A non-flowback fracturing-oil flooding integrated oilfield stimulation method |
| abstract |
The invention relates to a non-flowback fracturing-oil flooding integrated oilfield stimulation method. The method includes the following steps: dissolving the modified cellulose products in water of oil field fracturing and higher purity; adding salts whose metal ions account for 5-20% of the mass fraction of the modified cellulose products; adding fracturing into the water sand; add a breaker to the above mixing system; use conventional fracturing means to pump the resulting mixture into the formation and follow up with an aqueous solution containing catalyst as a displacement fluid. The method does not generate fracturing flowback fluid, avoids the treatment of waste water, and at the same time, the fracturing fluid is converted into an oil-displacing agent after moderately breaking the gel, which can improve the oil-displacing effect and reduce the cost of fracturing and oil-displacing. |
