哈萨克斯坦PK孔戈尔油田防斜打快技术

Vertical and Fast Drilling Technology in PK Kunger Oilfield,Kazakstan

根据实际地层情况和井身结构,选配了一种反钟摆钻具结构,通过计算推套出该钻具结构下,防斜和降斜钻压经验公式,解决了高钻压提速和防斜相统一的难题,最大程度降低了井下风险,现场使用效果良好。

According to the actual stratum condition and well bore configuration, a type of anti-pendulum drilling tool configuration is selected. Based on the calculation under the condition of anti-pendulum drilling tool configuration, the drilling pressure empirical formulas of preventing wellbore form inclination and dropping inclination are calculated, which resolved the difficulty of unification of fast drilling with high drilling pressure and preventing wellbore from inclination and reduced downhole risk, and field application effect is good.
