摘要
针对丛式三维水平井轨迹控制精度高、井筒间的防碰设计难、管串下入摩阻大等难题开展攻关与实践,并在长庆油田庄230井区林平35-1井组进行了先导性现场试验,成功实施突破了丛式三维水平井井间防碰、井眼轨迹控制瓶颈技术难题,形成了以井身结构优化、井网布局优化、剖面轨迹控制等技术集成配套的丛式三维水平井井组整体设计。
For tackling the technological difficulties such as the high required precision of trajectory control, wellbore anti-collision design, and the large friction of string tripping existing in cluster 3D horizontal well, a pilot field test was carried on in Linping 35-1 well group of Zhuang 230 area, and a successful breakthrough was made. Thus, an overall design integrating the technologies of casing program optimization, pattern distribution optimization, with profile trajectory control for well group of cluster 3D horizontal well has been formed.
