摘　　要：针对塔里木盆地中央隆起地带预探区带勘探程度较低、资料较少、定性评价要求准确度较高,导致评价误差大、评价结果不准、非常依靠专家经验,评价难度较大等问题,引入了层次分析法,在预探区资料较少情况下,将定性评价和定量评价方法结合,对塔里木盆地中央隆起带柯坪塔格组地层开展了含油气区带评价研究。对含油气区带评价单元优选6项成藏主控因素、10个评价子项参数,建立塔里木盆地碎屑岩评价体系和标准,通过三标度法构建比较矩阵,引入最优传递矩阵,计算组合权值,建立综合评价模型,优选油气发育有利区。研究表明,研究结果表明:卡塔克隆其东、顺托底凸、顺南斜坡地区具有良好的油气成藏条件,为有利油气富集区。该研究对预探区带的评价、有利区预测以及勘探开发前景具有重要意义,对下一步的油气勘探有重要的指导意义。In view of the central uplift of tarim basin zone preliminary exploration area with low degree of prospecting, less data, high accuracy of qualitative evaluation requirements, result in great error in the evaluation, the evaluation results are not allowed to, very depend on expert experience, evaluation is difficult problem, this paper introduces analytic hierarchy process(ahp), under the condition of less acreage information beforehand, the combination of qualitative evaluation with quantitative evaluation, The oil and gas zone evaluation of the Kepingage Formation in the central uplift belt of Tarim Basin has been carried out. Six main controlling factors and 10 sub-parameters of evaluation were selected for the evaluation unit of oil-bearing area, and the evaluation system and standard of clastic rock in Tarim Basin were established. The comparison matrix was constructed by three-scale method, and the optimal transfer matrix was introduced to calculate the combination weight, and the comprehensive evaluation model was established to optimize the favorable areas for oil and gas development. The results show that the east of Catakelongqi, Shuntuo base-convex and Shunnan slope areas have good conditions for oil and gas accumulation, which are favorable for oil and gas accumulation. This study is of great significance to the evaluation of the pre-exploration zone, the prediction of the favorable area and the prospect of exploration and development, and has important guiding significance for the next step of oil and gas exploration.
