基于提高下尾管悬重预测精度的方法与应用
|
摘要
渤海油田渤中34-2/4区块地质复杂,一直存在井壁失稳、缩径和井漏等问题。为了减少复杂情况,提高下尾管作业效率,对下尾管悬重预测显得尤为重要。常规预测下尾管悬重的方法存在着摩擦系数取值可靠性低,下尾管悬重预测精度较低。本文对下尾管悬重预测方法进行了研究,从区块摩擦系数库的角度入手,探索出了一种新方法,该方法能提高下尾管悬重预测精度,提高了软件的使用效果,对现场指导作用更强,具有借鉴意义。
The geological condition of Bozhong 34-2/4 block of Bohai oilfield is very complex, it has problems such as wellbore instability, well hole shrinkage and lost circulation. In order to reduce complicated conditions and improve the operation efficiency of running in liner, it is very important to predict the weight of running in liner. The conventional method for predicting the weight of running in liner has low reliability of frication factor value and low prediction accuracy of the weight of running in liner. In this paper, the method of predicting the weight of running in liner is studied. From the perspective of the block friction factor library, a new method is produced. This method can improve the prediction accuracy of the weight of running in liner, and improve the use effect of the software. It has a stronger role in on-site guidance and can be a reference.
