在油田开发过程中,由于地质、工程等原因,越来越多的油(气、注水)井成为废弃、闲置井。侧钻井工艺技术作为一种充分利用油田废弃、闲置井挖掘老油田现有油气藏潜力、对老油田进行二次或三次采油、提高原油采收率的经济有效的方法,正越来越受到国内外油田的重视。目前国内外普遍采用该工艺技术对有价值的老井进行开窗侧钻,实现“二次井网”对剩余油的充分控制。侧钻井技术有着极大的发展前景和推广价值。 In the process of oilfield development, more and more oil (gas and water injection) wells become abandoned and idle wells due to geological and engineering reasons. As a economical and effective way to make full use of abandoned and idle wells in existing oil and gas reservoirs in old oilfields, it is more and more economical and effective to carry out secondary or tertiary recovery of old oilfields to enhance oil recovery. Outside the field of attention. At present, the technology commonly used at home and abroad to open the valuable old wells sidetracking, to achieve “second well pattern” of the remaining oil full control. Side drilling technology has great prospects for development and promotion.
