Abstract:  Shengli Oilfield has been developed over 50years, the downwhole environment has been increasingly complicated. Therefore, the produce requirement of the residual oil rhythm layer and the low permeability & difficult production reservoir must be in excellent cementing quality, especially for the interfacial cementing quality. In order to improve the interfacial cementing quality, the new type mud cake scraper had been developed as a patented product on the basis of the research on the similar foreign cementing tools. Field application results showed that mud cake scraper could effectively remove the empty filter cake and improve the cementing quality between cement and wellbore . So far, the mud cake scraper has been popularized energetically in the Shengli Oilfield.

摘要：  胜利油田经过 ５０多年的开发，井下变得越来越复杂，剩余油韵律层和低渗透难动用油藏的开采要求 必须具有良好的固井质量，特别是第二界面的固井质量非常重要。为搞好二界面固井质量，在研究国外产品的基 础上，研究开发了一种专利产品—泥饼刮削器，采用独特设计、独特工艺、独特材料，可以有效清除井壁上的虚泥 饼，有利于水泥与井壁的胶结，经过现场实验、应用，效果非常好。目前，已经在胜利油田大力推广，二界面固井质 量大大提高。
