Description

Technical Field

[0001] The invention belongs to the field of petroleum exploitation and transportation, and relates to a high-efficiency self-generated foam fluid generating device with controllable performance. Background Art

[0002] In the field of oil extraction, for low permeability oil and gas reservoirs, the use of oil-resistant and temperature-resistant self-generated foam fracturing and acidizing construction is one of the effective transformation methods, and the use of foam flooding is also an important technical measure to improve the recovery rate in the process of exploitation of low permeability and ultra-low permeability reservoirs; in the field of oil transportation, my country's heavy oil resources are very rich and have huge development potential, but the high density, high viscosity and low fluidity of heavy oil bring great difficulties and challenges to its exploitation and transportation. The use of oil-resistant and temperature-resistant self-generated foam system can achieve good effects of boundary lubrication and drag reduction of thermal heavy oil flow. Related research has become a hot research direction in academia. Through practice, it is found that the performance of oil-resistant and temperature-resistant foam will affect the drag reduction effect of hot heavy oil in underground production and pipeline transportation. Foams of different qualities have different drag reduction effects on hot heavy oil in oil extraction and pipeline transportation.

[0003] Oil-resistant and temperature-resistant self-generated foam, that is, adding a foaming agent, a foam stabilizer and an aerator, can automatically generate foam at a suitable temperature. Since room temperature cannot meet the optimal temperature for foam self-generation, the current method for preparing this type of foam indoors is to first heat the water, use a temperature sensor to monitor the water temperature, and when the optimal reaction temperature of the foaming agent, the foam stabilizer and the aerator is reached, the foaming agent, the foam stabilizer and the aerator are added to the barrel in turn and stirred until they are completely dissolved. When all the preparation materials are dissolved and the foam base liquid is prepared, the foam base liquid is used to self-generate foam, and the self-generated foam system for thermal recovery heavy oil drag reduction is generated.

[0004] At present, the indoor self-generated foam fluid generating device is not perfect. The heating, stirring and foam generating processes often cannot be satisfied by machines at the same time. The heating, stirring and foam generating processes of the foam base liquid raw materials all require manual intervention, which leads to the waste of a lot of time in the foam preparing process, incomplete dissolution of the foam base liquid raw materials in the foam preparing process, and further waste of the foam preparing raw materials. In addition, the gas content of the foam cannot be controlled during the foam generating process, and the quality distribution of the generated foam is uneven. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a high-efficiency self-generated foam fluid generating device with controllable performance.

[0042] The internal structure of the foam generator is shown in Figures (10) and (11). The foam generator is composed of a foam generator shell (37), a first baffle plate with holes (38), a second baffle plate with holes (40), a plurality of groups of foaming holes (41) and a plurality of groups of flow guide pipes (39). The right end of the foam generator shell (37) is connected to the second liquid discharge pipe (36). A first baffle plate with holes (38) is provided inside the shell near the second liquid discharge pipe (36). There are a plurality of groups of foaming holes (41) on the baffle plate. The foaming hole (40) is provided with a hole outer edge flange (41), the hole outer edge flange (42) extends from the edge of the foaming hole (41) in a direction parallel to the axis of the foaming hole (41), and the inner circle diameter of the flange smoothly extends outward and increases, the extension direction of the hole outer edge flange (42) of the plurality of groups of foaming holes (41) is the same as the flow of the foam fluid, and the plurality of groups of guide pipes (39) are respectively connected to the corresponding foaming holes (41) between the first baffle plate with holes (38) and the second baffle plate with holes (40).

[0043] When in use, first connect the power socket (17) to the power supply, turn on the switch and the temperature control console (15) to set the heating temperature, then the heating base (14) starts to heat the water added with the raw materials for preparing the foam base liquid in the stirring barrel (3), and starts the stirring drive motor (4), then the stirring shaft (5) drives the two sets of stirring blades (6) to rotate, stirring the base liquid in the barrel, and the temperature sensor (7) at the bottom of the shaft feeds back the temperature of the foam base liquid in the stirring barrel (3) to the LED temperature display screen (16) in real time. When the foam base liquid is heated to the set temperature and stirred continuously until the raw materials for preparing the foam base liquid are completely dissolved in the water, the foam base liquid is prepared, and the heating and stirring are stopped. The first liquid discharge valve (12) is opened, and the foam base liquid in the mixing barrel (3) flows into the pump inlet pipe (21) and the centrifugal pump (22) through the first liquid discharge pipe (13), and is then pumped by the centrifugal pump (22) to the pump outlet pipe (23) and the T-shaped pipe (26).

The tube (39) continuously generates foam, which then flows out from a plurality of foaming holes (41) on the second perforated baffle (40). The foaming holes (42) are all provided with outer edge flanges (42), the extension direction of the flanges is the same as the foam flow direction, and the inner circle diameter of the flanges smoothly extends outward and increases, which significantly reduces the contact area between the bubbles and the perforated baffle, so that the bubbles can more easily detach from the perforated baffle during the formation and expansion process, shortening the time for foam generation and detachment, thereby enabling the foam generator to generate new bubbles faster, effectively improving the foaming speed.

[0044] After the foam preparation is completed, the stirring barrel (3), stirring shaft (5) and stirring blade (6) of the heating and stirring system need to be cleaned. At this time, the nozzle (9) of the cleaning mechanism is connected to an external water pump or a faucet and turned on.

A highly efficient self-generated foam fluid generating device with controllable performance as claimed in claim 5, characterized in that: The outer edge flange (42) of the hole extends from the edge of the foaming hole (41) in a direction parallel to the axis of the foaming hole (41), and the inner circle diameter of the flange smoothly extends outward and increases. The extension direction of the outer edge flange (42) of the plurality of groups of foaming holes (41) is the same as the flow direction of the foam fluid. The outer edge flange (42) of the hole is designed on the plurality of groups of foaming holes (41) to significantly reduce the contact area between the bubbles and the first perforated baffle (38) and the second perforated baffle (40), so that the bubbles can more easily separate from the foaming holes (41) during the formation and expansion process, shortening the time for foam generation and separation, and achieving high foam generation efficiency.
