Study Of Fracturing Process Technique In Yushulin Oilfield

As it is used widely in exploration and development in the low permeability oin-gas reservoirs, and a great deal of economical benefit were achieved, the technique of hydraulic fracturing has been developed on theoretical method, process design, equipment and appliance and so on. The science and reasonable development in the low permeability reservoir is very important and urgent. With the development of new technology in the oil filed, all kinds of corresponding theories and technologies are carrying out deeply.Hydraulic fracturing plays an important role in creasing production of with low peameability reservior and it also is the prime approach to raising the rat of oil-gas extraction. As a result, it is vital to make reseach on hydraulic fracturing.On the basis of geologic study of pre-fracturing and fracturing optimization in yushulin oilfield, an overall study is performed on large scale fracturing technique in the oilfiled from the aspects of optimizing the design parameters, optimizing the fracturing fluid system, determing the fracturing scale and optimizing the proppants. The result of application shows that the altitude of the production improve is high, pay back of investment is fast and economic benefit is fast and economic benefit is obvious of the fracturing technique.
