石炭系是塔里木盆地台盆区油气勘探潜力巨大的层位之一，成藏条件复杂。为了探明塔里木盆地台盆区石炭系有利勘探区域，提高探井成功率，文中利用油气功能要素组合-构造过程叠合-相势耦合的新方法，对塔里木盆地台盆区石炭系的29口成功井和49口失利井进行了原因剖析。研究结果表明，所有成功井均位于功能要素有效组合-弱弱构造过程叠合-优相低势的范围内，失利井中10%的探井因功能要素不全或不能有效组合而失利，18%的失利井由于油气藏遭受后期构造运动被调整、破坏，72%的探井则是由于晚期相势不能有效复合。本研究加深认识了塔里木盆地油气成藏和分布的复杂性、表明了新方法分析探井成功与失利原因的有效性，对油气勘探具有一定的指导意义。

Carboniferous strata is one of the series of strata with the most oil and gas exploration potential in Tarim Basin and its conditions of hydrocarbon accumulation are complicated. In order to identify the favorable exploration areas and increase the success rate of exploration wells in the Carboniferous strata of Tarim Basin, the reasons of 29 successful wells and 49 failed wells of Carboniferous strata in Tarim Basin were analyzed in this paper using the new analytical methods of superimposed basins, which include the multi-factor recombination, tectonic process superimposition, and facies-potential combination. This study indicates that all the successful wells are in the regions where they have the effective multi-factor recombination and weak tectonic superimposition and good facies and low potential. The reason for 10%of failed wells is the lack of multi-factor recombination or effective combination;18%of failed wells are due to later tectonic movements that destroyed flve reservior, and 72%are due to the late ineffective facies-potential combination. This paper has not only further studied the complexity of oil and gas accumulation and distribution,but also examined the effectiveness of new analytical method to failed wells analysis. The results have positive guiding significance to oil-gas exploration.
