摘要
在分析中原油田文东地区地层特性及钻井中存在的主要难题的基础上,提出了从井身结构、钻具组合、钻井液体系、钻头选型及完井技术几个方面较优化的钻井方案。在该地区几十口调整井钻井中应用表明,机械钻速明显提高,钻井周期缩短,经济效益非常好。
s: Based on analyzing formation characteristics and main drilling problems in Wendong area in Zhongyuan Oilfield, an optimum drilling program is given according to its well configuration, bottom hole assembly, drilling fluid system, bit selection and completion technique. Field applications in several adjustment wells in this area show that the ROP is obviously improved and the drilling cycle is reduced. Its economic benefit is much better.
