The beneficial effects of the utility model are that: according to the different and nimble adjustment construction quantity of the on -the -spot condition of hole condition, realize gaseous spike agent scene and fill, pour into into, avoid the repeated dismouting work of equipment, can be under construction in succession, shorten the engineering time, improve gaseous spike agent utilization ratio simultaneously, realization high -tension apparatus is automatic closes down, the automatic pressure release that transfinites, and the security performance is high, but wide application in the gaseous spike agent injection work of gas drive well.
Description
Technical field
The utility model relates to a kind of gas tracer filling device, belongs to oil and gas well testing technical field.
Background technology
Oil-gas mining has developed multiple gas drive technology to the middle and later periods, comprises natural gas drive, carbon dioxide flooding, nitrogen foam drive, steam flooding etc.Gas drive carries out scope extensively, injects capital into high, needs gas tracer method between well to provide corresponding data in measure formulation and effect assessment.Because the parameters such as gas drive well group well spacing, core intersection, degree of porosity, permeability and background concn are different, each well is also different to the demand of gas tracer, need one can adjust on-the-spot injection rate flexibly, can the injection device of sequential production, simultaneously, the usual pressure of gas drive well is higher, needs equipment to provide safety assurance.ZL200420064609.7 discloses a kind of gas tracer filling device, be made up of fuel tank, switch board, motor, oil pump, stop valve, pressure meter, switching valve, bellows compression cylinder bottle, needle-valve, one way valve, chassis, its gas tracer is contained in bellows compression cylinder bottle in advance, in-site installation is on injection device, when gas tracer design quantity is greater than the prepackage total amount in bellows compression cylinder bottle, dismounting need be carried out to injection device, gas tracer is loaded in bottle, reinstall bellows compression cylinder bottle again, therefore operate comparatively loaded down with trivial details and have potential safety hazard to exist.
Utility model content
The utility model object is that the bellows compression cylinder bottle tolerance deficiency solving the existence of existing gas tracer filling device needs repeated removal filling, causes there is the problems such as potential safety hazard, provides a kind of gas tracer filling device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gas tracer filling device, be made up of stock bottle, inflator pump, displacement pump, fuel reserve tank and compression cylinder barrel, inflator pump, stock bottle and well head are sequentially connected in series by pipeline, be connected in parallel to two or more between the pipeline of stock bottle and well head and fuel tank and compress cylinder barrel, fuel tank is connected with displacement pump by pipeline.
The beneficial effects of the utility model are: adjust construction consumption flexibly according to hole condition difference and field condition, realize gas tracer in-site pouring, injection, avoid the repetition disassemble and assemble work of equipment, can sequential production, shorten the engineering time, improve gas tracer utilization rate simultaneously; Realize high-tension apparatus automatically to close down, transfinite releasing pressure automatically, and security performance is high, can be widely used in the gas tracer injection work of gas drive well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of gas tracer filling device, be made up of stock bottle 1, inflator pump 2, displacement pump 3, fuel reserve tank 5 and compression cylinder barrel 6, inflator pump 2, stock bottle 1 and well head 9 are sequentially connected in series by injection manifold, between injection manifold and the fuel-displaced manifold of fuel reserve tank 5, be parallel with two or more compress cylinder barrel 6, fuel reserve tank 5 is connected with displacement pump 3 by oiling pipeline.
Injection manifold between described stock bottle 1 and well head 9 is provided with safety valve 8.
The fuel-displaced manifold of described fuel reserve tank 5 is provided with electro connecting pressure gauge 4.
The import and export two ends of described compression cylinder barrel 6 are separately installed with valve.
The preparation of injection device: after switching on power, arranges the restriction pressure of safety valve 8 and electro connecting pressure gauge 4.
Gas tracer filling: the import and export two ends valve opening compression cylinder barrel 6, close the valve of well head 9, start inflator pump 2, open the outlet valve of stock bottle 1, gas tracer in stock bottle 1 is pumped in compression cylinder barrel 6, the piston 7 promoted in compression cylinder barrel 6 comes downwards to bottom compression cylinder barrel 6, closes the outlet valve of stock bottle 1.
The injection of gas tracer: the valve opening well head 9, start displacement pump 3, the hydraulic oil pump of fuel reserve tank 5 is delivered in compression cylinder barrel 6, the piston 7 promoted in compression cylinder barrel 6 is up, gas tracer in compression cylinder barrel 6 is pumped in well head 9, when compressing the piston 7 in cylinder barrel 6 and going upward to the top of compression cylinder barrel 6, due to rigidity extruding, pump pressure rapidly increases to the restriction pressure of electro connecting pressure gauge 4, displacement pump 3 termination of pumping, thus complete the injection of gas tracer, if the gas tracer capacity in compression cylinder barrel 6 does not reach design injection rate, repeat above-mentioned filling and implantation step, can the many wells of sequential production.
In gas injection work, if well head 9 pressure anomaly causes the pressure in pipeline to exceed the restriction pressure of safety valve 8, safety valve 8 opens below pressure release to limiting pressure automatically, ensure that the safety of construction.
