准噶尔盆地白家海凸起三工河组岩性油气藏勘探
|
摘要
根据岩心、测井、测试及三维地震资料,采用"井点分析—联合反演/地层切片—砂体解释模型—砂岩圈闭追踪—圈闭优选"的技术思路,对白家海凸起下侏罗统三工河组开展了岩性圈闭预测及优选研究。综合利用JASON稀疏脉冲反演与ISIS全局模拟退火反演各自优势,构建起砂体识别模型,在三工河组一段共识别出13个岩性圈闭,圈闭多分布在西南斜坡区及鼻隆两侧,成藏位置有利。在多成藏控制要素综合分析基础上,优选出8、9号岩性圈闭,提交白家2井、白家3井井位,并获得了良好的钻探效果。
Based on core,logging,testing and 3D seismic data,by viewpoint of "well spot analysis-combination inversion/formation thin section-sandbody interpretation model-sandstone trapped tracking-trap optimization",this paper presents the lithological trap prediction and optimization research of the Jurassic Sangonghe formation in Baijiahai swell.And JASON sparse pulse inversion and ISIS global simulation annealing inversion are applied to develop the sandbody recognition model,by which the total 13 lithological traps have been recognized in the first member of Sangonghe formation,which are mostly distributed in southwest slope area and two sides of nose-like swell,favorable for the oil-gas accumulation.Also,based on multi-factors analysis of oil-gas accumulation control,No.8 and No.9 lithological traps are selected to be drilled at Baijia-2 and Baijia-3 wells,and good drilling results have been gained.
