摘　　要：七里村油田主要开发层系为长6油层,储层埋藏浅,为多产层特低渗、低压、低产油藏。储层孔隙度平均8.71%,渗透率平均0.54×10^(-3)μm^2,平均采收率为7.9%。根据试验区注水开发现状,开展生物酶驱油试验,对试验效果进行了分析评价,为同类低渗透油藏注水开发提供了宝贵经验。The major layer series of development in Qilicun oilfield is Chang 6 oil reservoir set,the reservoir is shallow burial depth, multipay and special low permeability,low-pressure,low yield, with average porosity of 8.71 %,the average permeability rate of 0.54 ×10-3μm2.According to water flooding current status of exploitation in experimental area,test of enzyme oil displacement as carried out,analyze and evaluate the test results, providing valuable experiences for homogeneous water flooding in low permeable oilfields.
