The group of WZ contains high permeability reservoirs, and is fully developed. The logging interpretation results show considerable reserves for the group of L, with the low permeability reserves up to 82%. The development experience for the group of WZ is not applicable to the group of L. The group of L has the problems of heterogeneity, complicated micro pore structure and difficult water injection. The microscopic pore structure and the distribution of the oil-water displacement of reservoirs are obtained by the experiment technologies of the constant rate mercury, the NMR and the physical simulation of the oil-water displacement. It is shown that the reservoir permeability is 1×10^-3-5×10^-3μm² for the group of L. When the reservoir permeability is below 2×10^-3μm², most throats are less than 1 μm, the filtration resistance is high and the water flooding development is difficult. For the low permeability reservoir, the high formation pressure can significantly improve the displacement efficiency. The residual oil phase permeability is lower than 0.2, the water injection pressure is high, and the small moderate injection is conducive to the effective injection, and keeps a high imbibition efficiency, to improve the reservoir recovery., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=LbY+nDvHmq2Qnu5/NStBDw==, pdfFileSize=2455766, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
