏深度、沉积相、纵向分布层位的影响,且以沉积作用和成岩作用为主。
For the reservoir of Hulihai Subsag in Qianjiadian Depression,its reservoir lithology.physical property of reservoir and spatial characteristics are studied by drilling,logging,seismic and laboratory analysis data.The comprehensive evaluation show that the lithology of the HuLiHai reservoir is a set of terrigenous clastic rocks the structure and component maturity are very low(mainly for the medium-acid extrusive rock,metamorphic cuttings and feldspar);The main reservoir space is dissolved pores between grains,dissolved pores in grains and microporous.reservoir physical property is low permeability and low porosity:the main control factors of the reservoirs' physical properties are lithology.buried depth,the sedimentary facies.the influence of vertical distribution layer,and the deposition and diagenesis are main factors.The conclusion provides geological basis for the future oil exploration and development.
