| Abstract: | The carbonate reservoir has some features in Tahe oilfield,such as deep buried depth,high formation temperture,low pemeability and strong heterogeneity.According to different reservoir type,applying acid fracturing techniques of gelled acid and emulsification acid system improve the fracture conductivity.It has 95percent of the contruction success ratio and 60 percent of the well efficiency.Increase productivity occupy 40 percent of the crude oil daily output and increasing the proved reserves is a hundred million tons.It is one of the main measures for Tahe oilfield's exploration,stable production and increase productivity. |
