6月26日,辽河油田生产日报显示,油田勘探开发研究院稠油所在洼60-H25井组实施重力泄水辅助蒸汽驱先导试验后,日产油达到67.9吨,比单纯采用蒸汽驱提高了44%。重力泄水辅助蒸汽驱技术日前申请国家专利4项,2项获得授权。洼60-H25井组是辽河冷家油田洼59块典型的超稠油油藏。经过10年吞吐开发,区块周期产量及油汽比不断降低。为了保证区块长期稳产,2009年,辽
On June 26, daily production of Liaohe Oilfield showed that daily output of crude oil reached 67.9 tons after implementing the gravity drainage auxiliary steam flooding pilot test in the depression of Well 60-H25 in the Oilfield Exploration and Development Research Institute, which was 44% more than that of steam flooding alone %. Gravity drainage auxiliary steam flooding technology recently applied for 4 national patents, 2 were authorized. Well 60-H25 is a typical ultra-heavy oil reservoir in depression 59 of Lengjia Oilfield, Liaohe River. After 10 years of development and development, the block cycle output and the ratio of oil to gas are continuously decreasing. In order to ensure a long-term stable production area, in 2009, Liaoning
