Description
Technical field
The utility model relates to a kind of particle impacting drilling well injection device, belongs to oil exploration and development fields.
Background technology
The most advanced both at home and abroad at present steel grit injection device by the exploitation of U.S. particle percussion drilling technology company is too complicated, consumable accessory is many, control is difficult, most tests are all ended because of injection device breaks down, reliability is not resolved, facts have proved that it can not satisfy the successional requirement of particle impacting drilling well well.
In addition, both at home and abroad through 40 years of researches, although successively developed abrasive material injection devices such as orifice plate, supercharging funnel, main flow shunting, accumulator transmission, piston transmission, motor or the control of pump control capsule, but because can not avoid being with gas, introduce other liquid, problem such as injection rate is uncontrollable, therefore, all can not be used for the particle impacting drilling well, above-mentioned situation has seriously restricted the commercialization process of particle impacting drilling technology, and the utility model can address this problem well.
Summary of the invention
Because above-mentioned domestic and international abrasive material injection device exists and can not avoid being with gas in the injection process, introduce other liquid, shortcomings such as injection rate is uncontrollable are with not enough, therefore they all can not be used for injecting particle impacting drilling well steel grit well, Given this, the utility model is used for reference domestic and international 40 years of researches achievements, in conjunction with the actual condition of oil drilling and the technical characterstic of particle impacting drilling well, research has formed a kind of new particle impacting drilling well steel grit injection device, and the purpose of this utility model is to provide a kind of reliable particle impacting drilling well steel grit injection device for the scene.
A kind of particle impacting drilling well injection device of the present utility model comprises ground high voltage charge line, bypass line control valve, bypass line, steel grit holding vessel, surges (or manually) charging valve, holding vessel blowdown line, holding vessel pressure release control valve, steel grit, screw propeller, steel grit injection control valve, high-impact erosion current-limiting apparatus and borehole pump.Described current-limiting apparatus is arranged on after the bypass line, and the bypass line control valve is arranged between ground high voltage charge line and the steel grit holding vessel, and holding vessel pressure release control valve is between steel grit holding vessel and drilling fluid pot; Described screw propeller is positioned under the steel grit holding vessel, and the steel grit injection control valve is between screw propeller and ground high voltage charge line.
Screw propeller is for adopting the high-pressure spiral pusher of special seal structure, is arranged under the steel grit holding vessel, on the steel grit injection control valve.
Current-limiting apparatus is arranged on after the bypass line, before the steel grit injection control valve.
The utility model one be simple in structure, reliability is high, the 2nd, can realize injecting equably continuously, the 3rd, the steel grit injection rate is controlled, adjustable, the 4th, gas or other non-drilling fluid liquid can be injected in the drilling fluid in the injection process.

The specific embodiment
Now the utility model will be further described in conjunction with Figure of description.
Comprise in the accompanying drawing left and right two covers identical, separately function independent, can realize the injection device that is used alternatingly.When adopting the utility model to carry out the particle impacting drillng operation, the first step is opened (or the manually) charging valve 5 that surges that is positioned at steel grit holding vessel 4 tops, left side, steel grit 8 is joined in the steel grit holding vessel 4, fill it up with and using drilling fluid toward steel grit holding vessel 4 by drilling well circulating device low-pressure line, steel grit 8 interstitial air in the emptying steel grit holding vessel 4 are closed (or the manually) charging valve 5 that surges.Second step was opened bypass line control valve 2, made steel grit holding vessel 4 reach consistent with the pressure of ground high voltage charge line 1.The 3rd step was opened steel grit injection control valve 10, started screw propeller 9 then, the injection of beginning steel grit.
Steel grit 8 in left-hand unit steel grit holding vessel 4 injects and finishes, and enables the injection device that is positioned at the right side according to above-mentioned steps.Meanwhile, stop to be positioned at the screw propeller 9 of left-hand unit, close the steel grit injection control valve 10 and the bypass line control valve 2 of left-hand unit, open holding vessel pressure release control valve 7, atmospheric pressure is arrived in the pressure pressure release of steel grit holding vessel 4, open (or the manually) charging valve 5 that surges, steel grit 8 is joined in the steel grit holding vessel 4, treat that steel grit 8 injections in the right side injection device steel grit holding vessel 4 finish, and reactivate.
Said process alternately repeats, and just can realize continuously, steel grit is injected in the drilling well ground high pressure line 1 equably, thereby realize the particle impacting drilling well.
