The Research Of Fracture Technology For Naiman Oilfield

Both permeability of reservoirs and natural productivity of oil wells are low in Naiman Oilfield of Liao Xing Oil &Gas Development Company.Average permeability is11.4×10^-3μm².Average single well produces 0.72 t every day by natural energy exploitation.Therefore,single well’s production is improved by reservoir compression fracture transformation.According to the reservoir’s characteristics and development status of Naiman Oilfield,focising on “three low” reservoir characteristics,aiming to improving single well’s production and solving the fracturing problems of the block,we actively carry out fracturing technology research and site test application by the means of optimizing the design of fracture and the tracking effect of fracture,forming the fracturing technology system suitable for the reservoir characteristics of the block,which contains optimization technology of fracturing design parameters,fracturing fluid formulation and the proppant.Otherwise,site liquor and quality control technology,technology of improving the flowback rate and compound plugging technology for fractured wells are included.Continuous improvement of the fracturing technology system and implementation level of Naiman Oilfield provides the technical guarantee of the economic development of the block.Integrated applications of a number of technologies form the fracturing matching technology for Naiman Oilfield.
