2000 m地热井用套管的研制

Development of Casing for 2000m Geothermal Well

摘要:

随着近年来地热井施工的不断发展，地热井用套管的需求量稳定增加。与此同时，原来使用石油套管的地热井施工成本也在不断攀升，急需研制一种地热井专用套管，以适应地热井施工降低成本的需求。因此，根据地热井施工特点和对套管的性能要求情况，研制了一种低成本地热井专用套管。主要介绍了该套管的结构形式、技术参数、工艺装备以及生产试用情况。

Abstract:

With the continuous development of the geothermal well construction in recent years, the demand of casing for geothermal well is also increasing steadily. Because the construction cost of geothermal well using oil casing keeps growing, it is urgent to develop a special casing for geothermal well to adapt the needs of geothermal well construction with low cost. According to the characteristics of the geothermal well construction and the performance requirements to the casing, a low-cost casing for thermal well is developed. The paper mainly introduces this casing about its structure form, technical parameters, process equipment and production application.
