Method for injecting oil displacing agent into oil reservoir to improving oil recovery by using fracturing
ActiveCN106837274AReduce penetrationLess corrosiveFluid removalDrilling compositionViscosityPetroleum engineering
The invention relates to a method for injecting oil displacing agent into an oil reservoir to improve oil recovery by using fracturing. The method for injecting the oil displacing agent into the oil reservoir to improving oil recovery by using fracturing mainly solves the problems of large viscosity loss and low injection efficiency during the injection process of the existing three kinds of oil reservoir oil displacement agents. The method for injecting the oil displacing agent into oil reservoir to improving oil recovery by using fracturing is characterized in that (1) dividing a target stratum to the well fracturing section; (2) determining a half fracture length for the well fracturing section of the target stratum; (3) determining the oil displacement agent dosage for the well fracturing section of the target stratum; (4) determining a construction displacement the well fracturing section; (5) determining construction procedure of a pumping injection; and (6) mixing and injecting the oil displacement agent. The method for injecting the oil displacing agent into oil reservoir to improving oil recovery by using fracturing can greatly improve the injection efficiency and reduce the displacement efficiency loss, thus greatly improve the recovery efficiency and single well production.

The invention provides a sand-flushing and well-dredging method, which is carried out by adopting a sand-flushing and well-dredging device, and the sand-flushing and well-dredging method comprises thefollowing steps of: 10, putting a sand-flushing and well-dredging device into a set position in a well and carrying out sand detection operation; 20, connecting the sand-washing and well-dredging device with a cement tank car for sand flushing operation, and lifting the sand-washing and well-dredging device to an upper boundary set position of an oil layer after the sand flushing is finished; 30,throwing balls into a central pipe to pressurize, wherein a pressing driving component can drive a frustum body to taper into a reducing sleeve and increase the diameter of the reducing sleeve; 40, lowering a detection pipe column to an artificial well bottom, and detecting the casing condition between the artificial well bottom and the upper boundary of the oil layer; 50, after the detection isfinished, lifting the sand-washing and well-dredging device, when the lifting is blocked, increasing the lifting pulling force to reset the frustum body, so that the diameter of the reducing sleeve isrestored, and lifting the sand-washing and well-dredging device to the ground at the moment. According to the invention, the sand-flushing and well-dredging process can be completed by carrying out one-time pipe column lifting operation, so that the labor intensity of workers can be reduced, and the production time is improved.
