摘要

谐波地震采油技术是为开展适合稠油、低渗透油田高效开采的采收率技术研究而提出的一项物理法处理油层技术,是一项新的三次采油技术。分析了谐波地震采油技术提高原油采收率的原理、技术特点和油藏适用条件。从区块选择、方案设计、现场实施和效果评价等方面详细介绍了大港油田港西二区二断块谐波地震采油先导性矿场试验的情况,该断块谐波地震采油井段长850m,共振动94d,74口油井受益,采用自然递减法统计,3个月内累计增油4693t。现场试验表明,应用谐波地震采油技术可以提高原油采收率,且施工工艺简单,操作方便,投入少,产出高,对地层无伤害、无污染。
Oil recovery with harmonic seismic is a novel tertiary oil recovery technology for exploiting heavy oil or low permeable oil fields.The principles,mechanism and characteristics harmonic seismic and applicable reservoir condition were analyzed.The pilot test of this technology at the second fault block of the second section of Gangxi of Dagang Oilfield is introduced,including block selection,project design,field application and result evaluation.The well section length is 850m,and the vibration time is 94d.74 wells profit from the harmonic seismic,and total incremental oil production is 4693 tons within 3 months.Field tests show that the stimulation method is simple and has low cost and high output without formation damages and pollutions.
