Summary:Recently, shale gas has become an important energy source. Directional drilling is an imperative technology when it comes to excavating shale gas because it exists in underground in horizontally spaced areas. A rotary steerable system (RSS) enables the effective directional drilling. In general, there are two types of RSS, the point-the-bit and the push-the-bit. In this paper, a new hybrid type RSS is proposed. The hybrid type RSS has advantages of both the point-the-bit and the push-the-bit. We expect that the proposed RSS can increase the build-rate. The effectiveness of the proposed mechanism is discussed by predicting the side force.
