Causal Analysis of the Failure of Oil-Gas Exploration Wells of the Carboniferous Platform in Tarim Basin
摘要
Abstract
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.关键词
