Title: STUDY ON EOR BY HORIZONTALWELLS IN NV34 FAULT-BLOCK
Abstract: Nv34 fault-block is typical of the low permeability reservoir of Shenvsi oilfield in Dagang. Because of the anisotropy, the injection had water fingering seriously and it became second bottom-water. To improve development effects by horizontal wells two more horizontal wells were drilled in 1997. There are straight-wells and horizontal wells in the injection-production unit of Nv34 fault-block. The horizontal wells produce oil, while the straight-wells inject water. This is an effective way for improving development effects and enhancing oil recovery.
