【摘要】：本课题着重针对大位移钻井施工的摩阻、扭矩与套管磨损预测技术进行研究。它是为解决在南堡滩海大位移井常规钻井开发过程中遇到的钻井周期长、井下复杂、事故多等问题而题展开的一系列配套的技术研究重要组成部分。本文对摩阻计算模型、钻井液粘滞力模型、钻井液粘性扭矩计算、管柱屈曲模型、大钩载荷校正、钻井液浮力影响、减阻工具的影响与安放优化等问题进行了讨论。针对上述问题建立了相应的计算模型,并将这些模型应用于软件中。通过冀东油田NP23-P2013井的钻前摩阻扭矩预测结果制定了相应的减扭方案。此后,通过对该井的实钻时数据采集、对比验证了模型的准确性。本文还通过使用有效的磨损预测技术对NP23-平2001井进行了套管预测,计算出了满足被磨损套管抗内压要求的机械钻速。实验证明,该项目的研究能够为南堡油田的高效开发和现场施工提供可靠、有效的技术支持,同时也能为类似油田的开发提供适用配套技术,以提高其综合效益。
[Abstract]:This topic focuses on the study of the friction, torque and casing wear prediction technology in large displacement drilling, which is an important part of the technical research for solving the problems of long drilling cycle, complicated underground and many accidents in the routine drilling process of the large displacement well in Nanpu beach. The problem of resistance calculation model, viscous force model of drilling fluid, viscous torque calculation of drilling fluid, pipe column buckling model, hook load correction, drilling fluid buoyancy influence, effect of drag reduction tool and placement optimization are discussed. The corresponding calculation model is established for the above problems, and these models are applied to the software of Jidong Oilfield NP23- The prediction results of the friction and torque of the P2013 well have worked out the corresponding reduction scheme. After that, the accuracy of the model is verified by the data collection of the real drilling time of the well. By using the effective wear prediction technique, the casing prediction is carried out for the well NP23- 2001 well, and the machinery to meet the internal pressure requirements of the worn casing is calculated. The experiment proves that the research of this project can provide reliable and effective technical support for the efficient development and site construction of Nanpu oil field, and can also provide suitable supporting technology for the development of similar oil fields, so as to improve its comprehensive benefit.
