盐北地区浅层天然气成藏因素与勘探潜力
|
摘要
对盐北地区浅层天然气成藏的主控因素和成藏特征进行了综合分析,证实烃源岩、断层、不整合面及盖层是盐北地区浅层天然气成藏的主控因素;气藏的地震反射特征明显、具有优越的储盖组合及多种类型的成藏模式是浅层天然气的成藏特点;明化镇组广泛分布的岩性气藏及断层-岩性气藏是浅层天然气勘探开发的主要方向。
Synthetic analysis is carried out for the main controlling factors and accumulation characteristics of shallow gas accumulation in Yanbei Area. The study result has shown that the main controlling factors of shallow gas accumulation are the hydrocarbon source rocks,faults,uncomformable surfaces and cap formations. The seismic reflection characteristics,favorite reservoir-seal assemblage and many types of accumulation models of gas reservoir are the accumulation characteristics of shallow gas reservoir. The main direction of gas exploration is the lithologic gas reservoirs and the structure -lithology gas reservoirs distributed widely in Minghuazhen Formation.
