Abstract

Abstract: The average permeability of block Wei-2 is (6.1~13.5) ×10-3μm², it is a comparatively integral low and super-low permeability reservoir. In the process of developing block Wei2, we took advantage of various development technologies, including reasonable development well pattern, synchronous water injection and oil production, improving injection-production system continually, intensifying adjustment and control of injection-production and reservoir stimulation. From the beginning of development, the field maintains a very good situation of high and stable productivity. The recovery velocity keeps at 1.9%~2.0% in five years, the comprehensive water cut is well controlled below 18% and all kinds of development indexes are significantly better that what they are in development plan.This paper mainly aims at introducing the measures to attainhigh-velocity and high-efficiency development at block wei-2
and the effect.

Key words: block Wei-2, low permeability, synchronous injection-production, high-velocity and high-efficiency, development technology, effectiveness
