摘要

在固井前有效清除井筒中的泥饼对于形成良好的水泥与地层胶结至关重要。应用隔离剂可以有效去除泥饼。泥饼去除效果的评价对隔离器的设计具有重要意义。学者们提出的方法在泥饼的开发和冲洗过程的模拟方面存在局限性。本文设计了一种新型的泥饼去除效率测试装置。提出了一种新的测定隔离器泥饼去除效率的实验方法。讨论了影响泥饼去除效率的因素。该方法可定量评价冲洗效率，为隔震器的设计提供指导。

A Novel Experimental Method for Mudcake Removal Efficiency of Spacer

Effective removal of mudcake from the wellbore before cementing is critical to developing an excellent bond between cement and formation. The application of spacer can remove mudcake effectively. The evaluation of mudcake removal efficiency is significant to the design of spacer. The methods proposed by scholars have limits on the development of mudcake and the simulation of the flushing process. For this paper, a novel apparatus used to test mudcake removal efficiency was designed. A novel experimental method for mudcake removal efficiency of spacer was proposed. The influence factors of mudcake removal efficiency are discussed. The method can evaluate the flushing efficiency quantitatively and provide guidance for designing of spacer.
