坨142断块含水上升影响因素分析及控制措施

t present the Tuo142 block’s water cut has reached 74%,the rate of oil production is 3.19%, entered the rate of oil production is high, water cut rises a quicker phase of exploitation.This article water cut the rise influence factor in view of the T142 block carries on the analysis, thought causes this block to water cut primary factor which the rise sped up includes strong heterogeneity, structure high inferior static state factor as well as plane pressure is not balanced, formation pressure is low, fluid production intension is big and so on dynamic factor influence. proposed mainly adopted enhances Injection-to-production ratio to restores formation pressure and not stably injects water as well as the water shot-off accent splits and so on the way slows down the block water cut the ascending velocity counter measure measure, and obtained the certain effect.
