초록
회전식 방향제어 시스템(rotary steerable system, RSS)은 기존 회전식 시추에서 적용되는 슬라이드를 수행하지 않고 시추공의 방향을 제어할 수 있는 기술이다. 따라서 연속적인 시추를 통해 시추작업에 소요되는 시간을 단축할수 있으며, 고착현상(stuck) 발생 가능성을 낮출 수 있다. 그러나 공저장비의 거동 및 편향을 예측하기 위한 많은노력에도 불구하고 시추궤도에 대한 RSS의 각 설계요소의 영향이 규명되지 않은 실정이다. 이에 본 연구에서는 RSS의설계요소와 시추궤도의 관계를 도출하기 위한 콘크리트를 이용한 지오블록(geoblock) 실험장치를 설계하였으며, 각설계요소 값의 시험기준에 대한 지침을 수립하였다. 향후 본 연구의 결과는 RSS의 성능평가 및 각 설계요소의 최적화에 효과적으로 이용될 수 있을 것으로 판단된다.
Abstract
Rotary steerable system(RSS) allows continuous rotation of the drill string while steering the bit, eliminating the need to slide a steerable motor. It reduces drilling time and stuck pipe significantly. However, rotary steerable system shows poor reliability to steer the bit to the target reservoir in spite of many studies conducted on predicting the tendency of BHA. This study presents the design of experimental concrete geoblock and guidelines for criteria to understand the relationship between design parameters and trajectory. It can be utilized to evaluate the performance of rotary steerable systems and optimize its design parameters.
