钻深井的技术策略

当井泄漏时,技术套管必须承受挤压,井喷和井井必须承受坍塌,因此井的质量必须是高质量的。深井钻井时间长,钻井次数多,技术外壳容易损坏。需要各种措施来保护套管。例如,在套管中不允许使用焊接在接头上的硬质合金的钻杆,并且不允许套管中的钻杆。应在接头上安装橡胶护罩以限制钻头的速度。在满足这些“保持”条件后,必须使用各种方法来“打击”以提高钻孔速度。首先,需要一种新型的PDC钻头和一种热稳定的金刚石钻头来代替滚子钻头,因为深井的形成主要是中等硬度和硬度,并且磨料钻头的使用更好。
打井施工工艺及注意要点

Well drilling c***truction technology and attention points
1. According to the requirements of the water output of the well, the wellbore structure is designed with the well depth and the caliper, and the drilling machine type and the corresponding auxiliary equipment are selected in combination with the stratum.
2. Before drilling, the machine should be leveled, the equipment should be arranged, the equipment should be stored, the tower should be erected, and the rig should be placed.
3. Drilling holes in the bedrock aquifer, *** is better to use rotary core drilling. During the drilling process, hydrogeological observati*** such as groundwater level and the disappearance of circulating liquid holes should be carried out.
4. During the process of drilling into holes, it should be described according to technical requirements, layered soil samples, water samples, temperature measurement, etc. Also ensure the quality and quantity of the sample.

研究岩石的水分含量。岩石按其成因可分为火成岩,变质岩和沉积岩。细分非常复杂。无论原因如何,用锤子敲打的感觉都是“吱吱”(硬),“棉”(柔韧性),“脆”(脆)和更易溶的岩石,如脆性岩石和石灰石。容易成为一口井。研究岩石的断裂发展。断裂断裂带附近的断裂较发育。倾斜的岩石比水平的岩石裂缝更发达。选择适合当地地质条件的地球物理勘探方法
目前,物探方法主要是电法勘探。电检测方法进一步分为人工电场方法和自(日)电场方法。
