摘要

摘要: 运用气藏地球化学研究方法,对安平1井、高科1井的储层沥青生物标志化合物特征、天然气非烃组分、甲烷碳同位素特征进行了研究,认为安平店-高石梯地区的油源和气源均来自下寒武统筇竹寺组泥岩.并结合区域构造发展史和岩石薄片等基础地质研究,提出了该区震旦系的油气成藏模式,指出安平店-高石梯构造具有较好的天然气勘探前景,主要产层应为震旦系灯影组四段.要找到具有工业价值的天然气,其关键在于寻找好的储层,应避开沥青封堵带打井.

Abstract: Characteristics of natural gas and reservoir bitumen in the area of Anpingdian-Gaoshiti have been studied by means of gas reservoir,and it is concluded that,source of oil and gas is mudstone in the Qiongzhusi group of Cambrian.Combined with history of regional structure and thin-section analysis,it is suggested that,there are 4 periods of oil and gas accumulation.It is also pointed out that,exploration potential of natural gas in the 4th section of Dengying group of Sinian in the Anpingdian-Gaoshiti area is good,and the key of drilling is to find good reservoir and to avoid drilling on the belt of bitumen seal.
