近期,由江苏油田分公司地质科学研究院提交的总公司重点探井C64井在目的层戴一段经压裂后喜获工业油流,目前抽深950 m,抽汲产液17.3 m3,产油5.0 m3(11月14日数据)。C64井是针对樊川次凹湖底扇岩性圈闭钻探的首口探井,该井试获工业油流不仅是高邮凹陷隐蔽油气藏勘探新类型的突破,同时也是高邮凹陷戴南组首口在垂深3 900 m以下通过压裂改造试获工业油流的 Recently, the key well exploration well C64 of the head office submitted by the Institute of Geology, Jiangsu Oilfield Branch, won the first section of fracturing in the destination zone and was awarded the industrial oil flow. The current depuration depth is 950 m, pumping production liquid 17.3 m3, oil production 5.0 m3 (November 14 data). The C64 well is the first exploratory well for the lithologic traps of the sub-fan fan in the sub-Sag of Fanchuan. The test of this well is not only a breakthrough in the exploration of subtle reservoirs in the Gaoyou sag but also the first in the Dainan Formation in the Gaoyou sag Down to 3 900 m below the depth of the pilot through the fracturing of industrial oil flow test
