摘要

根据地震、录井、测井分析表明 ,松辽盆地北部的西部断陷带营城组发育的沉积体系有扇三角洲、湖泊、湖底扇和火山岩 ;在平面上 ,靠近沉积区边界发育裙带状扇三角洲沉积体系 ,其中夹有大量的火山岩 ;沉积区中央部位为大片的湖泊体系沉积 ,以深湖 -半深湖沉积为主 ,在深湖 -半深湖沉积区发育有湖底扇 .这一沉积特征展示了松辽盆地北部的西部断陷带营城组生、储、盖层均十分发育 ,具有良好的油气勘探前景 .
Based on a large amount of data of core, log and seism, and using the newest methods of sedimentology, this paper clarified the characteristics of sedimentology of Yingcheng Formation in western fault basins belt of North Songliao Basin. There are fan delta depositional system, lacustrine and lake-floor fan system and also volcanic facies developed in the fault basins. Fan delta depositional systems were developed along the margin fault; toward the basin, lacustrine system was developed, specially, deep lake facies were developed very well in north part; and in the deep lake area near the fan delta, lake floor fan was developed. These kinds of characteristics of sedimentology reveal the favorable conditions of source rock, reservoir and seal rock and the favorable potential of oil and gas exploration.
