水平井钻井技术已经成为开发低压、低产、低渗油气藏的有效技术手段,而井眼轨迹控制技术是决定水平井施工成败的关键技术。在井眼轨迹控制过程中,直井段需要防斜打直,造斜段要保证顺利入靶,水平段施工要尽可能保证钻具稳平。本文对以上三个方面的关键技术进行了深入探讨,需要对现场井眼轨迹施工控制人员有一定的帮助。
Horizontal well drilling technology has become an effective technique for developing low pressure, low production and low permeability reservoirs, and well trajectory control technology is the key technology that determines the success or failure of horizontal well construction. In the process of well trajectory control, the straight section needs to be anti-inclined and straightened, and the inclined section should be ensured to ensure the smooth entry into the target. The horizontal section should be constructed to ensure the drilling tool to be as flat as possible. In this paper, the key technologies of the above three aspects are discussed in depth, and some help must be provided to the personnel in the field of well trajectory construction control.
