定向钻井技术
定向钻井技术是钻井工程领域的一项高新技术,代表了世界***钻井的发展方向。目前,水平井,大排水井,分支井等复杂井正在***蓬勃发展,并已大规模应用。传统钻井技术难以适应这些困难井的运行需求,地下打地热井联系方式,必须依靠***的引导技术。为了确保井眼轨迹的准确性。
钻井指南
几何方向:
通过井下测量工具(MWD/LWD)测量几何参数,并将井倾角,方位角和工具表面的值传输到控制系统,并且控制系统及时校正和控制井眼轨迹。






钻井工程术语

开发井:是指在油气田开发中钻探的各种石油生产井。注水注气井或调整井,在已开发的油气田钻探补充井,打地热井联系方式,保持一定的产量,研究开发过程中地下条件的变化。扩建井,检查数据井等
垂直井:井眼轴通常沿垂直方向及其井角。底孔的水平位移和全角的变化率都在有限的范围内。
定向井:沿预先设计的井眼轨道,在给定方向上与井口垂直于井口一定距离,到达目标井。
Cluster Wells:在井场或钻井平台上计划钻两个或多个定向井(可能包括垂直井)。

Well drilling c***truction technology and attention points
1. According to the requirements of the water output of the well,快速打地热井联系方式, the wellbore structure is designed with the well depth and the caliper,小型打地热井联系方式, 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.
