采用精细地质研究、油藏综合动态分析、数值模拟和经济评价等技术，解决宋芳屯油田葡萄花油层高含水油井的压裂挖潜问题． 结果表明：高含水油井存在相当数量有待解放产能的非主力层． 当全井含水为４０ ％ ～８０ ％ 时，非主力层处于注水受效旺盛期，适宜压裂． 压裂层选取标准为厚度大于１ ．５ ｍ 、地层压力大于８ ．０ Ｍ Ｐａ 、有效渗透率为２０ ×１０ － ３～６０ ×１０ － ３ μｍ ２ 、水淹层（ 或高含水层） 与压裂层（ 未水淹） 有效渗透率比值为１ ．５ ～５ ．０ ． 高含水油井采用压裂技术开发后，４ 口压裂井平均单井日增油２ ．９ ｔｄ ，预计全年增油量可达３ ０８４ ｔ ．
Using fine geology research, integrated reservoir dynamic analysis, numerical simulation and economic evaluation techniques, the fracturing and tapping potential of the Putaohua oil-bearing high water cut oil well in Songfangtun Oilfield is solved. The results show that there exists a considerable amount of non-main layers to be released for production in high-water-cut oil wells. When the whole well water content is 40% -80%, the non-main layer is in a period of strong water injection and is suitable for fracturing. Fracturing layer selection criteria for the thickness greater than 1. 5 m, formation pressure greater than 8. 0 M Pa, and the effective permeability is 20 × 10 -3 ~ 60 × 10 -3 μm 2. The effective permeability ratio of water flooded layer (or high aquifer) to fractured layer (not flooded) is 1. 5 ~ 5. 0. After the development of fracturing technology for high water cut oil wells, the average pressure of 4 fracturing wells increased by 2%. 9 td. It is estimated that the annual oil increase will reach 3 084 t.
