Abstract

This paper presents the results of a engineering characteristic to the effect of drilling fluid with different mix designs for use in bore hole collapse prevention. The bore hole collapse prevention mechanism for the bentonite based drilling fluid was first discussed together with the effect of conditioning with different additives on engineering characteristics of bentonite based drilling fluid. As result, bentonite with polymer have a outstanding characteristics as compared to CMC Properties thickening effect In the case of sea water with attatulgite be superior to bentonite. Therefore, in this paper presented qualitative result on the performance of the drilling fluid depending on the water.

본 논문에서는 지반 시추 시 공벽붕괴 방지를 위해 사용되는 안정액의 다양한 배합비에 따른 공학적 특성에 대한 실험적 연구를 다루었다. 이를 위해 먼저 배합수가 청수일 경우, 안정액의 공학적 특성을 검토하였으며 아울러 해수 배합시 안정액의 공학적 성능 변화에 대한 공학적 특성을 분석하였다. 그 결과, 청수에서 벤토나이트와 폴리머를 추가할 경우 공학적 성능이 향상되는 것으로 나타났으며, CMC에 비해 Polymer의 증점 효과가 우수한 것으로 검토되다. 또한 해수의 경우 벤토나이트에 비해 내염성점토의 내염성 성능이 우수한 것으로 검토되었다. 따라서 본 논문에서는 시공시 배합수에 따른 안정액을 성능에 대한 정성적인 결과를 제시하였다.
