Xinzhuang Chang6Reservoir Oil Reservoir Evaluation

Ordos Basin is one of the earliest discovered Basin oilfield, after several generations ofhard work of oil, its oil and gas exploration has made remarkable achievements. After thestudy found that most of the oil in the Ordos Basin, Upper Triassic strata are Yanchang, its oilreserves, oil-bearing area is very rich, and crude oil production increased year by year. In thispaper, Shinjo oil reservoir Chang6reservoir classification for the study were evaluated in thestudy to microfacies, geological characteristics as the basis for macroscopic and microscopiccharacteristics of the reservoir geological characteristics of the main line, summarizing theresults of a large number of previous studies basis, from the macro to micro, from qualitativeto quantitative analyzed.XinZhuang Ordos Basin oil Chang6oil exploration and development in recent years,have achieved good results. But the area is poor physical properties of sand, diagenesiscomplex impact on the further development and submission of controlled reserves haveimportant. To find out the distribution of the area with high porosity, scientific and reasonableto predict reservoir distribution in the region, the paper in-depth study of the Chang6reservoirsand body distribution characteristics, microscopic pore structure characteristics, the impact ofdiagenesis on porosity, ultimate combination of sedimentation, diagenesis, microscopic poreresearch results, the study area for a reasonable prediction of favorable reservoir.In this paper, XinZhuang oil reservoir Chang6conducted a comprehensive analysis ofmulti-level study: First, from the reservoir causes, impact assessment and classification of thetype of reservoir analysis, the impact of the reservoir is mainly tectonic, sedimentary anddiagenesis; the second is from depositional system development and reservoir types wereanalyzed; the third is the evolution from diagenesis different effects on reservoir spaceresearch, summed up the basic geological characteristics Shinjo oil region. In addition to thetheory of sequence stratigraphy, sedimentary petrology, logging geology and other relateddisciplines as a support, the impact of reservoir properties from the reservoir, reservoirdistribution, fluid properties, lithology, fracture development in five areas a comprehensivestudy by the preferred method of reservoir evaluation, and finally preferred to reflect the most the most essential features of reservoir parameters and to reflect the most significant featuresof the reservoir as the best comprehensive evaluation index. Finally, as the main geological,integrated application of geological, coring, logging and analysis data to theory sedimentology,logging geology, geology developed as a guide to track the progress of the current field of newcomprehensive study of geological and abroad. Proceed from the basic geological research,the new village in Chang6oil reservoir group conducted a comprehensive study of the wholebasis of the system, the preferred quantitative development programs, to predict the optimalwater development programs in this area. Under the unified geological ideas weremultidisciplinary, comprehensive study of mutual penetration deepens the understanding ofreservoir characteristics again.
