【摘要】：石油天然气作为一种主要能源,已经成为世界性产业革命的支柱。随着对油气需求日益增长和勘探开发程度的不断提高,石油钻井所面临的地质环境越来越复杂。井眼轨道设计是一切钻井工程的基础,更是井眼轨道预测与控制的前提条件,所以本文开展井眼轨道设计的研究。本文结合前人的研究成果,阐述了井眼轨道设计的原则、轨迹的测斜计算和轨迹的控制等问题,然后以某井为例,结合该井的地质条件,采用“直—增—稳—增—增—增—增—稳—增—降—平”的十一段式设计轨道对该井进行轨道设计并得到了合理的结果。最后,为了解决钻井过程中的轨迹控制问题,又以该井为例详细的阐述了方位扭转角、造斜工具装置角和动力钻具反扭角的计算,从而使所研究的问题得到了解决。
[Abstract]:Oil and gas as a major energy, has become the pillar of the world industrial revolution. With the increasing demand for oil and gas and the increasing degree of exploration and development, the geological environment of oil drilling is becoming more and more complex. Borehole track design is the foundation of all drilling projects and is also the precondition of borehole track prediction and control. Based on the previous research results, this paper expounds the principles of borehole track design, trajectory deviation calculation and trajectory control, and then takes a well as an example, combining with the geological conditions of the well. The 11-section design track of "direct-augmentation-stability-augmentation-augmentation-augmentation-stability-level-leveling" is used to design the track of the well and the reasonable results are obtained. Finally, in order to solve the problem of trajectory control in drilling process, the calculation of azimuth torsion angle, angle of oblique tool and back torsion angle of power drilling tool are discussed in detail, so that the studied problem is solved.
