| 摘 要： | 钻孔漏失是煤田钻探常见的复杂问题之一，而水泥浆堵漏是现场使用最多的堵漏方法之一。但在裂缝性地层、洞穴或高渗地层中容易出现水泥浆漏失的难题。将特种纤维引入常规水泥浆体系中，通过室内实验研究纤维水泥浆的堵漏性能、触变性能、流动性能和水泥石的力学性能，并分析其堵漏作用机理，介绍了其在国内外油气钻井和固井领域的应用情况。研究表明，纤维水泥浆在此类地层中具有较好的堵漏效果，在煤田钻探领域将具有良好的应用前景。

| Abstract: | Lost circulation of borehole＇is one of the complex problems in coal bed drilling process and cement slurry sealing is the most commonly used method on site. However, lost circulation of cement slurry often happens in fissured, cave or high permeability formations. The paper introduced special fiber into the conventional cement slurry systems and made research on its sealing performance, rheopecticity, fluidity and mechanical property of cement stone by laboratory experiments. The paper also analyzed the sealing mechanism of fiber cement slurry and the applications of which were introduced in the drilling and cementing processes. The research results demonstrate that fiber cement slurry has good sealing effect in above - mentioned formations and it has a promising future in coal bed drilling fields. |
