| Hydraulic fracturing technology is a very key technica,it can improve oil and gas well production and injection Wells in recent yearsl measures of injection,also is the key to improve reservoir recovery factor,at the same time also played a positive role for the development formation.This paper analyzes the present situation of hydraulic fracturing technology at home and abroad and prospects,especially comparing the development of hydraulic fracturing in 1990 began to design optimization and developed around 2000 new materials associated with hydraulic fracturing technology,such as proppant,fracturing fluid,additives,and analyzes the domestic development trend of hydraulic fracturing technology.According to a new technology in recent years in water fracturing,the paper analyzes the technical characteristics of water fracturing,fracturing and affecting water dimensionless flow conductivity parameters including permeability,closure stress,young’s modulus and so on,they and the dimensionless flow conductivity how relationship exists between the size of the how to change the parameter through the experiment in order to improve the flow conductivity.On this basis,this paper focuses on the water without sand fracture diverting capacity and production of formation,analysis of fracture length,fracture width,surface roughness of rock and other related parameters on the water without the influence of sand fracturing,and at the same time in terms of north oilfield in fuyu reservoir by establishing the productivity prediction model,to predict the capacity compared with the actual production,analysis the formation without sand fracturing technology suitable for water.So you can find,this technique of water fracturing in low permeability reservoirs fracturing foreground is very good,it can be said that the advantage of clear water fracturing is very obvious,for the effective development of low permeability reservoir,it can play the role of a technical support. |
