摘要：针对中江构造丛式井组井间防避压力高、轨连控制难度大及钻并周期长等难题，借鉴国内外页岩气藏“井工厂"轨逆控制技术成功经验，研究形成了以槽口-靶点优化布置、“多增式”并眼轨道设计、直并段防斜打快及并间防碰为核心的致密砂岩气藏“井工厂”钻井井眼执迹控制技术，并首次将该技术应用到JS33-19HF平台6口并开发中。现场应用表明，优化后的轨道设计及轨连控制技术保障了并身质量、提高了机械钻建，并组平均机械钻速较设计提高了54.1%，实际钻井周期缩短 102.47d。该技术的成功应用对致密砂常气减的高效开发具有重要借鉴意义。

Abstraet: The cluster well group in Zhongjiang structure is faced with a series of difficulties, e.g. stressful interwell anti-collision, difficult trajectory control and long drilling cycle. To deal with these difficulties, the “well factory" trajectory control technology for tight sandstone gas reservoirs was developed referring to domestic and foreign successful experience of*well factory" trajectory control technologies for shale gas reservoirs. This technology takes notch-target point arrangement optimization, "multi-increase" borehole trajectory design, deviation control and fast dilling of vertical hole section and interwell anti-collision as the core. This technology was for the first time applied to the development of 6 wells on JS33-19HF pad. It is indicated that based on the optimized trajectory design and the trajectory control technology, wellbore quality is guaranteed and rate of penetration (ROP) is increased. Average ROP of the well group is 54.1% higher than the designed value and the drilling cycle is actually shortened by 102.47 d. The successful application a o e e sed sa ses o aee a development of tight sandstone gas reservoirs.

中江气田主力储层沙溪庙组埋深变化大(1700~2700m),平均孔隙度8.5%，平均渗透率0.21 mD，属典型的致密砂岩气藏。截至2015年9月，中江气田已钻沙溪庙组水平井116口，平均完钻井深 3335.88m，平均钻井周期52.29d。在钻探过程中
受到轨迹控制困难、钻井速度慢的制约，综合效益极低。为此需要进一步降低钻井综合成本，寻求一种“工厂化”的开发模式[14]。2015年底，中石化西南油气分公司在中江气田首次开展了“井工厂”钻井模式开发叠置河道致密砂岩气藏的探索和试验
