摘　　要：注水泥是固井过程中的重要环节,水泥层间封隔质量的好坏直接影响到油气田安全合理的开发以及后继开采的正常进行。通过排查各种可能因素,如水泥浆的密度、失水性、稳定性等,具体分析水泥浆性能、水泥石性能以及各种地层因素、人为因素对水泥层间封隔质量的影响,对水泥环与套管、地层间出现微间隙以及油、气、水相窜流的可能原因进行了分析和探究,为综合评价水泥的层间封隔质量提供了一些思路。Cementing is an important link in oilfield development,whose main purpose is to realize the zone isolation which directly affects development and subsequent exploitation in oilfield.Through analyzing kinds of possible factors,like slurry density,fluid loss property and stability,the impacts exerted by slurry performances,cement stone performances,various formation factors and human elements on the quality of zone isolation have been measured,and the reason for why the fluid channeling in the well and micro-gap between cement sheath and casing pipe occur have been carefully studied,both of which will help people comprehensively evaluate the cement quality concerning the zone isolation.
