【摘要】 目前解决固井漏失主要有两种方法：一种是采用双级或多级注水泥；另一种是采用减轻剂降低水泥浆密度。前者不仅施工比较复杂，而且占用的钻井时间长；后者则是研究应用的方向，但在有效强度范围内多数减轻剂的密度降低极限值仍较高，不能满足有些地层的要求。针对吐哈油田固井实际选用了漂珠减轻剂，经过２２口井的固井实践，表明该技术工艺简单、施工方便，并能解决低压是漏失与全井段封固的矛盾，具有良好的技术经济效果及应用前景。更多还原

【Abstract】 The cementing technique with drift Pearl light weight cement is able to resolve the contradictions between low pressure face leakage and total well bore sealing. It was proved by the practical application of 22 wells in Tuha oil field for cementing operations that the technique is simple, convenient and has favourable technique-economic result and applied potential.更多还原
