目前在辽河油田勘探开发研究院的档案室里,有18个岩心库房,陈列着10万余米的钻探岩心,成为下辽河拗陷地下岩心标本的实物档案群体。从1964年起,国家地质部第二普查勘探大队在下辽河拗陷的黄金带地区钻探辽1取心井,到1993年底,在下辽河拗陷的石油勘探钻井中,共有2136口取心井,累计收获岩心100979.89m,平均取心收获率为88.6%。这些取心井中,在同一口井中取心最长的是锦82井,取心进尺320.74m,收获岩心长303.85m;取心最短的是杜51井,取心进尺0.3m,获取岩心0.25m。岩心档案利用率最高的是欢11井,科研人员观察研究该井岩心80余次。 10万米岩心按每一延长米(含不足一米)装入长
Currently in the archives of the Liaohe Oilfield Exploration and Development Research Institute, there are 18 core coffers displaying more than 10 million meters of drilling cores and becoming the physical archives of underground core samples in the Lower Liaohe River Depression. Since 1964, the Second Census Exploration Brigade of the State Department of Geology has been drilling Liao 1 coring wells in the gold belt area of the Lower Liaohe River Depression. By the end of 1993, there had been a total of 2136 coring wells in the oil exploration drilling in the Lower Liaohe River Depression. The core was harvested 100979.89m, the average coring yield was 88.6%. Among these coring wells, the longest coring in the same well is Jin-82 well, the coring footage is 320.74m, the harvesting core length is 303.85m; the shortest coring is Du-51 well, the coring footage is 0.3m, the core is 0.25m . Core file utilization is the highest Huan 11 Well, researchers observed the core of the well more than 80 times. 100000 meters of core by each extension of rice (less than one meter) into the long
