摘要
针对巴楚隆起东段奥陶系良里塔格组的碳酸盐岩地层,在储层发育特征分析的基础上,通过多种技术对该地区目的层进行了储层预测。首先,联合今构造和古地貌圈定宏观有利油气运聚区;然后,利用趋势面、构造应力预测技术以及地层倾角梯度属性进行构造裂缝预测;最后,通过地震相和沉积相的划分预测了良里塔格组有利油气相带。通过储层预测技术的应用,总结了良里塔格组储层发育分布规律,并优选出潜在储层发育区域,为研究区下一步勘探部署提供了可靠的理论依据。
Based on the analysis of reservoir development characteristics, a variety of prediction techniques are used to predict the carbonate formation of the Ordovician Lianglitage formation in the eastern section of Bachu uplift. Firstly, the macroscopically favorable areas for oil-gas migration and accumulation are delineated by combining the present structure and paleogeomorphology;then, the trend surface, structural stress prediction technology and stratum dip gradient attribute are used to predict structural fractures;finally, favorable oil-gas zone of Lianglitage formation is predicted by using the division of seismic facies and sedimentary facies. Based on the application of reservoir prediction technologies, the development and distribution of reservoir in Lianglitage formation is summarized, and the potential reservoir development area is optimized, which provides scientific basis for the next exploration and deployment of the oilfield.
