摘要
将非线性有限元的力学方法应用于水平井钻井摩阻的预测,在此基础上编制了一套大位移水平井摩阻计算软件,并于1997年底用软件为南海西部涠洲12-1平台的4口水平井作了钻井摩阻预测。以涠洲12-1-SI2井为例,给出了各种预测和实钻数据,通过讨论,得出了一些有价值的结论。
The paper discusseds the question of forecasting the drag and torque of string in drilling of horizontal wells by a method of nonlinear finite element. A set of saftware is developed according to such method. At the end of 1997,4 wells of NHWC were forecasted for drag and torque of drilling strings. This paper gives the forecasted data and measured data of well W 12-1-SPI 2 and some discussions.
