摘要：旋转乎向和马达导向是定向站并中2种主要导向钻并方式，能够满足大部分常规定向并和水平并的导向钻并需求获转乎向价格高、效率高，马达导向成本低、效率低，在方案设计、项目管理过程中，经常会遇到导向方式选择的难题。结合动海油图实践经验，用特定区块的马达平均日进尺和旋转导向平均日进尺比值作为马达效率表征值E，结合钻并综合日费，计算出2 种导向方式费用相同时的效率表征值平衡点E，通过比较E与E，大小优选出经济性好的导向钻并方式，并绘制了快捷方使便的应用查询图版。通过SZ36-1油田20多口并的实站数据，应用该方法进行了快建经济评价，证明了该方法的科学性和实用性，提高了项目管理决策效率，节约了钻并成本，为石油工程中其他提建提效工具、仪器的优选提供了较好的借鉴意义。

Abstract: Rotary steering and steering motor are two main steering drilling modes for directional well drilling, and they can meet the steering drilling requirements of most conventional directional wells and horizontal wells. Rotary steering is of high cost and effi-ciency and steering motor is of low cost and efficiency, so it is often difficult to determine which steering mode to select in the process of program selection and project management. In this paper, the practical experience of Bohai Oilfield was taken as the example. The ratio of average daily footage of steering motor to that of rotary steering in a particular block was taken as the motor efficiency characteriza-tion valuc (E), and then combined with the daily composite drilling cost, the equilibrium point (E,) of efficiency characterization value at which the cost of rotary steering was equal to that of steering motor was calculated. Afterwards, the steering drilling mode which was cconomically better was selected by comparing E with E., and the quick and convenient application inquiry chart was plotted. Finally this method was applied to carry out quick economic evaluation on the actual drilling data of over 20 wells in SZ 36-1 Oilfield. It is proved that this method is scientific and practical, and it increases the decision making efficiency of project management and saves the drlling cost. It can be used as the reference for the selection of other speed and eficiency improvement tools and instruments in the field of petroleum engineering

目前，导向钻井方式主要有旋转导向钻井和马达导向钻井两种，且二者使用范围有很大重合区域【1]。
与传统的马达导向相比旋转导向销并技术在钻并过程中，井下工具一直处于旋转状态，有利于井眼的
