【摘要】：石油天然氣作為一種主要能源,已經(jīng)成為世界性產(chǎn)業(yè)革命的支柱。隨著對油氣需求日益增長和勘探開發(fā)程度的不斷提高,石油鉆井所面臨的地質(zhì)環(huán)境越來越復雜。井眼軌道設計是一切鉆井工程的基礎,更是井眼軌道預測與控制的前提條件,所以本文開展井眼軌道設計的研究。本文結(jié)合前人的研究成果,闡述了井眼軌道設計的原則、軌跡的測斜計算和軌跡的控制等問題,然后以某井為例,結(jié)合該井的地質(zhì)條件,采用“直—增—穩(wěn)—增—增—增—增—穩(wěn)—增—降—平”的十一段式設計軌道對該井進行軌道設計并得到了合理的結(jié)果。最后,為了解決鉆井過程中的軌跡控制問題,又以該井為例詳細的闡述了方位扭轉(zhuǎn)角、造斜工具裝置角和動力鉆具反扭角的計算,從而使所研究的問題得到了解決。
[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.
