국내에서 처음으로 지구물리검층 보정을 위한 모형시추공이 건설되었으며 이들 모형시추공을 이용한 검출기 보정실험과 케이싱보정을 위한 기초실험을 실시하였다. 여기서는 세 가지 밀도와 세 가지공경으로 구성되는 모형 시추공의 건설 과정과 재원을 소개하고 이를 이용하여 구해진 선형 관계의 밀도-검출기 반응식을 검토하였다. 아울러 케이싱 보정을 위한 기초연구 결과 이격 보정용 차트가 제시되었고 이를 이용하여 이격 정도를 모르는 현장 측정에서도 참 밀도를 구할 수 있음을 밝혔다.

We constructed a series of calibration models in the campus of Kangwon National University. A series of experiment for calibrating sonde response as well as casing effect in field measurement. Here we explained the process of construction of calibrating facility which consists of three model holes of different density and three model holes of different diameter. It was discussed the calibration equations obtained from its sonde response calibration test. A density correction chart for different separation of detector from hole wall was suggested, and verified the possibility of determining true density from measurements in cased hole.
