深水复合浊积水道砂体连通性精细表征技术及应用
|
摘要
深水复合浊积水道沉积体内水道侧向摆动频繁,不同期次水道垂向相互叠合,部分水道下切,砂体展布以及砂体间的连通关系复杂。对如何识别追踪连通区域并建立连通区域的三维模型,前人鲜有研究。针对复合水道复杂连通情况,以西非深水M油田为例,在深水浊积理论指导下,优选纵横波速度比地震属性以及生产动态资料,通过标定砂体叠合区域、确定连通区域(薄互层小于4 m)、可能连通区域(薄互层大于4 m小于15 m),最终实现对水道砂体间连通区域进行针对性地定性、定量化表征,并建立连通区域精细三维地质模型,该方法在M油田中得到了良好的应用效果,探索出了一种表征复合水道连通性的技术方法和流程。
The system of composite deepwater turbidite channels mainly develops composite turbidite channels, in which channels frequently swing laterally, and different stages of turbidite channels are overlapped each other. There is a big uncertainty about the sand body connectivity of the vertical different channels. Few people ever did the research about how to identify the composite turbidite channels or built a three-dimensional model of regional connectivity connected region. To solve the problem, taking M Oilfield in West African deepwater for example, based on the theory of the deep water turbidite, optimizing the VP/VSseismic attributes and production characteristics, identifying "overlapping area", the connectivity area(interbedded<4 m)and probably connected region(4 m
