哈萨克斯坦肯基亚克油田地层古老,夹层较多,可钻性差,在钻进过程中蹩跳钻严重,钻头使用寿命受到严重影响,不仅需要频繁起钻更换钻头,且断钻具及钻头事故时有发生。为此,经应用实验,采用水力加压器对钻头及钻具进行减震保护,改善钻头工作状态,提高钻头和钻具使用时间,解决蹩跳钻等问题,试验结果表明使用水力加压器可极大提高机械钻速,缩短建井周期,避免井下事故,节省钻井成本,故应加大水力加压器在该油区的使用范围。
KazakhstanKankyak oil field ancient strata, more interlayer, poor drillability, drills in the process of drilling a serious cramp, bit life is seriously affected, not only frequent drill replacement drill, and broken drill and drill accident happens sometimes. To this end, the application of experiments, the use of hydraulic pressure drill bit and drill shock absorption and protection to improve the working status of the bit, bit and drill to improve the use of time, to solve the problem of bad jumped into the drill, the test results show that the use of hydraulic pressure device Can greatly improve the rate of penetration, shorten the period of well construction, avoid underground accidents, save drilling costs, it should increase the hydraulic pressure in the area of ?? use.
