摘要
针对底水油田水平井开发存在的底水锥进和后期堵水两个重要问题进行了能够延缓和控制底水锥进的完井方法研究,提出了采用两端套有ECP的盲管与筛管间隔排列方式,并利用ECP封隔井眼环空和采用长盲管段延缓底水锥进和方便层段封隔的完井方法,为合理开发底水油田提供了一套新的思路和配套的完井方法。已经在中国南海生物礁灰岩地层的大位移水平井中获得应用。
A new-type horizontal well completion method of delaying and controlling bottom water coning is developed because of the two problems of bottom water coning and water plugging later in bottom water oil fields.and the new well completion method adopts the mode of arrangement of intervals of blank tubing with ECP in the two ends and screened pipe,which seals off well annulus by ECP,delayes bottom water coning by long blank tubing,and conveniently seals off intervals,and provides a new train of thought and forms a complete well completion system for developing the bottom water oil fields of the reef limestone in extended-reach horizontal well completion in South China Sea reasonably.
