      大慶油田取芯技術中心成立于1980年,其前身是大慶會戰鑽探指揮部鑽井技術研究所,1995年大慶油田帶資分流,改制成現在的股份制企業。是大慶油田所屬企業,且在國際首先實現取芯工具整體防腐磷化處理工藝,我中心集取芯工具、設計、制造、技術服務為一體的專業化廠家,現有高級工程師4名,工程師6名,技工25人。我中心産品在大慶油田應用40年,先後開發出“深井防倒扣常規取芯工具”、“密閉取芯工具”、“液壓密閉取芯工具”、“淺層液壓常規取芯工具”、“水平井取芯工具”、“斜井取芯工具”、“小直徑取芯工具(φ121取芯工具、φ127取芯工具、φ133取芯工具、φ140取芯工具、φ168取芯工具)”,從1998年“葡深—Ⅰ井”(4500m)到徐家圍子氣田彙戰,深度超過4000米,取芯井達87口,收獲率達99.8%,密閉取芯近150口,取芯收獲率達95%,密閉率達98%。井深從500m-5500m。青海冷湖石膏岩取芯收獲率達56%。天然金剛石孕鑲鑽頭在雄安新區地熱井3500m(含石英花崗岩)取芯進尺速度每小時0.5m進尺,收獲率100%的好成績。河北地礦第四水文工程地質大隊3000m兩口全井取芯,彈性膠質泥岩取芯收獲率達80%。長慶油田下寺灣3300m礫石性破碎硬地層取芯收獲率達85%,密閉率達90%。我單位先後為國内各大油田,各大鑽井公司提供近百次服務,受到五普、四川、大港、吉林、新疆、長慶、山東勝利、天津地熱勘察開發設計院、河北地礦、山東地礦、内蒙古煤田、山西煤田、山東科瑞、香港中科百田、北京華油以及國外十幾個國家的好評。産品出口俄羅斯,哈薩克,烏克蘭,美國,蘇丹,哥倫比亞等十五個國家。獲得專利8項,是中國兩大取芯專業公司之一(在中國隻有四川管理局川慶取芯與我們大慶油田取芯是兩隻專業隊伍)。

      Daqing Oilfield Coring Technology Center was established in 1980. Its predecessor was the Drilling Technology Research Institute of Daqing World War Drilling Command. In 1995, Daqing Oilfield was diverted with capital and transformed into a joint-stock enterprise. Daqing Oilfield affiliated enterprises, and in the international first to achieve coring tools overall anti-corrosion phosphating treatment process, our center set coring tools, design, manufacturing, technical services as one of the professional manufacturers, the existing senior engineers 4, engineers 6, technicians 25. Our center products have been applied in Daqing Oilfield for 40 years, and have developed "deep well anti-inversion conventional coring tools", "closed coring tools", "hydraulic sealing coring tools", "shallow hydraulic conventional coring tools", "horizontal well coring tools", "inclined well coring tools", "small diameter coring tools" (121 coring tools, 127 coring tools, 133 coring tools, 140 coring tools). Coring tools and 168 coring tools". From Pushen-I well (4500m) to Xujiaweizi gas field in 1998, the depth exceeded 4000 meters, with 87 coring wells reaching 99.8%, nearly 150 sealed coring wells reaching 95% and 98%. The well depth ranges from 500m to 5500m. The core recovery rate of Qinghai Lenghu gypsum rock is 56%. The natural diamond impregnated bit has achieved good results in taking core footage of 3500m (quartz-bearing granite) in geothermal wells of Xiongan New Area at a speed of 0.5m footage per hour with a yield of 100%. The core recovery rate of elastic colloid mudstone is 80% in two wells of 3000m in the fourth hydro-engineering Geological Brigade of Hebei Geological Mine. Coring recovery and sealing rate of 3300m gravelly fractured hard formation in Xiasiwan, Changqing Oilfield coring recovery rate is 85% and Core sealing rate is 90%. Our unit has provided early a hundred services for major oil fields and drilling companies in China. It has received high praise from Wupu, Sichuan, Dagang, Jilin, Xinjiang, Changqing, Shandong Shengli, Tianjin Geothermal Exploration and Design Institute, Hebei Geological Mine, Shandong Geological Mine, Inner Mongolia Coalfield, Shanxi Coalfield, Shandong Kerui, Hong Kong Zhongke Baitian, Beijing Huayou and more than a dozen foreign countries. Products are exported to Russia, Kazakhstan, Ukraine, the United States, Sudan, Colombia and other 15 countries. Eight patents have been granted, which is one of the two major coring companies in China (only Chuanqing Coring Company of Sichuan Administration and our Daqing Oilfield Coring Company are two professional teams in China).
