摘要
通过泌阳凹陷安棚地区三维地震资料解释、相干分析、可视化解释、双侧向测井、声电成像与地层倾角测井等技术应用 ,对裂缝发育程度与分布特征进行研究 ,发现裂缝发育程度与构造、地应力和沉积相带密切相关 ,构造缝主要集中在鼻状构造轴部 ,高角度裂缝的发育有效改善了深层系储层的渗流条件 ,在构造有利部位部署的B2 5 2、B2 5 3、B2 62等多口探井取得了较好的地质效果 ,2 0 0 1年在该区新增油气地质储量 1 2 3 0× 1 0 4t。
Development and distribution of fractures in Anpeng area in Biyang depression are studied through 3D seismic interpretation, coherent analysis, visualized interpreta-tion, dual lateral logging, acoustic electric imaging and strategraphic dip logging. It is discovered that the development of fractures is closely correlated with structure, terrestrial stress and sedimentary facies. The structural fractures mainly concentrate on the axis of the nose - like structure, and the development of high - angle fractures effectively improves the seepage flow conditions in deep reservoirs. The wells including B252, B253 and B262 positioned on the favorable part of the structure have led to incremental geologic reserves of 12. 3 million tons in 2001.
