In high-inclination drilling, cuttings easily accumulate in the section of 40-60 °inclination angle and form cuttings beds which lead to accidents of bit bouncing and drill pipe sticking.
大斜度钻井过程中,钻屑在40～60°井段易堆积形成岩屑床,对井下安全危害极大,容易引发憋钻和卡钻事故。
3) cuttings bed
岩屑床
1.
The problem on cuttings bed accumulated easily by cuttings particle at low boundary of well wall in high angle deviated well and horizontal well while drilling in Jidong Oilfield,results in underground troubles and influencing subsequent operation.
针对冀东油田在大斜度井及水平井钻井过程中岩屑颗粒易在井壁低边堆积形成岩屑床、造成井下复杂情况并影响后续作业这一问题,对井下环空岩屑床形成与否及厚度大小、影响钻井液携岩效果的主要因素如井斜角、钻井液环空返速及性能、钻杆偏心及旋转等问题进行了研究,建立了环空岩屑床厚度计算模式,并用该模式对冀东油田高104-5平56井进行了具体分析。
