Study On Jurassic Reservoir Perforating Dingbian Oil Production Plant Of Fanxue

Ordos Basin is the second largest sedimentary basin, is superimposed cratonic basins, oiland gas resources. This thesis study area in the basin area Fan northern slope southwesternpart of Yanchang Oilfield Oil Production Plant fixed side, the main reservoir of JurassicYan’an9oil. Fan school district average of10.1%porosity and permeability averaging0.47×10-3μm2, sleeves typical ultra-low permeability reservoirs. Yanchang Oilfield given edgeextraction plant through ten years of exploration and development, has been basically formeda set on low and ultra low permeability reservoir description experience and methods in the oilfield geology, reservoir engineering, laboratory analysis and other technical researchaccumulated a wealth of experience, but Jurassic Yan’an Formation reservoir commissionedthe development of a lack of effective means of judgment, resulting reservoir output loweredge and bottom water coning obvious, see the water fast, water rising fast, stable and shortertime Many problems are not real solution.In response to these issues in order to reservoir sedimentology, reservoir geology,geochemistry and development theory as a guide, a detailed description of the geology of theOrdos Basin. By Jurassic reservoir facies and rock mineralogy study, based on stratigraphyand sedimentary characteristics and its variation, the use of signs layer method, sedimentarycycle method, cross-sectional structure analogy, lithology and rock mineralogy,electroporation measured characteristic curve combination method, stratigraphic thickness ofFrance and many other identification methods integrated sentenced contrast, this area drilledYan’an and Yanchang stratigraphic division and correlation were normalized, developedYanchang reservoir layer method using mark The method of division of strata and furthersummed up the characteristics of each marker bed with electrical measuring curvecharacteristics. After a Fan learn Jurassic reservoir perforating techniques and perforatingparameters comparison and research, the next step for the oil field development andconstruction Gao reasonably efficient production provide technical support.
