近十年来,随着海洋石油的开发,定向钻井技术得到很大的发展。定向钻井就是沿着予先设计的井眼轨迹钻达目的点的钻井技术。这种钻井方法可使一个海上平台完成十几口油井,从而大大节省时间和费用。定向钻井,必须要有一种在钻井过程中随时可以测得井身走向参数的设备。本文介绍一种把航天技术应用于石油钻井的随钻测斜定向系统。测斜定向系统运用惯导器件及技术,实 Over the past decade, with the development of offshore oil, directional drilling technology has been greatly developed. Directional drilling is the drilling technique that reaches the destination along pre-designed borehole trajectories. This method of drilling allows a dozen offshore wells to be completed, saving significant time and money. Directional drilling, there must be a ready to measure well direction parameters during drilling. This article presents a measurement-while-drilling directional-orientation system that applies space technology to oil drilling. Inclinometer directional system using inertial navigation devices and technology, real
