摘　　要：为了认识塔里木盆地台盆区志留系储层特征及其油气藏成藏主控因素,利用叠合盆地油气功能要素组合-构造过程叠合-相势耦合控油气成藏的新方法,分析该层系18口钻探失利井原因.结果表明:50%的探井因油气成藏功能要素不全或不能有效组合而失利,6%的探井因油气藏遭受后期构造运动被调整、破坏而失利,44%的探井因晚期相势不能有效复合而失利.该研究能够加深认识塔里木盆地油气分布预测的复杂性,检验新方法分析钻探井失利原因的有效性,及其在油气勘探过程中的指导性、对油气勘探区预测的可行性.In order to recognize the Silurian stratum and the features of its reservoir, analysis has been made about the causes of the failures and how to improve the success rate of exploration wells. In this paper, the causes were analyzed according to the new analytical methods of superimposed basins, which include the theory of hydrocarbon accumulation and reservoir system and the new method-multi-factor recombination, procession superimposition; facies-potential combination-predicting oil and gas distribution. The results of the study indicate that the causes of 50% of failure wells result from the lack of multi-factor recombination or effective combination, 6% are adjusted, damaged and lost due to later tectonic movements, and 44% are due to the late ineffective facies-potential combination. This paper has not only further studied the complexity of oil and gas distribution prediction, but also examined the effectiveness of new reservoir theory and predicting method for failure well analysis, the instructiveness to oil and gas exploration and the feasibility to favorable exploration belts prediction.
