摘要:

通过岩芯观察并利用普通薄片、铸体薄片和扫描电镜分析等资料,对金秋区块须四段储层的成岩作用、成岩
矿物、成岩阶段和成岩演化序列等进行了研究。根据成岩作用、成岩矿物等将须四段储层划分为压实致密、碳酸盐胶
结致密、伊/蒙混层充填、不稳定组分溶蚀和绿泥石环边胶结5 种成岩相。选取自然伽马、电阻率、密度、中子和自然伽
马能谱等测井曲线,建立了各成岩相的测井识别标准,并对JH1 井的测井资料进行了处理,得到了其成岩相剖面展布
规律。根据成岩相识别与物性分析的匹配结果,认为在裂缝不发育的情况下,绿泥石环边胶结和不稳定组分溶蚀相发
育层段物性最好,伊/蒙混层充填相次之,压实致密相再次之,碳酸盐胶结致密相最差。

Abstract:

The diagenesis,diagenetic minerals,diagenetic stage and diagenetic evolution sequence of Xujiahe Formation
Member 4 reservoir in Jinqiu Area are studied by the normal thin sections,casting thin sections,X-ray diffraction scanning
electron microscope analysis data. Five types of diagenetic facies are divided based on diagenesis,diagenetic minerals and
its impact on reservoir property:compaction tight facies,carbonate cementation tight facies,illite and montmorillonite mixed
layer filling facies,corrosion of unstable components facies and chlorite mat cementation facies. A series of logging curves
including compensated neutron logging,density logging,natural gamma ray,array induction log and spectral gamma-ray log,
are sensitive to the diagenetic facies. Actual log data of Well Jin1 were processed with the built logging identification model,
and the vertical distribution law of diagenetic facies in Well Jin1 is figured out by the well logging data. When the logging
recognition result of diagenetic facies in Well Jin 1 is corresponded with the reservoir physical property analysis data,it is
found that the layer with the corrosion of unstable components facies and chlorite mat cementation diagenetic facies are the
best,while the compaction tight facies illite and montmorillonite mixed layer filling facies are relatively worse,the reservoir
property of the carbonate cementation tight diagenetic facies are the worst.
