摘要
西非深水区受复杂构造活动、盐岩活动、泥底辟活动、深水重力流作用等因素影响,地质条件异常复杂,需要在创新地质认识的同时,大力开展地球物理技术的创新与应用。针对西非深水区复杂断块构造、盐下构造、深水水道沉积储层和碳酸盐岩沉积储层等复杂地质难题,研究建立了深水区低信噪比地震资料处理、深水区复杂构造精细评价、复杂浊积储层描述及深水碳酸盐岩储层预测等一系列地球物理关键技术体系,并在应用实践中取得了良好的勘探成效,有效促进了中海油在西非深水领域的油气勘探进程。
Under the impacts of complex tectonic movement, salt action, mud diapirism and gravity flow in deep water, there are very complicated geo- logical conditions in West Africa deepwater region, where geophysical prospecting techniques need to be innovated and applied while innovating the geologic awareness. For a number of geological problems, such as complex faulted block, subsalt structure, deep-water channel reservoir and carbonate reservoir, a series of key geophysical techniques were researched and established, including the seis- mic processing technique for low signal/noise ratio data in deep water, the refined evaluation technique of complex structure and the prediction technique of complex turbidite reservoir and deep water carbonate reservoir. Their actual application has resulted in good exploration efficiecy, effectively promoting the process of CNOOC hydrocarbon exploration in West Africa deep water region.
