Description
Technical Field
The invention relates to the technical field of tertiary oil recovery in oil fields, in particular to a skid-mounted polymer dry powder quick dissolution curing device, and particularly relates to a skid-mounted polymer dry powder quick dissolution curing device for converting polymer dry powder for oil fields into cured mother liquor.
Background
The oil field is non-renewable from exploitation to end of underground resources, the whole process is mainly divided into a natural energy exploitation stage (self-injection), a secondary (water flooding) oil exploitation stage and a tertiary (polymer) oil exploitation stage, each stage has an economic exploitation limit, when the limit is reached, the benefit gradually worsens with time until no benefit exists, particularly the high water content period in the later stage of secondary oil exploitation is entered, and the benefit gradually worsens with the reduction of underground resources until no economic value exists. To further enhance recovery, it was found that more subsurface residual oil could be efficiently recovered after polymer injection, whereupon the field entered a three (polymer) recovery stage. Before tertiary oil recovery injection is carried out, the polymer dry powder is converted into an injectable cured polymer mother solution, the polymer dry powder is converted through a series of physical processes such as dispersion, dissolution, stirring, curing and the like in water, so that the injection standard finished polymer mother solution can be achieved, and in order to achieve the aim, the oil field needs to take land to construct an injection allocation station, install more treatment equipment and arrange more personnel, so that the polymer dry powder can be converted into the oilfield injected cured polymer mother solution, and a great deal of cost is required to be input; meanwhile, by adding the polymer with low price, the system cost of the polymer tertiary oil recovery is greatly increased, and especially in the period of low price of world petroleum and under the condition that the recovery rate of the polymer tertiary oil recovery is not further improved, the cost is reduced when the oil field wants to economically and effectively adopt the polymer tertiary oil recovery, so that the cost is a key for the oil field to further develop the polymer production, and the benefit is a key for the technology, especially for whether the marginal oil field can develop the polymer tertiary oil recovery.
In order to overcome the defects that the injection allocation station and the polymer continuous curing device used in the tertiary oil recovery technology have large equipment investment and large occupied area, and the tertiary oil recovery of the polymer cannot be carried out due to limited field, the skid-mounted polymer curing device is produced.
Chinese patent application publication No. CN202113815U and application No. CN201120155995.0 disclose a skid-mounted polymer continuous curing device. Although the curing device adopts a skid-mounted structure to reduce the tertiary oil recovery cost of the polymer to a certain extent, the working process of the skid-mounted polymer continuous curing device is that working water enters a water inlet pipe and enters a mixer after being metered by a flowmeter; meanwhile, the polymer dry powder metered by the metering feeder enters a hopper and is primarily mixed with water in a mixer; the mixed polymer solution enters a curing tank, and the polymer solution in each curing tank is stirred and cured by a stirrer for 90-120 minutes and then is output by a liquid outlet pipe to complete curing of polymer dry powder. However, before the skid-mounted polymer continuous curing device is stirred and cured by the curing box, polymer powder and water are primarily mixed by a mixer, and water and polymer dry powder particles cannot be uniformly dispersed in the primary mixing process, so that the polymer and the water are easily bonded into blocks in the primary mixing process to influence the quality of a finished product. And the polymer dry powder particles can be rapidly dissolved and expanded on the outer surface after being mixed with water, and soft coats (colloid) attached to the outside of the polymer particles are dissolved to isolate hard cores in the polymer particles from water, so that the polymer dry powder particles cannot be fully dissolved, the dissolution rate of the polymer is seriously reduced, and the curing time of the polymer is greatly prolonged.
Chinese patent application publication No. CN110026099a and application No. CN201910476414.4 discloses a quick dissolving device for skid-mounted oil extraction auxiliary agent. The discharge port of the dry powder storage tank of the dissolving device is communicated with the feed port of the water-powder mixing device through a dry powder metering screw. The water-powder mixing device is composed of a material distribution tank, and a material distribution motor is fixed on the upper cover of the material distribution tank. The output shaft of the material distribution motor is in transmission connection with a stirring shaft arranged in the inner center of the material distribution tank through a belt, a material distribution throwing disc is fixed at the bottom end of the stirring shaft, more than one layer of material distribution thin rods are arranged above the material distribution throwing disc, a dry powder feeding pipe penetrates through an upper cover and is arranged on the material distribution thin rods in the material distribution tank, a water distribution pipe is fixed on the periphery of an upper opening of the material distribution tank, and a plurality of water distribution spraying holes are formed in the water distribution pipe and face the inner wall of the tank body. The dry powder and the incoming water are uniformly mixed in the equipment, the dry powder is fully contacted with the water, and the dry powder is cut, dispersed and coagulated under the action of centrifugal force in the forward and reverse directions. However, the polymer dry powder particles mixed with water can be cut by a cloth fine rod after the surface of the polymer dry powder particles is expanded, so that the molecular structure of the polymer is damaged, and the viscosity of a polymer mother solution finished product is affected and cannot reach the standard.
In summary, the existing skid-mounted polymer curing device has the problems that the polymer and water are easily bonded into blocks in the primary mixing process to influence the quality of the finished product, the dissolution rate of the polymer is low, the curing time of the polymer is long, the molecular structure of the polymer is easily damaged, and the viscosity of the finished product of the polymer mother liquor is influenced.
