Abstract: The advanced techniques of modern steering drilling are developing fast and making a greet progress in recent years.China is facing the challenge and should increase the investment of research on these techniques in order to speed up the progress.The key techniques of the modern steering drilling include rotary steering drilling,the geometric steering and the geologic steering drilling techniques.The function of the geologic steering technique is emphasized.It is indicated that the slid-steering drilling and"rotary-motor combination drilling"will lead to quite a few malpractices.Rotary steering drilling is the direction for developing the modern steering drilling.The main reasons for that are based on several facts as follows:①Its friction force and torques are lower;②The penetration rate is higher;③The bit footage is longer;④The drilling efficiency is higher;⑤The well construction period is shorter;⑥The well trajectory is smother;⑦The critical limited drilling depth can reach 15000 meters;⑧The footage cost per meter is lower.The principles and the controlling theory of the rotary steering drilling,the five subsystems of the rotary steering drilling system,the working principle and kind of construction, the present progress and the developing trend of the rotary steering drilling tool are discussed.The author points out the developing direction of modern steering drilling technique and gives several advices to increase the speed of the drilling industry’s development in China.
