摘　　要：通过压汞、铸体、电镜、Ｘ 衍射、裂缝单井测井解释和平面预测， 并结合其它地质和流体测试资料， 综合研究认为， 安棚深层系储层矿物成熟度低， 稳定性差， 次生加大明显， 储层以特低渗中孔细喉分布为主， 属于较差的储集类型， 同时储层裂缝发育尤以中小水平裂缝分布广泛， 裂缝的发育程度与构造位置和所受到的地应力有关， 大裂缝对储层损害严重。This paper studies the mercury injection, cast body, electron microscope, X-diffraction, single well logging interpretation and areal prediction of fractures combining with some other geologic and fluid testing data. The conclusion is that the reservoirs in Anpeng deep series of strata have a low maturity of mineral and apparent stability secondary accretion. They are poor reservoirs with mainly very low permeability and middle pore throat distribution. Reservoir fractures develop with mainly middle and small horizontal fractures. The development of fractures is related to structures position and earth stress. Large fractures damage the reservoirs seriously.
