| 摘 要： | 浅层丛式水平井技术是吉林油田扶余地区完善井网、高效开采的有效手段，而浅层丛式水平井的井眼轨迹控制是其成功实施的关键技术。通过对吉林油田扶余城区12号丛式水平井组井口间距小、井浅、井多等技术难点的系统分析研究及现场钻井试验总结，形成了一套完善的浅层丛式水平井井眼轨迹控制技术，即优化井口排布、直井段防斜打直、优选造斜点、轨迹误差保守计算、优化钻具组合、提高轨迹测量精度、有效防碰绕障和精细施工等。并利用该技术在扶余城区12号丛式水平井组顺利实施32口井(其中水平井23口，大位移定向井8口，直井1口)，创下国内单个平台水平井数量最多的纪录。现场应用表明，浅层丛式水平井技术可成功解决因井场征地困难、地面受限等原因造成的储量难动用问题，为扶余油田受限油藏的集约、有效开发提供了一种新的途径和方法，具有广阔的应用前景。
