Support jar in the such scheme is outside equipped with the rock wool heat-preservation layer.
The present invention has following beneficial effect: supporting jar built-in buoyant tank that can fluctuate owing to adopt, support jar inner seal ring and buoyant tank branch and be separated with injection chamber and hydraulic chamber, support a jar medicine outlet that upward is connected and pass through pipeline successively with the injection chamber, proportional valve, switch valve, flap valve and stop valve are connected with the surface casing pressure valve, supporting a jar dosing mouth that upward is connected with the injection chamber is connected with dosing pump by pipeline and valve, support and jar to go up the structure that the water inlet that is connected with hydraulic chamber comes water pipe to be connected by pipeline and stop valve and the water mixing of well head, utilize water mixing to come 60 degree heat hydraulic pressures of water pipe to promote buoyant tank, inject into well by the indoor soup of buoyant tank extruding injection again, so promptly solved dosing dynamical problem and dosing insulation problem, and be airtight operation, not only save the energy but also reached the purpose of safety and environmental protection.This self-operated drop instillator has the power of need not, attemperator and electric heater unit thus, the characteristics that security reliability is good He free from environmental pollution.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
1-supports jar, 2-buoyant tank, 3-sealing ring, 4-injection chamber, 5-hydraulic chamber, 6-valve among the figure, the 7-proportional valve, the 8-switch valve, the 9-flap valve, the 10-stop valve, 11-casing pressure valve, the 12-water mixing comes water pipe, the 13-dilution valves, 14-isolating valve,, 15-high-pressure hose, 16-balance pipe, 17-balance pipe, 18-emptying valve.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, this self-operated drop instillator comprises support jar 1, support jar 1 and be built-in with the buoyant tank 2 that can fluctuate, on supporting in the jar 1, the bottom is fixed with and buoyant tank 2 contacted sealing rings 3, support jar 1 and be separated with injection chamber 4 and hydraulic chamber 5 in 2 minutes by sealing ring 3 and buoyant tank, support on the jar 1 medicine outlet that is connected with injection chamber 4 is arranged respectively, dosing mouth and the water inlet that is connected with hydraulic chamber 5, the dosing mouth of injection chamber 4 is connected with dosing pump by pipeline and valve 6, the medicine outlet of injection chamber 4 passes through pipeline successively, proportional valve 7, switch valve 8, flap valve 9 and stop valve 10 are connected with surface casing pressure valve 11, the water inlet of hydraulic chamber 5 comes water pipe 12 to be connected by pipeline and stop valve 10 with the water mixing of well head, pass through pipeline at switch valve 8 and 9 on flap valve, dilution valves 13, stop valve 10 and isolating valve, 14 come water pipe 12 to be connected with the well head water mixing, 10 of dilution valves 13 and stop valves are connected with balance pipe 16 in the buoyant tank 2 by high-pressure hose 15, there is balance pipe 17 buoyant tank 2 lower ends, support jar and be connected with emptying valve 18 1 time, support jar 1 and be outside equipped with the rock wool heat-preservation layer.
During actual the use, dosing or tonic operating process are communicated with by pipeline and valve 6 dosing pump with the dosing mouth of injection chamber 4, open stop valve 10 on the medicine outlet of valve 6 and injection chamber 4, close flap valve 9, the pressure of dosing pump makes buoyant tank 2 descending greater than original annotation coyote hole 4 internal pressures, to directly under the pressure effect of dosing pump, buoyant tank 2 goes downwards to and supports at jar 1 end, medicine is filled it up with back shut off valve 6, and dismounting is dosing pump down, and dosing or tonic operation are finished.Open stop valve 10 on the medicine outlet of flap valve 9 and injection chamber 4, begin normal injection.
The injection process, shut off valve 6, isolating valve, 14 and emptying valve 18, open proportional valve 7, switch valve 8, flap valve 9, stop valve 10, dilution valves 13, stop valve 10 on 9 pipelines of switch valve 8 and flap valve, casing pressure valve 11 on stop valve 10 and the well head on the water inlet pipeline of hydraulic chamber 5, come 60 degree hot water of the 1.5-1.8 MPa pressure of water pipe 12 to enter hydraulic chamber 5 by water mixing, it is up to promote buoyant tank 2, injection chamber 4 smaller volume, soup is forced out, through proportional valve 7 and switch valve 8, with by the balance pipe under the buoyant tank 2 17, balance pipe 16, high-pressure hose 15, the hot water of dilution valves 13 and medicine dilution, form medicine liquid mixture, medicine liquid mixture is again through flap valve 9, stop valve 10 and casing pressure valve 11 enter well head, fall into the interior bottom of sleeve pipe by the medicine liquid mixture self gravitation, finish continuous injection process.
This self-operated drop instillator mainly adopts and supports the buoyant tank 2 that setting can fluctuate in jar 1, utilizes 60 degree hot water of 1.5-1.8 MPa pressure that water mixing comes water pipe 12 as power and thermal source, realizes that need not power is incubated airtight safety and environmental protection service requirement.And it is few to have an investment goods, and fault rate is little, saves the maintenance cost characteristics.And can need design big capacity injection chamber 4 by the user, prolong the tonic cycle.
