摘要: 为了进一步完善超短半径水平井钻完井技术,提高单井产油量,大庆油田设计施工了茂加65-82双分支超短半径水平井。针对2个分支井眼曲率半径不一致导致井眼轨迹控制难度大、分支井眼与窗口密封难度大等技术难点,根据茂加65-82井原井眼情况,对双分支水平井眼的井身结构、井眼轨道进行了优化设计,并在钻头体与导向管之间设计了倾角,以满足造斜要求,顺利完成了曲率半径分别为5.9和3.2 m的上下分支水平井眼,井眼轨迹达到了设计要求。茂加65-82侧钻双分支水平井初期日产油量2.5 t,与原井产油量相比提高了8.3倍,目前日产油量1.0 t,已累计增油380 t。茂加65-82双分支超短半径水平井的顺利钻成为大庆油田剩余油挖潜提供了一种新的技术手段。Abstract: To further improve ultra-short radius horizontal well technology, the Daqing Oilfield team designed a two-lateral ultra-short radius horizontal well for Maojia 65-82. They designed it with two branches to improve the yield of a single well. In order to overcome the difficulties of well trajectory control and difficulties of sealing branch holes and windows due to different curvature radius in the two branched holes, the inclination angles between the drill bit and the guide pipe were designed to meet the requirement of buildup. They combined the optimum design for the casing program which was completed incorporating well profiles and well trajectory optimum design based on the original borehole conditions of the well. As a result, the upper and lower branches with radius of curvatures of 5.9 m and 3.2 m were completed successfully in the Well Maojia 65-82. The initial daily oil production in the Maojia 65-82 was 2.5 t, which is 8.3 times higher than that of the original borehole. At present, daily oil production is 1.0 t and cumulative oil production is 380 t. The completion of the multilateral ultra-short radius horizontal well Maojia 65-82 with two branches may provide a new method for exploitation of residual oil in the Daqing Oilfield.
