摘　　要：开发苏里格气田的一个关键地质问题就是准确预测有效砂体的分布。以苏里格气田Su6井区为例,综合测井、露头和测试等信息,采用示性点过程随机模拟方法,分别建立了Su6井区含气目的层段的辫状河道体系三维模型和有效砂体分布三维模型,揭露了辫状河道和有效砂体分布规律。预测结果能较好地反映Su6井区有效砂体分布的复杂性,具有一定的可信性和预测性,这为开发井部署及数值模拟奠定了坚实的基础。A key problem for effective development of Sulige Gasfield is to predict the distribution of net sandstone precisely. Well Su6 in Sulige Gasfield is taken for an example. Through applying marked point process technique, 3D models of braided-channel and net sandstone are constructed by combining data of logs, outcrops, testing, etc. these models display distributions of braided-channel and net sandstone. The results can be used to present the complexity of the distribution of net sandstone in Well Su6 with a certain reliability and predictability, which lays a solid foundation for further arranging production wells and numerical simulation.
