| Fracturing fluid is an important part of the fracturing technology is the key to the success or failure of the fracturing,along with the development of The Times,has gone through a oil base fracturing fluid,fracturing fluid system polymer crosslinked fracturing fluid,foam fracturing fluid and viscoelastic surfactant fracturing fluid four development stages of change. And high efficiency,low damage,low cost,is the developing direction of fracturing fluid technology,is a primary problem of fracturing fluid,the present research in this paper,combining with the development of fracturing fluid system at home and abroad, and the problems now fracturing fluid.To solve these problems appeared a new kind of fracturing fluid and field application in tuha oilfield, based on efficient crosslinking fracturing fluid abroad and comparative study on the performance of polymer fracturing fluid system, the analysis of tuha oil field fracturing fluid to reservoir damage and fracture diverting capacity reason, the research of low damage fracturing fluid system is determined key: reduce the residue content, reduce the amount of filtration, gel breaking performance, improve the fracturing fluid and reservoir and formation fluid compatibility. Through a lot of theoretical analysis and laboratory experiments, some suitable for reservoir characteristics of tuha oilfield new low damage fracturing fluid system, the field test results show that with conventional fracturing liquid ratio, the new fracturing fluid system for low permeability reservoir fracturing measures more effective. |
