摘　　要：以F、S油田为例,建立高含水井(层)的数值模型,分析高含水井(层)模拟压裂效果,从细分沉积相研究入手,综合动态分析、数值模拟和经济评价等技术,寻找高含水层内有利挖潜对象和可压裂层位,解决了外围低渗透油田开采后期高含水井(层)的压裂挖潜问题。经过近一年的现场试验,所选井(层)的初期日增油达2.9 t,充分发挥了高含水井(层)的生产潜力,为外围低渗透油田开发后期,提高高含水井(层)单井产量的措施挖潜,提供了经验和依据。Taking F2S Oilfield as an example,build high containing water Wells(layers)of number value model,analyse the high containing water Wells(layer)die quasi compression crack effect,from the perspective of the subdivision of sedimentary facies research,comprehensive and dynamic analysis,numerical simulation and economic evaluation technology,such as searching for favorable exploration objects and in the high aquifer can fracturing horizon,solved the peripheral low permeability oilfield exploitation period of high water Wells(layers)of fracturing potential problems.After nearly one year of field test,the selected Wells(beds)have an initial daily oil increase of 2.9 t,which gives full play to the production potential of high waterbearing Wells(beds)and provides experience and basis for the measures to improve the single well production of high water-bearing Wells(beds)in the late development of peripheral low permeability oil fields.
