“两宽一高”地震资料特点及在尼日尔B区块的应用
|
摘要
尼日尔B区块地质条件复杂,断块破碎,断裂活动强烈,断层关系复杂,断裂的平面组合具有多解性,如何准确地刻画断裂系统,是目前需要解决的主要问题。对"两宽一高"三维地震资料的实验及应用,制定适合尼日尔B区块基于"两宽一高"数据的"复杂断块圈闭识别与评价"解释配套技术及储层预测配套技术,为改善成像质量、提高断裂系统识别程度和储层预测及烃类检测精度提供了高品质的地震资料。
The geological conditions of block-B in Niger are complex, with characteristics of broken fault blocks, the intense fault activities, the complex fault relations, and the planar assemblage of fractures is of multiple solutions. How to accurately describe the fault system is the main problem to be solved at present.Based on the experiment and application of "two widths and one height" 3 D seismic data, the matching interpretation and evaluation techniques of "complex fault block trap identification and evaluation" and reservoir prediction techniques suitable for B block of Niger based on "two width and one height" data are formulated, which reduces the exploration risk and provides technical support for exploration and development of this block.
