The control of the trajectory is the core technique in horizontal well technique , while trajectory design and optimal design are the two key techniques 井眼轨迹控制是侧钻水平井技术的核心,而轨道设计与优化设计又是轨道控制技术的两大关键技术之一。
Field application shows that the section milling efficiency of casing is remarkably improved after taking use of more scientific measures , furthermore , which accelerates speed of sidetracking horizontal well 在辽河油田的现场应用表明,在采用较为科学的操作措施后,套管段铣效率得到了明显提高,从而加快了侧钻水平井的钻井速度。
Taking tk104h well , tk202h well and tk105h well as examples , the paper discuss the main reasons that cause the sticking accidents , and put forward sticking - releasing measures , which is important for the future drilling operations in the area 其中优选出的钻井液性能参数和设计制造的“二次破岩除床器”应用于胜利油田10多口侧钻小眼井的钻井施工中,取得了很好的效果。
In addition , side - tracking in old wells can produce residual oil between wells and on structural high , improve pattern arrangement , and control bottom water coning ; it is an effective method for developing minor fault block reservoir with complex lithology and bottom water 同时,老井侧钻既能挖掘井间及高部位剩余油,完善井网,又能有效控制底水锥进,是复杂底水小断块油藏经济高效开发的措施方法。
