摘要: 固井质量对干热岩后期开发利用具有重要意义。针对山西大同盆地干热岩勘查井GR1井温度高、高温固井水泥浆技术体系不完善等问题，通过研究勘查区地质特征，提出了高温固井水泥浆技术体系开发思路。研究表明：干热岩高温固井水泥浆水胶比控制为0.45，优选添加剂高温降失水剂CG82L、高温缓凝剂H40L、高温稳定剂CF40L、消泡剂GX-1、硅粉及HV-PAC，形成一套适用于山西干热岩井的高温固井水泥浆技术体系。该水泥浆体系在GR1井成功应用，现场固井质量良好，研究成果为今后同类型高温固井工作提供了宝贵经验和技术支撑。Abstract: Cementing quality plays an important role in the later development and utilization of hot dry rock. In view of the problems of high temperature and the incomplete technical system of high temperature cement in hot dry rock exploration Well GR1 in Datong Basin， this paper presents the approach to the development of the high temperature cement slurry technology system through investigation of the geological characteristics of the exploration area and the cementing experience on hot dry rock wells at home and abroad. The results show that the high temperature cementing slurry system which is suitable for Shanxi high temperature dry hot rock wells can be created with the water-gel ratio of high-temperature cementing slurry for hot dry rock wells at 0.45， and the preferred additive of high temperature water loss reducer CG82L， high temperature retarder H40L， high temperature stabilizer CF40L， defoaming agent GX-1， and silicon powder and HV-PAC. The cement slurry system has been successfully applied in Shanxi high temperature hot dry rock Well GR1， and the field cementing quality was good. The research results provide valuable experience and technical support for the same type of high-temperature cementing work in the future.
