Study Of Reservoir Charactertistics Of The Middle Section Of The Third Strata Of Shahejie Formation Of Qiaozhuang Oilfield

The oil-field development contains the content broadly, theinfluence factor are many, the research difficulty is a big andcomplex systems, especially said to the old oil field such Shenglioil field, enables oil field under the guarantee certain economicefficiency the recovery ratio to achieve high appears importantly,therefore conducts the scrutiny to the reservoir to have the practicalsignificance. This research through to the analysis on miningpresent situation of QiaoZhuang oil field, use lithologicalcharacter, electric properties, depositional cycle and stratumdepth has carried on the division and the contrast to the Sha sanzhong formation of QiaoZhuang oil field. Based on the stratigraphiccorrelation and division, has carried on the analysis to the keysubzone top structure. And through facies mark and individual wellfacies analyzes, has conducted the research to the sedimentaryfacies of Sha san zhong reservoirs, then has studied thenonuniformity of internal and interlamination of reservoir, hasanalyzed the change rule of porosity and the penetration coefficient.Established the lothological parameter to explain the model, thereservoir natural parameter well .logging interpretation model, theoil saturation explanation model. Through the analysis on characterof reservoir plane and the section plane, oil gas reservoir typemainly has following four kinds in the research area: Fault and nosestructure oil gas reservoir, the lenticular body oil gas reservoir,fault and lithologic compounded oil gas reservoir and thelothological oil gas reservoir, fault and nose structure oil gasreservoir is the most type, appears the oil gas pool in the researcharea and the non-main force granulated substance body which the fault and the lothological pinch-out altogether controls, likelothological lens oil gas reservoir and lothological oil gas reservoir.And firmly decided the pattern of the fault and nose, pattern of thelothological trap oil gas, pattern of the fault trap the oil gas and thepattern of fault and the lothological compounded oil gas reservoir.
