Abstract

Abstract:

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 proivdes 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.

Key words: horizontal well, well completion, external casing packer (ECP), bottom water coning, water plugging
