利用三维叠前地震资料预测火成岩储层裂缝分布
|
摘要
本文基于地球物理技术综合一体化应用的思路,将地震资料裂缝预测、孔洞检测等技术综合应用于复杂的储层预测与描述中;在逆断层发育区采取分断块分层预测、分层整体评价的策略,解决了逆断层地震属性平面成图的难题;通过裂缝研究,查明准噶尔盆地西北缘七东区石炭系不同期次裂缝的平面、纵向分布规律;结合试油、试采成果资料,优选出有利开发区,取得了较好的火成岩储层预测效果。
Based on geophysical integration thoughts,seismic data fracture prediction techniques were integratedly applied in complex reservoir prediction and characteristics in this paper.In reverse fault development areas,the prediction and detection were conducted for every block and every layer,and then layer by layer over-all evaluation was carried out,as a result the difficulty for mapping reserve fault seismic attribute was solved.Through studies on fracture prediction,horizontal and vertical fracture distribution laws in Carboniferous different layers for Qidong area of Junggar Basin Northwest margin were understood.By analyzing oil test and production test results,the favorite development areas were optimized,excellent igneous rock reservoir prediction effects were achieved.
