Abstract
Aiming at the currently high watered-out problem of Xingshugang Oilfield in Daqing Oilfield, one kind of compound enduring-effect foam system has been developed. The half-life period of this system is 54 hours, the foaming volume is above 475 ml, and it is suitable for the reservoirs with the temperature below 50℃ and the salinity less than 10g/L. The result of homogeneous core experiments shows that the recovery factor can be increased by 17% by injecting foam slug after waterflooding. The field test of Well Xing 7-1-33 shows that the response of the connected oil producers has changed after treatment with obvious increase of oil production rate and decrease of water cut. The cumulative incremental oil production rate from the well group has reached 3186 t with the input/output ratio of 1: 3. 68. This foam system can effectively prevent the injected water from advancing suddenly along the high permeability part and improve the displacement efficiency as well; therefore it can satisfy the demands of waterflooding development of high-permeability reservoirs in Xingshugang Oilfield.关键词
