Description
Technical field
The utility model relates to oil and gas drilling technique field, relates more specifically to a kind of device evaluating air drilling water-absorption particle water rem oval.
Background technology
Although air drilling drilling speed is fast, lost circulation prevention, available protecting reservoir, when formation water output, the application of gas drilling is just restricted.After formation water output, bore hole annulus humidity increases, and the solid particle of annular space high speed migration absorbs moisture, forms large aggregated particle gradually, and blocking inventionannulus flow passage, more serious may block annular space, causes the major accident such as bit freezing, mud drum to occur.After gas drilling formation water output, need to take the measure of dewatering, in annular space high velocity air, add water-absorption particle is a kind of water-eliminating method preferably.But water-absorption particle water rem oval is difficult to determine, in removal process, the consumption of water-absorption particle is also difficult to calculate, and the water removal effect of well can not ensure.Therefore, if a kind of device evaluating air drilling water-absorption particle water rem oval can be invented, just can carry out effective evaluation to the water-absorption particle adopted, reach best water removal effect with minimum water-absorption particle.
Summary of the invention
The purpose of this utility model is: provide a kind of device evaluating air drilling water-absorption particle water rem oval.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of device evaluating air drilling water-absorption particle water rem oval of the utility model, comprises blower fan, gas meter, draft tube, charging aperture, humidifier, hygrometer, compressed screens, fixed block, wireway, surge drum, support.Draft tube is connected with blower fan and wireway respectively, and draft tube is provided with gas meter, and charging aperture is arranged on wireway air intake opening upper end.Be connected by wireway between humidifier with compressed screens, in humidifier front end, hygrometer be installed.Compressed screens is positioned in wireway, is provided with fixed block on the left of it.Gathering barrel is positioned over wireway exit, and support installing is in wireway bottom.Open humidifier, regulate humidity value, then open Fan Regulation gas injection rate, and then add water-absorption particle from charging aperture, water-absorption particle is under the drive of high velocity air, move along wireway, behind the region on the left of compressed screens, absorb moisture, finally enter into gathering barrel, by measuring the changing value of weight before and after water-absorption particle, the water-taking efficiency of this water-absorption particle under a certain humidity value, a certain movement velocity just can be obtained.
The utility model advantage: structure is simple, easy to operate, comparatively accurate to the evaluation of water-absorption particle water rem oval.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation evaluating the device of air drilling water-absorption particle water rem oval of the utility model.
Fig. 2 is A-A sectional view in Fig. 1.
In figure: 1. blower fan, 2. gas meter, 3. draft tube, 4. charging aperture, 5. humidifier, 6. hygrometer, 7. compressed screens, 8. fixed block, 9. wireway, 10. gathering barrel, 11. supports.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of device evaluating air drilling water-absorption particle water rem oval of the utility model, forms primarily of blower fan 1, gas meter 2, draft tube 3, charging aperture 4, humidifier 5, hygrometer 6, compressed screens 7, fixed block 8, wireway 9, gathering barrel 10, support 11.Blower fan 1 injects high velocity air in draft tube (3), gas meter 2 is for showing gas inject speed, draft tube 3 adopts pressure hose to make, and charging aperture 4 is used for adding water-absorption particle in wireway 9, and humidifier 5 is for regulating the humidity of air in compressed screens 7, hygrometer 6 is for showing humidity value, fixed block 8 is for fixing compressed screens 7, and compressed screens 7 is used for simulating pore type stratum, and wireway 9 transparent PVC pipe is made, be convenient to observation experiment phenomenon, gathering barrel 10 is for collecting
Wireway 9 exports the water-absorption particle of discharging, and support 11 is arranged on wireway 9 bottom, supports whole device.Open blower fan 1, utilize gas meter 2 to regulate air injection rate, after steady air current, open humidifier 5, regulate the humidity in compressed screens 7 by hygrometer 6.After gas injection speed and humidity reach requirement of experiment, add except particle water from charging aperture 4, except particle water just moves along wireway 9 under the drive of high velocity air, absorb the moisture on the left of compressed screens, finally arrive gathering barrel 10 inner.After having tested, calculate the weight change before and after water-absorption particle experiment, just can obtain the water rem oval of this kind of water-absorption particle under a certain humidity and a certain air injection rate condition.This apparatus structure is simple, easy to operate, and evaluation effect is comparatively accurate, is conducive to the water rem oval after improving air drilling formation water output, ensures carrying out smoothly of air drilling.
