Abstract
The invention discloses a powder conveying hopper which comprises a hopper body, a proportional valve, a control system and a connecting cable. The proportional valve is formed by small holes capable of achieving size adjustment. According to the powder conveying hopper, blocking agent powder is quantitatively added by adjusting the small holes in the proportional valve, so that the profile control process can be conducted under controllable conditions, the production efficiency of the profile control technology is improved, and the increase of oil production is effectively accelerated.
Description
Technical field
The present invention relates to field of oil field oil extraction, be specially a kind of defeated powder funnel.
Background technology
During the profile control of oil field, blocking agent solution plays vital effect.In practice of construction process, be generally place a funnel on stirred pot, blocking agent powder is transported on stirred pot by operating personal, then be poured in funnel, from funnel, blocking agent powder slowly flows in profile control water, and motor stirs profile control water, and blocking agent powder could dissolve.
In profile control process, the addition of blocking agent powder needs strict control, could realize the profile control effect of expecting, the funnel of prior art, can only play reinforced effect, cannot realize quantifying feed, profile control effect is affected, is unfavorable for the raising of oil recovery production efficiency.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention discloses a kind of defeated powder funnel, achieving the accurate control of blocking agent powder addition, improve the production efficiency of profile control technology.
The technical solution used in the present invention is as follows:
A kind of defeated powder funnel, comprise funnel body, proportional valve, control system and connection cable, described proportional valve is made up of the aperture of adjustable size.
Preferably, the quantity of described aperture is 4.
In practice of construction process, according to the amount of required blocking agent powder, by open area and the open hour of aperture on control system adjustment quantitative valve, then blocking agent powder is poured in defeated powder funnel by operating personal, wait to arrive Preset Time, aperture is closed automatically, then achieve quantitatively adding of blocking agent powder.
Beneficial effect of the present invention: by the aperture on adjustment quantitative valve, achieves quantitatively adding of blocking agent powder, profile control process is carried out in controlled conditions, improves the production efficiency of profile control technology, effectively facilitate the raising of oil production.
Accompanying drawing explanation
Fig. 1 is a kind of defeated powder funnel
1-funnel body; 2-proportional valve; 3-control system; 4-connection cable; 5-aperture.
Detailed description of the invention
With reference to the accompanying drawings, embodiments of the present invention are illustrated.
A kind of defeated powder funnel, comprise funnel body 1, proportional valve 2, control system 3 and connection cable 4, described proportional valve 2 is made up of four apertures 5 of adjustable size.
In work progress, according to the amount of required blocking agent powder, by open area and the open hour of aperture 5 on control system 3 adjustment quantitative valve 2, then blocking agent powder is poured in defeated powder funnel by operating personal, wait to arrive Preset Time, aperture 5 is closed automatically, then achieve quantitatively adding of blocking agent powder.
Claims (2)
1. a defeated powder funnel, comprises funnel body, proportional valve, control system and connection cable, it is characterized in that, described proportional valve is made up of the aperture of adjustable size.
2. defeated powder funnel according to claim 1, is characterized in that, the quantity of described aperture is 4.
