由于小井眼井井身结构复杂、井眼尺寸小等特殊性,挤水泥封堵窜层、挤水泥封堵水层、机械卡封水层等常规修井工艺和增产措施变得异常复杂,成功率低,成本高。主要表现在:工具难配套,修井工艺复杂、不易控制等特点。为了解决这一难题,近年来通过研究和现场实验,在成功研制了小井眼系列小桥塞基础上,发展了小直径插管采油技术。 Because of the special structure of slim well borehole and small borehole size, conventional workover techniques and stimulation measures such as plugging cement by water plugging, plugging water layer by squeezing cement, water seal by mechanical seal, etc. have become extremely complicated and successful Low rate, high cost. Mainly in: difficult to support tools, workover technology complex, difficult to control and so on. In order to solve this problem, in recent years through the research and field experiments, the successful development of a series of small borehole bridge plug on the basis of the development of small diameter intubation production technology.
