Description
Technical Field
The utility model relates to the technical field of oilfield chemical flooding development, in particular to a non-packaging dry powder storage and dispersion integrated device.
Background
Chemical flooding is a main mode for greatly improving recovery efficiency of victory oil fields. At present, 65 chemical flooding projects are implemented, the geological reserve is covered with 5.0 hundred million tons, the accumulated oil is 6649 ten thousand tons, the accumulated oil is 3141 ten thousand tons, and the recovery rate is improved by 6.26 percent. The polymer is the main oil displacement agent, and 1300 tons of polymer and 3 tons of polymer dry powder are injected every year.
The main process of the chemical flooding injection system consists of three links of polymer dry powder storage, transportation, dispersion and dissolution, sewage treatment, mixing and injection. At present, a fixed station mode is generally adopted for preparing and conveying polymer mother liquor: clear water is adopted for centralized preparation of mother liquor, and then the mother liquor is delivered to each injection polymerization station, so that the mother liquor is high in viscosity and strong in stability, and the technology is mature, and is suitable for large-scale projects which need to be prepared by a clear water source.
The main problem existing at present is that the storage, dispersion and dissolution of polymer dry powder are not suitable for the current situation requirements: (1) The polymer dry powder is stored and transported, and the polymer dry powder which is used for chemical driving at present is packaged by a small bag of 25kg in an oil extraction factory, transported by a truck on site, manually carried and stored in a storage room. The problems of large occupied area of a storage room, large labor intensity of staff transportation, hardening of powder and the like exist. And (2) adding polymer dry powder, and adding materials into a small packaging bag: the small bags of 25kg are required to be manually carried, automatically broken and discharged, and the waste bags are recovered. The labor intensity of workers is high, dust harm and the recycling difficulty of packaging bags are high, and environmental protection and dust occupational health risks exist. (3) The polymer dry powder is dispersed and cured, the technology of the existing dispersion curing device is mature, but the problems of low precision of manual powder correction and discharging, large occupied area of equipment, high manufacturing cost and the like exist in manual operation feeding.
With the comprehensive promotion of the improvement of the system mechanism of the oil company, the total amount of workers of first-line workers of the oil extraction factory is greatly reduced; the personnel in the injection station are sharply reduced to 10 persons from 60 persons, and the automation degree of the storage and preparation links of the polymer dry powder is low. How to utilize advanced equipment to realize automation of polymer dry powder storage, dispersion and dissolution becomes a problem to be solved in the present day.
Therefore, the integrated device for storing and dispersing the unpackaged dry powder is developed, and the problems of large occupied area, high investment cost, high labor intensity, inaccurate feeding, dust occupational hazard, waste bag environmental pollution and the like existing in the polymer dry powder packaged by the 25kg small bag used at the present of a chemical flooding centralized preparation station are solved.
State of the art dry powder storage and transportation at home and abroad and development trend:
1. the Daqing oilfield adopts 750Kg package, and is fully-automatic in a feeding and conveying system (matched with a aviation crane, belt conveying, automatic bag breaking, screw lifting, dust removing device and the like; advantages are high in automation degree, low in labor intensity of workers, high in investment, and high in disposal difficulty of damaged packaging bags, besides a large factory building (9 m in height, 20 m in width and 30 m in length) is required, and matched with 260 ten thousand yuan/set of equipment is required.
2. Depending on engineering requirements and conditions, shipping packages can offer a variety of ways: (1) manually cutting the small bag; (2) hoisting ton bags; (3) container+silo; (4) silo sledge blocks. The mode of the container and the silo has the advantages of small occupied area, convenient operation and no package.
State of the art dry powder dispersion at home and abroad and development trend:
air-assisted dispersing and dissolving device, which is a common dispersing technology at 90 s at home and abroad, has the disadvantage of air-assisted: the process is complex, the equipment occupies large area and the manufacturing cost is high.
At present, a dispersing technology, namely water jet type dispersing and mixing is commonly used. Water jet type advantage: simple process, small occupied area of equipment and low cost. Disadvantages: (1) preparing mother solution with concentration less than 6000ppm; (2) a plurality of curing tank groups are matched for alternate dissolution; (3) dispersing and dissolving the whole contact air.
The prior art is greatly different from the utility model, and the technical problem to be solved by the utility model is not solved, so that a novel packaging-free dry powder storage and dispersion integrated device is invented.
