The Reservoir Descriotion Of Chang6in HuaiShuzhuang Area Of Fu Huang Block

HuaiShuzhuang Area of Fu Huang Block is located in southwest of FuXian, Itstectonic units the Yishan slope. Fu Huang Block is240Km2,the major reservoir is theChang-6oil layer of Yanchang Formation. The favorable petroliferous area ofHuaiShuzhuang Area is poor reservoir property and belongs to low porosity, lowpermeability reservoir, and oil-bearing property is poor, the test oil yield is not high.On the basic of previous research,we take fine strata classification andcorrelation theory as instruction divided and compared to strata in entire area andmake a deep division to Chang6formation and get three oil bearing series. The articleis theoretically based on reservoir geology, reservoir sedimentology,reservoir welllogging geology, exploration geology etc and analyses all kinds of the sedimentarycharacteristic comprehensively. Using core, well logging, we judge Chang6formation is deep lake facies and grows mainly middle fan intrafacies, deep fanintrafacies. Based on source direction and sedimentary facies, the article did theresearch of sandbodies distribution characteristic. Reservoir stratum property, fourcharacter, aeolotroprism and micro pore structure of reservoir, Flow Unit, Pressuresystem, distribution of oil and water are also analysed. using Petrel the article did thetectonic model, reservoir model, fluid model, using Stochastic Modeling analysis theporosity and Permeability of reservoir. On the basis of the systematic description andevaluation of various properties, enriched rules of the area are conclued and the datarange of profitability is anticipated. These provide a new basis for the area of oil andgas exploration for the next step.
