摘　　要：为了满足新木油田低孔隙度低渗透率高含水期老井剩余油挖潜的需求,采用迭代编程法实现地层混合液电阻率的连续求取,考虑泥质影响,优选新木油田低孔隙度低渗透率水淹层剩余油饱和度的计算方法,建立适合该油田高含水期水淹层测井精细解释方法,实现水淹层定性解释到定量准确评价。在单井精细解释的基础上,利用测井与地质油藏开发一体化老井潜力层评价技术研究了油田剩余油分布规律,系统评价了老井潜力,最终提出183口井的挖潜建议。目前采油厂挖潜126口井,累计增油2.06×105 t,有效解决了油田的生产难题,为各油田调整及老井措施提供了有力技术支持。In order to meet the need of tapping the potential of remaining oil in old wells of Xinmu oilfield with low porosity and low permeability in high water cut period.The iterative programming method is used to realize the continuous calculation of resistivity of formation mixed fluid,optimized the calculation method of remaining oil saturation in water flooded layers of Xinmu oilfield with low porosity and low permeability considering the influence of shale,established a fine logging interpretation method suitable for water flooded layers in high water cut period of the oilfield,and realized qualitative interpretation to quantitative and accurate evaluation of water flooded layers.On the fine basis of single well,the remaining oil distribution law of the oilfield is studied by using the evaluation technology of old well potential layer integrated with logging and geological reservoir development,and the potential of old wells is systematically evaluated.Finally,suggestions for tapping the potential of 183 wells are put forward.At present,the oil production plant has taken suggestions to tap the potential of 126 wells,with a cumulative increase of 2.06×105 tons of oil,effectively solving the oilfield production problems,and providing strong technical support for the adjustment and old well measures of each oilfield.
