本文介绍用解析法设计定向井剖面。根据已知条件,先用公式计算出最大井斜角,然后进行井身计算。为了设计和绘图方便,编制了定向井剖面设计和绘图的计算机程序。该程序适用于各种类型的定向井剖面,可直接用于PC-1500计算机,也可通过CE-158接口加接X-Y绘图机绘出多种尺寸的设计井身剖面图。该程序若作个别句法修改,也可应用在其它型号的微机上。基本公式直-增-稳-降-稳最大井斜角α_m的计算公式: (?) 式中:R_0=R_1+R_2 A_0=A-Axz+R_2(1-cosα_n) H_0=H-Hxz+R_2sinα_n_Hz 如果增斜段的造斜率有m(m>1)种;降斜段的降斜率有n(n>1)种,则式中的R_0、A_0、
This article describes the use of analytical methods to design directional well profiles. According to the known conditions, first calculate the maximum deviation angle formula, and then calculate the borehole. For the convenience of design and drawing, a computer program of directional well profile design and drawing was developed. The program is suitable for all types of directional well profiles and can be used directly in PC-1500 computers. It can also be used to create well-designed cross-section profiles of various sizes via the CE-158 interface plus an X-Y plotter. The program for individual syntax modification, can also be applied to other types of computer. The basic formula straight-increase-steady-down-steady-maximal well inclination angle α_m is calculated as follows: () where: R_0 = R_1 + R_2 A_0 = A-Axz + R_2 (1- cosα_n) H_0 = H-Hxz + R_2sinα_n_Hz If there are m (m> 1) kinds of slopes in the increase section, and n (n> 1) slopes of the descending section, R_0, A_0,
