中文摘要	通过岩石薄片、铸体薄片观察等方法,对巴喀油田下侏罗统八道湾组储层进行岩石学特征、储集空间类型、物性特征等研究,并对八道湾组储层进行综合分类评价。结果表明,八道湾组储层以长石岩屑砂岩和岩屑砂岩为主;孔隙类型包括粒内溶孔、剩余粒间孔、基质微孔和微裂缝;储层平均孔隙度5.9%,平均渗透率0.40×10-3μm2,属特低孔、特低渗储层。结合孔渗关系曲线及含气性等参数,将研究区储层划分为三种类型,其中Ⅰ、Ⅱ类为有效储层,Ⅲ类为非储层,以Ⅱ类储层为主。; In analyzing the conventional rock sections and casting slices,the lithology characteristics,reservoir space feature,and physical property of Badaowan formation of Lower Jurassic in Baka oilfield were studied to explain the comprehensive classification evaluation.The findings include the following:Badaowan Formation are mainly debrisfeldspar and feldspar-debris sandstone;the main types of sandstone pore are intragranular dissolved pore,remainder intergranular pore,matrix pore and microfissure;the average porosity and average permeability are 5.9%and 0.40× 10-3 μm2 respectively,thus the reservoir is extremely low in porosity and permeability.In term of porosity,permeability,gas potential and other parameters,the sand reservoir can be divided into three types,that is,I and II(effective reservoirs)and III(bad reservoir),while the reservoir are mainly of type II.
