对油基超细水泥封堵封窜的认识与实践

THE STUDY ON PLUGGING OF DIESEL-OIL CEMENT

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129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、薄夹层封堵和层内选择性封堵等方面具有良好的堵水不堵油特性。

Abstract: 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 adopt
