摘要:
川西中层水平井目的层为沙溪庙组，因地表限制多为小偏移距中曲率半径三维水平井，存在地层稳定性差、造斜点深、井眼轨迹控制难度大等特点，首轮次钻井施工因增斜井段不规律交错的砂泥岩失稳垮塌，造成井下摩阻和扭矩增大、水平段钻进困难等问题。为减少复杂时效、缩短施工周期，对施工井轨迹按直井段、增斜段、水平段进行了分段优化，形成了一套适合川西中层水平井的井眼轨迹控制技术。该技术在7口井进行了应用，平均钻井周期由127.86 d降至59.63 d，平均机械钻速由5.37 m/h提高至8.95 m/h。
Abstract:
The target layer of middle-level horizontal wells in Western Sichuan is the Shaximiao Formation. Due to surface constraints，most of the horizontal wells are three-dimensional horizontal wells with a slight offset and medium radius of curvature，which are characterized by poor formation stability，depth deviation point，and difficulty in controlling the trajectory of the borehole. In the first round of drilling construction，the instability and collapse of irregularly intersecting sand and mudstone in deviated well sections caused downhole friction，torque increase，and difficulties in horizontal section drilling. In order to reduce the complicated time and shorten the construction period，the construction well trajectory was optimized in segments according to the straight section，increased slope section，and horizontal section，and a set of borehole trajectory control technology suitable for mid-level horizontal wells in Western Sichuan was formed. The technology was applied in 7 wells，reducing the average drilling cycle from 127.86 days to 59.63 days and increasing the average penetration rate from 5.37m/h to 8.95m/h.
