钻井事故、复杂情况分析自１９８３年１月硐西１井开钻以来，截至１９９７年１０月底完成井２９口，该区钻井技术指标与川东地区“八五”期间已钻的１１２口井平均技术指标统计相比，平均建井周期多８０ｄ，平均机械钻速为１．２２ｍ／ｈ，较１１２口井机械钻速１．４３ｍ／ｈ?
Drilling Accident and Complicated Situation Analysis Since the drilling of the borehole in West Jiangxi in January 1983, 29 wells have been completed by the end of October 1997. The drilling technical indicators of this area are in line with the average of 112 wells drilled during the “Eighth Five-Year Plan” period in eastern Sichuan Compared with the technical indicators, the average well-drilling cycle is 80d more and the average penetration rate is 1.22m / h, which is 1.43m / h higher than that of 112 wells.
