石炭系已在为川东地区天然气主力产层，为了实现“少投入，多产出”，提高综合勘探效益，必须选择合理的完井方法。既要根据纵向各层的地质特征，有利于减小钻井，完井过程中的风险系数，有利于保护油气层，又要注重完井的质量，有利于试不同、修井、开有等作业，从长远的经济效益和社会效益综合考虑。文章根据川东地区石炭系及其以上地层的特征，压力分布，并对石炭系的各种完井方法进行分析，探讨了适合川东地区石炭系储层的最佳完

STUDY ON COMPLETION METHOD IN CARBONIFEROUS IN EAST SICHUAN AREA

Carboniferous is the main production pay in East Sichuan area. So the reasonable completion method must be choosed to raise the synthetical explorins benefit. According to the strata characters of Carboniferous in East Sichuan and its pressure distribution, the best completion is discussed by analysising all kinds of completion methods. Factors and countermeasures of effecting the best completion are also discussed.
