A “Table of Drilling Weights to be Chosen...

Based on the concept that the deflection resistance of drilling tools equals the deflecting force of strata when the side resultant acting on the bit equals zero and from analysis of data of drilling 95 wells in the cooked-hole part of the field, a deflection factor of strata for different formations under different deflection angles is worked out and an optimum drilling weight is calculated for drilling vertical holes in different sections with varying deflection angles. A “Table of Drilling Weights to be Chosen for Wangchang” is worked out which proves to be applicable from test on 5 holes.

本文根据作用在钻头上的侧向合力为零时,钻具的防斜力等于地层的造斜力这一基本概念,通过易斜区95口井的实际钻井资料的分析和数学计算,求出不同地层、不同倾角下的地层造斜系数,计算出各个层段不同井斜角下适应于钻垂直井的最佳钻压。同时还制作了一套《王场地区选定钻压表》。经5口井试验,按选定钻压方法计算的钻压,井斜数据与实际情况相吻合。

The choice of optimal parameters for design of pendulum bottomhole asse- mbly with double stabilizers used in vertical hole with very small deflection angle is discussed, based on the continuous beam theory. A design of flexible ass- embly with double stabilizers(i. e. , with a flexible drilling stem between the two stabilizers) is achieved which has the greatest side force that increases with drilling load for deflection prevention. Another design of rigid assembly with do- uble stabilizers(i. e. , with a rigid...

A design of flexible ass- embly with double stabilizers(i. e. , with a flexible drilling stem between the two stabilizers) is achieved which has the greatest side force that increases with drilling load for deflection prevention. Another design of rigid assembly with do- uble stabilizers(i. e. , with a rigid drilling stem between the two stabilizers) is also sought. The new design gives a side force 40~60% higher that of the conve- ntional.

为了提高钟摆钻具的防斜侧向力,本文应用纵横弯曲连续梁理论,研究在井斜角很小的垂直井中,对双扶正器的钟摆钻具组合如何使用优化方法合理选择钻具参数。采用“对分法”和“伸缩保差法”作为搜索方法,得出防斜侧向力最大的并随着钻压增加而增大的“双扶正器柔性钻具组合”(即两扶正器之间为柔性钻杆)。又对“双扶正器刚性钻具组合”(即两扶正器之间用刚度较大的钻铤)进行优化设计,从而取得了对不同造斜地层打钻时进行参数优选的规律性。优化设计后具有双扶正器的柔性和刚性钟摆钻具可较光钻铤钻具的防斜侧向力有显著的提高(可提高40~60%)。

Treating the basic equation of Mukherjee-Brill dipping tube two-phase flow as a primary value problem of ordinary differential equation, this paper carries out numerical solution by use of RungeKutta method. This is a simple and direct and more usual new trial-and-error method, avoided to adopt average parameters. The flow pattern, flow direction and slope of tube have been considered in the formula used for calculating the holding liquid rate and friction coefficient of the two-phase flow and it is applicable to pressure calculation of two-phase flow in directional wells(also vertical wells).
