摘要
顺托果勒 -满加尔地区勘探程度相对较低 ,通过对地震资料的解释分析 ,结合钻井、地表露头资料初步查明了寒武 -奥陶系的沉积特征及其与烃源岩发育的关系。其中寒武系 -下奥陶统主要为欠补偿的半深海盆地 -斜坡 -台地边缘 -碳酸盐岩台地沉积 ,有利于烃源岩发育 ,特别是半深海盆地及斜坡相沉积。中上奥陶统则为超补偿的半深海盆地 (以厚度巨大的浊积岩为特征 ) -混积陆棚沉积 ,总体不利于烃源岩发育。
The level of geological exploration in Shu ntuoguo le-Manjaer area is lower relatively.It has been found out for sedime ntary character of Cambrian-Ordovician system and it`s relations with the devel opment of hydrocarbon source rock by explanation and analysis of seismi c data and outcrep information. Cambrian-low Ordovicion is mainly under compe nsational sediment of bathyal basin-slope-platform edge-carbonate platform.It is favourable for the development of hydrocarbon source rock.Especially bathyal basin and slope facies deposit.Middle-late Ordovician is super-compensatio nal bathyal basin (it`s feature is turbidite) and mixed continental shelf deposit.It is not favourable for the development of hydrocarbon source rock.
