Design and Drilling of Horizontal Well Yuanping 1 with Long Lateral Section

  • 摘要: 为确保大庆油田第一口长水平段水平井垣平1井的安全顺利钻进,开展了该井钻井工程设计方案研究。针对该井水平段较长,钻井过程中存在钻柱易屈曲、摩阻/扭矩大、井眼净化难、套管难以下入等技术难点,运用Landmark软件对不同设计剖面、不同靶前距和井眼曲率下的摩阻/扭矩及钻柱屈曲情况进行了模拟,以模拟结果为基础,设计了该井的井眼轨道;根据Landmark软件模拟钻柱滑动钻进与旋转钻进时的钻柱屈曲情况,对三开水平段钻具组合进行了优化设计;根据钻井参数对岩屑床厚度影响的模拟结果,优化了三开水平段的钻井参数;模拟计算结果表明,采用漂浮接箍下套管工艺能降低下套管时的摩阻和屈曲程度,因此该井三开采用漂浮接箍下套管工艺。该井钻井过程中没有出现井下故障,完井、电测及下套管安全顺利,说明该井工程设计合理,有效克服了钻井过程存在的技术难题。
    Abstract: In order to ensure the safe and smooth drilling of Well Yuanping 1,the first horizontal well with long lateral section,the drilling engineering design of the well was studied.In view of the tricky issues associated with long lateral section such as buckling of drill string,big drag/torque,difficult borehole cleaning and casing running,etc,Landmark software was used to calculate drag/torque and drill string buckling at different design profiles,different target distances and borehole curvatures,and the borehole trajectory was designed based on the simulation results,BHA of the horizontal section on the third spud was optimized based on the drill string buckling in sliding drilling and rotary drilling simulated by Landmark software,and drilling parameters of the horizontal section was optimized based on the simulated effect of drilling parameters on cuttings bed thickness.The simulation results show that running casing with floating sub can reduce friction and buckling,so the technique was adopted in running casing in this well.There were no complexities or accidents in drilling,completion,wireline logging and casing running,indicating that the engineering design is proper,and the technical difficulties in drilling long horizontal section can be overcome.
