Description
Technical field
The utility model relates to petroleum drilling technology field, particularly a kind of particle injected system.
Background technology
In recent years, creep into demand along with deep hard formation, particle impact drilling technology, as the robust techniques realizing hard formation fast drilling, more and more receives the concern of each side.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, treat that metal returns out ground with drilling fluid and recycles.Particle injected system is as an important ingredient, and its efficiency is directly connected to the mixing quality of particle and drilling fluid, also determines the success or failure of whole particle well system.
Current injected system 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, make drilling fluid smooth in pipeline flowing, even cause the blocking of bit port, bring out the situations such as down-hole complexity.Meanwhile, existing injected system automaticity is low, cannot complete Automatic Control, and procedure connection is slow, makes down-hole particle impacting be in state off and on, causes whole system efficiency to decline, had a strong impact on the effect of particle impact drilling technology.
Summary of the invention
Technical problem to be solved in the utility model overcomes the conventional particle injected system existed in background technology injection rate cannot be regulated can not to reach the problem of mixed uniformly technical requirements, and a kind of particle injected system is provided, this particle injected system, the autonomous operation of whole system can be carried out, reduce the interference of human factor, improve the operational efficiency of system greatly, realize particle and drilling fluid effective, steady, mix uniformly.
The invention for solving the technical problem reaches by following technical scheme: this particle injected system, comprises borehole pump, particle storage tank, and described borehole pump connects drilling well surface line, and drilling well surface line connects particle storage tank abhiseca side by pressure-equalizing line; Particle storage tank abhiseca opposite side connects overflow tank by overflow line; Described particle storage tank abhiseca portion connects particle charge pipe; Described pressure-equalizing line, particle charge pipe, overflow line are connected to respectively hydraulic operated valve A, hydraulic operated valve B, hydraulic operated valve C; Described particle storage tank is filled with bottom and is connected particle injection pump, and particle injection pump connects drilling well surface line by pipeline.
The utility model can have following beneficial effect compared with above-mentioned background technology: this particle injected system is owing to adopting said structure, by automatically controlling the action of whole system all devices and parts, control the injection rate of particle, and the adjustment of particle injection rate can be carried out as requested, the object of realize Homogeneous phase mixing, steadily creeping into, improve the operational efficiency of particle injected system, meet on-the-spot instructions for use.

detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this particle injected system, comprises borehole pump 1, particle storage tank 9, and described borehole pump 1 connects drilling well surface line 11, and drilling well surface line 11 connects particle storage tank 9 abhiseca side by pressure-equalizing line 2; Particle storage tank 9 abhiseca opposite side connects overflow tank 8 by overflow line 7; Described particle storage tank 9 abhiseca portion connects particle charge pipe 6; Described pressure-equalizing line 2, particle charge pipe 6, overflow line 7 are connected to respectively hydraulic operated valve A3, hydraulic operated valve B4, hydraulic operated valve C5; Described particle storage tank 9 is filled with bottom and is connected particle injection pump 10, and particle injection pump 10 connects drilling well surface line 11 by pipeline.
Wherein, borehole pump 1 provides pressure source for whole injected system, is particle storage tank 9 pressurising by pressure-equalizing line 2, so that follow-up particle injecting program; Particle charge line 6 is passages of conveying particle, to be particle storage tank interpolation particle, is discharged in overflow tank 8 by overflow line 7 by the drilling fluid in particle storage tank simultaneously; After starting particle injection pump, particle and drilling fluid Homogeneous phase mixing in drilling well surface line, and arrive shaft bottom with drilling fluid, carry out particle impacting break unvenile water pressure valve A hydraulic valve B, hydraulic valve C all automatically controlled by control centre, in system operation, opened and closed by middle control software, realize the operations in particle injection process
When this particle injected system is run, first open hydraulic valve B, in particle storage tank, add particle by particle charge line, open hydraulic valve C, make the drilling fluid in tank be discharged in overflow tank through overflow line, after particle storage tank is full of particle, close hydraulic valve B and hydraulic valve C.Subsequently, open borehole pump, opening hydraulic valve A, make drilling fluid be injected in particle storage tank through pressure-equalizing line, is the pressurising of particle storage tank, is that the pressure in particle storage tank is suitable with the pressure in the outside drilling well surface line be connected of particle injection pump.Now, start particle injection pump, by uniform particle, be injected in drilling fluid stably, arrive shaft bottom by drilling well surface line.
Because situ of drilling well is a continuous print process, in order to prevent due to independent] particle storage tank causes the stagnation of construction, the general alternately operating adopting 2 or 3 particle storage tanks, thus it is continuous to ensure that down-hole particle injects, and improves the efficiency that particle impacting creeps into.Meanwhile, whole process is all controlled automatically by the software of control centre, and each equipment of better start and stop, each valve of switch, realize the Effec-tive Function of particle injected system, meet the demand of onsite application.
