Description
Technical field
The utility model relates to petroleum drilling technology field, the injected system that particularly a kind of particle punching drilling is special.
Background technology
In recent years, along with the needs of deep formation exploration and development, particle impact drilling technology more and more receives concern, and each elephant and universities and colleges have all carried out corresponding research work.This technology is different from traditional drilling technology, its cardinal principle is in drilling fluid, be filled with a certain amount of metallic, after being accelerated by special drill bit, utilize the broken bottom rock of the impact force of metallic, and recycle after metallic returns out ground with drilling fluid.
As the chief component of particle impact drilling technology, the quality of the injected system that particle punching drilling is special directly determines the success or failure of whole technology.The special injected system of traditional particle punching drilling mainly utilizes the deadweight of metallic, the negative pressure produced by drilling liquid flow by metallic " absorption " in drilling fluid, which structure is simple, but effectively can not control injection rate and the injection rate of metallic, the alluvial of easy generation metallic in-line, drilling fluid is flowed in pipeline not smooth, even cause the blocking of bit port, bring out the situations such as down-hole complexity, therefore, which cannot meet particle and the mixed uniformly requirement of drilling fluid, also the effect of particle impact drilling technology is had a strong impact on.
Summary of the invention
Technical problem to be solved in the utility model overcomes the existing injected system existed in background technology to inject uneven, the uncontrollable problem of injection rate, and the injected system providing a kind of particle punching drilling special, the injected system that this particle punching drilling is special, can regulate as requested, control the injection rate of whole metallic, thus realize metallic and mix with the effective of drilling fluid, meanwhile, the content of metallic in drilling fluid can be regulated.
The invention for solving the technical problem reaches by following technical scheme: the injected system that this particle punching drilling is special, comprises particle storage tank, and described particle storage tank bottom pipeline connects injection pump entrance, and injection pump outlet connects drilling fluid pipeline; Described particle storage tank tank deck injects pipeline by particle and connects relay pump, and relay pump connects particle transfer tank; Described particle injects on pipeline, particle storage tank bottom pipeline and connects hydraulic operated valve respectively; Bonding pressure sensor on described particle storage tank tank deck side.
The special injected system of this particle punching drilling mainly utilizes special particle injection pump to carry out mixing of particle and drilling fluid, in particle punching drilling system, first corresponding numerical value is set by control centre, open system carries out particle injecting program, in running, can according to the actual conditions at scene, amendment relevant parameter, manual input parameter in the corresponding software panel of the heart in the controlling, thus the running status of adjustment injection pump, thus realize accurately controlling particle injection rate, meet particle and the mixed uniformly object of drilling fluid, reach the technical requirements of particle punching drilling, effectively prevent because the uncontrollable of particle injection causes pipeline to block or drill bit blocking, the situations such as even down-hole is complicated, affect the effect of particle impacting.
The utility model can have following beneficial effect compared with above-mentioned background technology: the injected system that this particle punching drilling is special, the injection rate of particle can be controlled, thus the content of adjustment particle in drilling fluid, the object of reach Homogeneous phase mixing, steadily creeping into, meets on-the-spot instructions for use.

Accompanying drawing 1 is system architecture schematic diagram of the present utility model.
In figure: 1-relay pump, 2-particle transfer tank, 3-particle inject pipeline, 4-hydraulic operated valve, 5-particle storage tank, 6-pressure sensor, 7-injection pump, 8-drilling fluid pipeline.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the injected system that this particle punching drilling is special, comprises particle storage tank 5, and described particle storage tank 5 tank bottom tube line connects injection pump 7 entrance, and injection pump 7 exports and connects drilling fluid pipeline 8; Described drilling fluid pipeline 8 connects borehole pump; Described particle storage tank 5 tank deck injects pipeline 3 by particle and connects relay pump 1, and relay pump 1 connects particle transfer tank 2; Described particle injects on pipeline 3, particle storage tank 5 tank bottom tube line and connects hydraulic operated valve 4 respectively; Bonding pressure sensor 6 on described particle storage tank 5 tank deck side.
Described particle transfer tank is the temporary place of particle, and Main Function is convenient to particle relay pump the intact particle in tank is injected particle storage tank by injecting pipeline; Particle storage tank is the storage of particle, belongs to high-pressure bottle.Particle is stored in after particle storage tank reaches design flow, closes the hydraulic operated valve on storage tank top, carries out pressurized treatments, and utilize the monitoring of pressure sensor to make the pressure in tank equal with outside drilling fluid line pressure, thus be the startup create environment of particle injection pump.
Injection pump is the device of conveying particle, when creeping into, open the hydraulic operated valve of storage tank bottom, injection pump is utilized to be injected in outside drilling fluid pipeline by uniform particle, make particle arrive shaft bottom with drilling fluid, realize particle punching drilling, this device adopts hermetic design, can high pressure be born, hydraulic motor is installed as drive part.In the running, its state is controlled by control centre completely, and control centre is configured with parameters input interface, can manually input concrete numerical value, carry out the manual adjustments of injection pump, thus better controls the operation of injection pump, meets the demand of onsite application.
The special injected system of this particle punching drilling mainly utilizes special particle injection pump to carry out mixing of particle and drilling fluid, in particle punching drilling system, first corresponding numerical value is set by control centre, open system carries out particle injecting program, in running, can according to the actual conditions at scene, amendment relevant parameter, manual input parameter in the corresponding software panel of the heart in the controlling, thus the running status of adjustment injection pump, thus realize accurately controlling particle injection rate, meet particle and the mixed uniformly object of drilling fluid, reach the technical requirements of particle punching drilling, effectively prevent because the uncontrollable of particle injection causes pipeline to block or drill bit blocking, the situations such as even down-hole is complicated, affect the effect of particle impacting.
