川东石炭系气层完井液损害研究

A Study of Completion Fluid Damage to Gas-Bearing Forma- tions of Carboniferous in East Sichuan

本文采用流动模拟实验方法,以渗透率损害率为评价气层损害的定量标准,对以川东石炭系为主的完井液损害程度及滤失深度进行了试验研究,并对地层损害进行了预测。

In this paper, the degree of damage and depth of filtration of the completion fluid used mostly in Carboniferous in Fast Sichuan are experimented and analyzed and the formation damage is forecasted by using flow analogy experimental method and making permeability damage rate as the quantitative standard for evaluating the damage of gas-bearing formations.
