摘要

兴9砾岩体位于廊固凹陷西部大兴断层下降盘中北部,为一岩性凝析气藏。早期钻井5口,2口获得工业油气流,生产稳定。近年来通过开展砾岩体成因分析、岩性油气藏成藏条件研究、高保真地震资料目标处理、精细层位标定、多种地震属性分析,构建了"滑移相砾岩体整体富含油气"和"气藏之下找气藏"的油气成藏模式,通过采取"整体评价、分步实施、滚动评价与产能建设相结合"的策略,滚动评价成果不断扩大,砾岩体储量规模超过百亿立方米。
Xing-9 conglomerate reservoir, a lithologic condensate reservoir, lies in the central and northern of downthrow side of Daxing fault west of Langgu sag. Five wells have been drilled in the conglomerate terrain, two of which have stable commercial oil and gas flow. Through the origin analysis of conglomerate, study on lithologic oil and gas accumulation conditions, target processing of high-fidelity seismic data, fine horizon calibration, and multiple seismic attribute analysis in the past years, the oil and gas reservoir accumulation patterns of "slip-phase conglomerate rich in oil and gas as a whole" and "gas reservoir below gas reservoir" are established. Through adopting the strategy of "evaluating on the whole, implementing step by step, combining rolling evaluation and capacity construction", the rolling evaluation has progressed a lot, and the conglomerate reserves have exceeded 10 billion cubic meters.
