摘要/Abstract

摘要： 古近系沙河街组是惠民凹陷最重要的生油层系,该凹陷主要由临南、滋镇、阳信、里则镇等次级洼陷组成。由于沉积过程的差异性,导致形成了各洼陷不同的生烃环境和生烃潜力。其中临南洼陷沉积厚度大,而且有利于烃源岩发育的沙四段和沙三段沉积厚度也较大,属于持续沉降- 深埋藏型洼陷,在其周围形成了大规模的油气聚集。而阳信、滋镇和里则镇虽然也发育了一定厚度的沙四段和沙三段泥质岩沉积,但由于后期沉降逐渐减慢,整个地层埋藏较浅,生烃作用缓慢,在这些洼陷周围仅零星发现有低成熟或未成熟油气,该类洼陷属于逐渐抬升- 中、浅埋藏型。由于临南洼陷充填演化的阶段性和多旋回性,形成了多套富含有机质的烃源岩层。油源对比表明,目前发现的原油均来自沙三段烃源岩,而富含有机质的沙四上亚段烃源岩虽然埋藏较深、成熟度较高,但是目前尚未发现来自该源岩的油气藏。因此,沙四上烃源岩应成为今后油气勘探的一个重要方向。

Abstract: Shahejie formation of Paleogene is the most important source rock in Huimin sag which is divided into sub-sags of Linnan, Zizheng, Yangxin, Lizezheng. The differences of these sags' depositions lead to their different environments and potentials for hydrocarbon generation. Linnan sub-sag is in big thickness of deposition, which is favorable for source rock evolution such as Sha-3 and Sha-4 sections, belonging to stable subsiding or deep buried type, around which there exist large scale hydrocarbon accumulations; while Xinyang, Zizheng and Lizezheng are in relatively shallow buried depth due to late slowing subsiding of pelitic rock deposits in certain depth of Sha-3 and Sha-4 sections, belonging to gradually rising and mid-shallow buried type, and their slower hydrocarbon-generation evolutions allow scattered low mature or immature hydrocarbons to be found around them. It is the episodic and multi-cycle features of sedimentation and evolution in Linnan sub-sag that form multi-set source rocks with rich organic matters. The correlation among the oil sources shows that producing crude oil just comes from Sha-3 source rock. The upper section of Sha-4 source rock is in deep buried depth and high maturity, but related oil-gas reservoirs are not found up to now. Hence, the upper section of Sha-4 source rock should be as an important target for petroleum exploration in future here.

Key words: Huimin sag, evolution, hydrocarbon generation, source rock
