돌고래-1 공 석유근원암의 화학분석 = Chemical Analysis of the Dolgorae-1 well Petroleum Source Rock

국문 초록 (Abstract)

한국 대륙붕 블럭 VI의 돌고래-1공에서 채취한 근원암의 화학성분 및 특성에 관해 조사하였다. 유징분석기를 사용하여 가스, 기름 및 총추출유기물의 양을 구했으며 총추출 유기물의 양은 0.59%이었다. 비투멘의 양과 분자량은 용매추출법과 겔투과 크로마토그라피에 의해 구했으며, X-선회절법, 적외선분광법 및 열무게 측정법으로 물리화학적 성질을 고찰하였다. 분석 결과로부터 돌고래-1공의 시료는 미미한 석유근원암으로 평가 되었다.

The chemical composition and characteristics of the source rock collected from Dolgorae-1 well in Korea continental shelf block VI(35。 18`N.L.,130。 28`E) have been investigated. An oil show analyzer(OSA) has been used to determine the contents of gas, oil and total organic carbon(TOC). The average TOC value for the sample is found to be 0.59%. The OSA has also provided hydrogen index and T_(max), the maximum temperature which generate maximum hydrocarbons from kerogen. From a T_(max)-hydrogen index diagram the type of organic matter in the source rock was estimated to be type III kerogen. The content of bitumen and its molecular weight have been determined by means of extraction method and gel permeation chromatograph, respectively. The physicochemical properties has been studied using X-ray diffraction spectrometer, IR spectrometer and thermogravimetric method. On the basis of the results obtained in the present work, the samples collected from Dolgorae-1 well are evaluated to be poor source rocks.
