摘要:
许X36A井是下扬子古生界逆断块高部位的一口侧钻评价井,井深大、裸眼段长、轨道复杂且井斜位移大,所钻遇地层跨度大,岩性硬脆、可钻性差、研磨性高。钻进施工中摩阻扭矩大,机械钻速低,井壁易失稳,井眼清洁困难,易出现钻具故障,存在诸多难点。为此,从井身轨迹控制出发,优化剖面,适当降低最大井斜角,优选小角度单弯,以降低摩阻;优选七刀翼钻头,应用旋冲螺杆提速工艺,以提高机械转速;针对不同的井段特点优选钻井液体系并适时进行性能维护;针对井下复杂故障,采取了相应的预防与处理措施。许X36A井钻探获得成功。
Abstract:
Well XuX36A is a sidetracking evaluation well in the high part of the lower Yangtze Paleozoic reverse fault block. It has a large well depth,a long open hole section,a complex track,and a large deviation displacement. The drilled strata has a large span,hard and brittle lithology,poor drillability and high abrasiveness.During the drilling operation,there are many difficulties,such as the difficulty of friction torque control,the instability of well wall,the difficulty of hole cleaning,the low rate of mechanical drilling,the failure of drilling tools and the high-quality requirements for drilling tools. For this reason,starting from the well trajectory control,optimizing the profile,appropriately reducing the maximum inclination angle,and preferring a small angle single bend to reduce friction; optimizing seven-blade wing bit,and using rotary screw speed-up technology to increase mechanical speed; according to the characteristics of different well sections,the drilling fluid system was optimized and performance maintenance was carried out in a timely manner; corresponding preventive and handling measures were taken for complex downhole faults. Drilling of Well Xu X36A was successful.
