摘要: 在我国东部油田的新生代地层中,多发育大套的红色碎屑岩地层,其中发育有很好的油气藏。红层中油气藏的形成受多种因素影响。对东部油田的红层油气藏的研究表明,沉积与构造是控制红层油气成藏的关键因素,因沉积作用而形成的油气保存条件直接影响圈闭的有效性。厚层泥岩沉积对圈闭的封闭性也有重要影响。对红层中油气藏的分析与对比表明,供油断层与砂岩体相接触、储层侧向与垂向受泥岩或其他岩性或不整合的封堵是形成红层中油气藏的关键因素。

Abstract: There developed many red detrital laterite strata named as red-bed in the Cenozoic stratum of the eastern China oilfields. There are many factors affecting the development of oil-gas pools in the red-bed. The main factors include sedimentation and tectonics. The hydrocarbon accumulation conditions which resulted from sedimentation have controlled the validity of traps. The thick mudstone can control the sealing features of traps. The faults have also controlled the hydrocarbon accumulation in the red-bed reservoir. The traps near faults are the essential ways for developing oil and gas pools in red bed.

Key words: eastern China, red detrital laterite strata, oil-gas pool, sedimentary structure, reservoir trap, pool-forming regularity
