摘要
油基超细水泥是一种选择性堵剂。在室内考察了油基水泥浆的分散剂含量、油灰比、凝结时间等因素对封堵效果的影响 ,结合多种测井手段 ,通过在王 1 2 9等 4口井的现场试用证明 ,油基超细水泥在油井套管外窜封堵。
As a selective water shutoff agent, diesel-oil cement has the characteristic of plugging water without plugging oil. Based on the lab evaluation of diesel-oil cement on disperer, oil-cement ratio, condensating time, etc.,various logging methods were adopted to evaluate the plugging external casing channeling, thin intermediat layer and internal selective plugging. The site test result showed that the diesel-oil cement has a good properties to plug water not oil.
