【摘要】：钻井生产中的井下钻具振动问题是钻井方面的难题。同时为了增加储层的开采效果定向井生产比例在油气开发中呈上升趋势,这就难免要提到钻具振动对无线随钻仪器使用的影响。其实这些复杂的井下振动正是造成无线随钻仪器故障和损坏的主要原因之一。油田的实践和近年来对井下事故的研究表明,测量并控制井下振动将能很好地提高钻速并对保护钻具和仪器设备有重要作用,在当今大量对钻井振动的深入研究中已经了解到这种复杂运动所引起的冲击含有巨大的能量,能够最大程度地破坏井眼中的电子设备,剧烈的纵向、扭转、横向、耦合力能够造成无线随钻仪器故障。通过分析钻具振动特性以及结合生产实际中振动对无线随钻仪器的危害实例,总结数据并在今后的钻井生产中制取相应的措施,可提高无线随钻仪器使用的稳定性,避免因无线随钻仪器故障而造成的起下钻作业,可提高钻井效率,降低生产开发成本,节省钻井周期,具有较大的社会经济效益前景。本文从数学理论结合钻井生产建模,论证计算的数据具有很强的科学价值,再对井下多重振动分解后逐个研究分析其产生原因和影响因素,对比实际使用无线随钻仪器时遇到的振动干扰、测量误差、数据失真和仪器本体损坏等现象,直观的表现了理论和实际的联系。
[Abstract]:The vibration of downhole drilling tools in drilling production is a difficult problem in drilling, and in order to increase the production ratio of directional wells in oil and gas development, the production ratio of directional wells is on the rise in oil and gas development. It is inevitable to mention the influence of drilling tool vibration on the use of wireless drilling instruments. In fact, these complex downhole vibration is one of the main reasons for the failure and damage of wireless drilling instruments. The practice of oil fields and the downhole in recent years. Studies of accidents show that. Measuring and controlling downhole vibration will improve drilling speed and play an important role in protecting drilling tools and instruments. To the maximum extent of damage to the hole's electronic equipment, violent longitudinal, torsional, horizontal, The coupling force can cause the fault of the wireless drilling instrument. By analyzing the vibration characteristics of the drill tool and the harmful example of the vibration in the production practice, the data are summarized and the corresponding measures are taken in the drilling production in the future. It can improve the stability of the wireless while drilling instrument, avoid the drilling operation caused by the failure of the wireless drilling instrument, improve the drilling efficiency, reduce the production and development cost, and save the drilling cycle. It has a great prospect of social and economic benefits. This paper demonstrates that the calculated data have strong scientific value from mathematical theory combined with drilling production modeling, and then analyzes the causes and influencing factors of underground multi-vibration decomposition one by one. Compared with the vibration interference, measurement error, data distortion and instrument body damage encountered in the practical use of wireless instruments while drilling, the paper intuitively shows the relationship between theory and practice.
