Chaoyang Groove Optimization Of Oilfield, A Block In Fuyu Reservoir Favorable

In recent years, for the oil recovery plant and Jilin Changchunling oil field in the Changchunling anticline, the proven reserves of the ideal situation, this will focus on the transfer to the long 80 block, long 80 wells exist sand body changes, Therefore, in order to further implement the production characteristics of the area, comprehensive utilization of seismic, geological and logging data, based on the study of seismic sedimentology, select A block, an area of 12.9km2, the use of Zhaoyuan, the use of water and water resources, In the south of the three-dimensional seismic work area, based on the analysis of seismic attributes and the seismic seismic inversion, the characteristics of sand body identification and oil-water distribution are further deepened. Based on this, the reserves potential block is preferred. The oil-water interface, source, oil source, hydrocarbon generation and hydrocarbon history of the fault block are studied by combining the logging data of the well and the oil test results.Development history, sand body distribution characteristics, reservoir physical properties and other characteristics, to determine the main reservoir type. According to the results of test oil test in the study area, the single well production capacity of the Fuyu reservoir, the reservoir master control parameters, the effective thickness, the oil yield and the reservoir property and other factors are established to optimize the reserves, the favorable blocks are estimated, the geological reserves are estimated, Explore new ways to improve capacity development.The study area is located in the southwest slope area of Chaoyanggou terrace and Changchunling anticline, which is low in northwest and high in southeast. There are two types of anticline and nasal structures. In order to solve the characteristics of the reservoir physical properties in the study area, the distribution of the main part of the southeastern area,the main northwest area and the A district Block effective porosity and oil saturation model.According to the reserve area delineation principle and the preferred evaluation standard, the reserve potential block is selected, and the horizontal well fracturing and mining mode is preferred.
