摘要
在四川南部凹陷高石梯构造钻探的高科1井在目的层没有找到工业气流。运用气藏地球化学研究方法,对高科1井的天然气特征、储层沥青的生物标志化合物特征进行了研究。结合区域构造发展史和岩石薄片研究综合分析后认为:高科1井的失败主要在于没有找到好的储层,井正好打在了沥青封堵带上;但是,高科1井所在的高石梯构造区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;在该区,要找到具有工业价值的天然气,关键在于寻找好的储层,避开沥青封堵带打井。
The characteristics of natural gas and reservoir bitumen in well Gaoke 1 have been studied by using the geochemical method of gas reservoir. Combining with the history of regional structure and the thin\|section analysis, it is suggested that the bad reservoir has resulted in the failure of well Gaoke 1. In addition, it is pointed out that the exploration potential of natural gas in the fourth section of Dengying group in Sinian in Gaoshiti area is good, and the key of drilling is to find good reservoir and to avoid drilling on the belt of bitumen seal.
