本文根据东濮凹陷地震、钻井勘探资料,从以下四个方面阐述了聚集油、气模式及其有关问题。 1.东濮凹陷具有南北分块,东西分带的地质构造特点及油、气的成带分布规律。 2.对在东濮凹陷内所发现的构造圈闭模式和隐蔽圈闭模式,从它们的成因、形态特点,生、储、盖、遮条件以及与聚集油、气的关系进行了分析。 3.凹陷里的断层活动主要有三期;北北东至北东向断层控制油、气的聚集;早期活动强,晚期活动减弱的断层有利于聚集油、气。 4.根据东濮凹陷内储集层和盖层的各种配置关系,将凹陷内的储盖组合形式划分为五类。结合实例阐述了各种储盖组合与不同类型断块的配置对断块的圈闭性及对断块聚集油、气的重要作用。
Based on the data of earthquakes and drilling exploration in Dongpu Depression, the paper discusses the oil and gas accumulation patterns and their related problems from the following four aspects. 1. Dongpu depression with north-south block, east-west division of the geological structure and oil and gas into the belt distribution. The structural traps and hidden traps discovered in Dongpu sag are analyzed from their genesis, morphological characteristics, genesis, storage, cover and cover conditions, as well as their relationship with oil and gas accumulation. 3. There are mainly three faults in the depression; North-East-North-East fault control the accumulation of oil and gas; faults with early activity and weakened activity in late stage are good for oil and gas accumulation. According to the various dispositions of reservoirs and caprocks in Dongpu sag, the reservoir-cap combination forms in the sag are divided into five categories. Combining with the example, the disposition of various kinds of reservoir-cap combination and different types of fault blocks are described, which is of great importance to the trapping of the fault blocks and the accumulation of oil and gas on the fault blocks.
