The Reservoir Deliverability Analysis Of Chang8Reservoir In Wang Pan Mountain Wellblock-44010

Wang pan mountain wellblock-44010belongs to Fan Xue oil region of Dingbian, is the main increase production region of Dingbian oil production plants, Section structure is located in northwest boundary of yishan slope belt in ordos basin, Most area of the basin is made up by thick river facies of the upper and lower layers and sand, fine sandstone cyclothem of subfacies light gray sandstone in deltaic plain, Stratification constitute development, between thin layers mudstone and dark mudstone. The alternate layer of thick mudstone and sandstone mudstone is in the center of subsidence of southwest basin. Chang8reservoir is mainly with underwater distributary channel in the northwest, The reservoir lithology is mainly with fine, medium lithic arkose and feldspathic lithic sandstone. Controlled by lithology, edge-bottom water is inactive, but plane distribution is wide, the area is large, the reservoir property of Chang8is poor, it is low porosity, low permeability reservoir.According to the data of production test, the chang8containing water of oil well has big differences in the study area, that reflects the heterogeneity on the plane is stronger, but the water content of single well is steady. In the area of well production capability, and under the condition of natural depletion, the production of oil well decline rapidly, reflect the reservoir pressure of Chang8decline quickly, that define producing energy is very poor. According to reservoir geological characteristics of Chang8, this paper analysed and studied the reservoir deliverability. Based on the analytical data of lithologic character and physical property, analysis and study reservoir geological characteristics of Chang8, study reservoir characteristics of the main oil-bearing series; Demonstrate well pattern rationality of Chang8in the study area and index prediction of waterflood development, and thus analyse reservoir characteristic of Chang8in the study area scientifically and strictly, determine the reasonable development method. Combine the actual situation of production development of Dingbian oil production plants, determine production, water injection pressure and development method, single well production capacity of that suit the reservoir characteristic Chang8in the study area, and determine the reasonable production parameter, such as injector producer distance and row spacing.
