Geological Modeling of Combined Incised-Channel System in Deep-water Sediment Gravity Flow Deposits:A Case of Block OML130 in Niger Delta Basin, West Africa
摘要
Abstract
The deep-water sediment gravity flow deposits in Niger Delta Basin is an important exploration and development target in West Africa. The reservoir group A of AKPO oilfield in Block OML130 is mainly composed of combined incised-channel system. The channels in different periods overlap each other vertically, and they are partially cut and connected, which is very important for oil field development. In view of the above geological characteristics, a modeling framework is adopted to reconstruct the vertical aggradation and lateral swaying. With the help of the information of time-lapse seismic monitoring, the water-flooding area is detected and the connected areas of incised channels are picked out, by which a quantitative identification method is formed for incised area between different channels. Under many restrictive conditions, a reliable model of sedimentary microfacies is established. And the post-production dynamic verification is effective, which proves that the modeling method has a high practical value.关键词
