摘要

大城凸起是华北油田深小潜山勘探油气较为富集的区域,潜山内幕成藏条件复杂,圈闭发现、落实、成藏评价难度大,区域潜山数量多、分布广、油藏类型丰富,潜力巨大。利用石油地质生储盖、圈运保厚理对大城凸起的三维地震资料构造解释进行了综合分析,分类研究了大坡凸起潜山油气藏成藏条件,并进行了圈闭精细落实与评价。研究表明,生、储、盖空间组合较台理,断层发育,石炭-二叠系内砂体发育,工区油源供给条件好,存在有利油气运移通道,具备一定的封盖条件;大城区凸起为改造破坏型构造单元,是Ⅱ类较有利地区,具有一定勘探潜力。
Dacheng Swell of Huabei Oilfield is a deep but small buried oil and gas enrichment exploration area,the buried hill hydrocarbon accumulation conditions are complex,traps,implementation,evaluation of hydrocarbon accumulation are difficult;large number of buried hills are widely distributed in Dacheng Operation Area,reservoir type is rich with great potential.By using source rock,reservoir caprock,trap,movement and conserving theory of comprehensive security analysis and the operation area are studied by 3D structural interpretation of seismic data,classifying of Dacheng buried hill and researching of reservoir accumulation conditions,oil reservoir,cap space combination is more reasonable to fault development,Carboniferous-Permian sandstone within the development area is good source of oil supply conditions,there is a favorable oil migration channel with a certain cover conditions and a certain exploration potential,it is a reconstructed and breaking tectonic unit,it is a ClassⅡarea.
