摘要
论述了子午线收敛角校正在定向井轨迹计算中的重要性,介绍了子午线收敛角的定义和性质,以及子午线收敛角的计算方法和在定向井井眼轨迹计算中进行子午线收敛角校正的方法。希望我国各油田尽快推行石油天然气行业标准SY/T543—2003规定的子午线收敛角校正。
The necessity and importance about grid correction in survey calculation of directional drilling are discussed, The concept of the meridian convergence angle is introduced. The methods to calculate the meridian convergence angle and the methods of grid correction are given. The purpose of the paper is to spread the rule of grid correction according to specification of SY/T5435-2003 in our country soon.
