摘　　要：针对文东高压低渗油藏注水开发中层间矛盾突出,水驱动用程度差异大、构造复杂,局部区域注采井网不完善、井况损坏严重,储量控制程度不断降低、二三类储层动用程度低的问题,采用油藏工程方法与数值模拟技术相结合对剩余油分布进行精细刻画,明确了剩余油的分布特征。研究结果表明文东高压低渗油藏剩余油潜力较大,剩余油主要为断层遮挡、层间干扰、注采不完善三种类型,但不同区块剩余油类型有所不同。根据剩余油研究成果,在矿场实践过程中利用各种精细工艺配套技术,并结合精细注采管理,实施了各类注采调整挖潜措施,提高了文东高压低渗油藏水驱动用程度。According to the problems of serious interlayer contradiction during waterflooding of high pressure and low permeability reservoir in Wendong oilfield, big difference of producing degrees of water flooding, complex structures, imperfect well patterns in local area, and so on, the distribution of remaining oil was described by using both reservoir engineering method and numerical simulation, the characteristics of remaining oil distribution were determined. The results show that the high-pressure and low permeability reservoir in Wendong oilfield has large remaining oil potential, the type of remaining oil can be divided into fault screened type, interlayer plane interference type and injection-production imperfection type, but different blocks present different types. Based on the research result, using various fine matched technologies during the field practice, combined with fine injection and production management, the implementation of a variety of injection and production adjustment measures to tap the potential, the waterflood producing degree of high pressure and low permeability reservoirs in Wendong oilfield was improved.
