提高扎纳诺尔油田钻井速度的试验研究

扎纳诺尔油田是中国石油在哈萨克斯坦共和国购买的2个油田(扎纳诺尔和肯基亚克)之一,中国石油具有20年的开采权限,因此,提高钻井速度成为迫切需要解决的问题。在收集和分析了扎纳诺尔油田70余口已钻井资料基础上,对地层岩石的可钻性和钻头优选进行了研究后认为,提高扎纳诺尔油田钻井速度的关键是提高?215.9mm井眼的钻速。先后在3500井KT-1盖层和KT-2盖层进行了2次现场试验,机械钻速均有较大幅度提高。试验结果表明,采用井下动力钻具~转盘复合钻井技术,配合优质高效PDC钻头和高速牙轮钻头钻进,可

Experimentation Research of Improving the Drilling Rate of Zhananuoer Oilfield

For the sake of as early as possible realizing 1 target that one drilling machine could drill three wells per year in the Kazakhstan Zhananuoer oilfield,this text considers that the key to increase the drilling speed is increasing the drilling speed of ?215.9mm segment on the base of collecting and analyzing the information of 70 wells and researching the performance of drilling ability of stratum and the excellent choosing of bit.Twice local experimentaion has been processed at KT-1 covering floor and KT-2 covering floor in 3500 well,and penetrating speed has been increased great high.This text considers that it is possible to increase great high the penetrating speed of Zhananuoer oilfield and realize drilling more well after adopting down-hole motor and turntable compound drilling technique and concerting good high effect PDC bit and high speed roller bit.
