Low permeability reservoir bed has a large seepage resistance force to the flow of fluids in it, and reservoir bed fluids can flow only when a pressure is above certain pressure which is called startup pressure,which acts on it, so waterflooding development of low permeability reservoir is hard. There is a big difference on the ratio of harvesting among layers because of large differences on seepage ability among layers and on the plane of a heterogeneity reservoir. Uncommenly high pressure reservoir in Bohai Gulf Basin is generally lack pressure type. The pressure of reservoir descends after it is putted into developing which results the descents of permeability and porosity,and the descents of permeability and porosity cannot be completely recovered, thus causes an affect the effects of development. The temperature and pressure of deep reservoir are high, so its development needs high technics and technology. Wen 33 block, a low permeability reservoir was developed with a high efficiency by the development method of combination zone by zone upgoing, subdivided series and adopting a whole set of technology focused on integer fracturing.
