Description
Technical field
The utility model belongs to oil extraction in oil field engineering field, relates to a kind of oilfield chemical dosing instrument, specifically balances pusher environmental protection doser.
Background technology
When oil well is to the dosing cycle, generally adopt two kinds of dosing methods:
One is by oil sets annular space gas from the emptying of sleeve pipe atmospheric valve, ensures to be in passive state in pit shaft oil jacket annular space, then dosing funnel is inserted ferrule boot and adds in well by liquid; This dosing method exists because natural gas arranges the waste causing the energy outward, simultaneously large to atmosphere pollution, and during dosing, well head may have flammable oil, gas at any time in addition, easily has an accident, dangerous high;
But the pressurization of high pressure pump truck, when pressure exceedes formation pressure, liquid injects pit shaft, thus realizes molten wax, the effect of paraffin removal, reduces crude oil flow resistance in the wellbore, improves pump detection period; But during its high pressure pump truck pressurization dosing construction, the internal pressures such as pressurized equipment, well head connecting portion are all at more than 5Mpa, namely under high pressure run, there is certain potential safety hazard, and require that staff is in the safety zone apart from job site certain distance, make troubles to operation in work, the liquid having some in addition in connecting line cannot reclaim, and also causes certain waste.
Summary of the invention
In order to large, the dangerous high and unhandy problem of the wasting of resources, the pollution that solve prior art existence, the utility model proposes simple, easy to operate, the dangerous low and practical doser of a kind of structure, its concrete technical scheme is as follows:
Balance pusher environmental protection doser, comprise the hoop be connected with wellhead casing pipe valve, described hoop is connected with outer tube, outer tube is tightly connected by hoop and wellhead casing pipe, described outer tube inside is provided with inner sleeve, and inner sleeve one end is in inside wellhead casing pipe through hoop, and the inner sleeve other end contacts with the baffle plate being in outer tube inside, be connected with augering screw one end in the middle part of baffle plate, the augering screw other end is in outside one end that outer tube is not connected with wellhead casing pipe; Upper end, outer tube stage casing is connected with the lower end conducting of dosing outlet, dosing outlet stage casing is connected with dosing outlet valve, dosing outlet upper end is connected with tank body conducting, tank body front end face is provided with the looking glass longitudinally arranged, tank body upper center is connected with the lower end conducting of dosing inlet tube, dosing inlet tube stage casing is connected with dosing inlet valve, and dosing inlet valve upper end is connected with funnel conducting.
Described tank body upper end is connected with the conducting of balance pipe one end, and the balance pipe other end is connected near the conducting of hoop place with outer tube.
Described baffle plate lower end has gap.
Described outer tube is provided with pressure meter.
The beneficial effects of the utility model: medicament is annotated in well by quick, intuitive and accurate mode, effectively realize the effect of pit shaft wax removal, guarantee that oil well is normally produced, oil well can be realized work under artesian condition, change funnel dosing method in the past i.e. dangerous but also adding method thereof not environmentally, the manpower and financial resources loss of high pressure pump truck dosing method can be reduced again simultaneously, the dead oil accumulated in four-way can be removed in addition; Structure is simple, operation and easy to use and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-hoop, 2-outer tube, 3-inner sleeve, 4-baffle plate, 5-augering screw, 6-dosing outlet, 7-dosing outlet valve, 8-tank body, 9-looking glass, 10-dosing inlet tube, 11-dosing inlet valve, 12-funnel.
Detailed description of the invention
For the ease of understanding, below in conjunction with Fig. 1, the utility model is further illustrated:
Embodiment 1: balance pusher environmental protection doser, comprises the hoop 1 be connected with wellhead casing pipe valve, for fixing and sealing; Described hoop 1 is connected with outer tube 2, and outer tube 2 is tightly connected by hoop 1 and wellhead casing pipe, and described outer tube 2 inside is provided with inner sleeve 3, and inner sleeve 3 one end is in inside wellhead casing pipe through hoop 1, and inner sleeve 3 is for dredging medicament; Inner sleeve 3 other end contacts with the baffle plate 4 being in outer tube 2 inside, is connected in the middle part of baffle plate 4 with augering screw 5 one end, and augering screw 5 other end is in outside one end that outer tube 2 is not connected with wellhead casing pipe; Upper end, outer tube 2 stage casing is connected with dosing outlet 6 lower end conducting, dosing outlet 6 stage casing is connected with dosing outlet valve 7, dosing outlet 6 upper end is connected with tank body 8 conducting, tank body 8 front end face is provided with the looking glass 9 longitudinally arranged, tank body 8 upper center is connected with dosing inlet tube 10 lower end conducting, dosing inlet tube 10 stage casing is connected with dosing inlet valve 11, and dosing inlet valve 11 upper end is connected with funnel 12 conducting;
Operating process is as follows:
After this product is connected with wellhead casing pipe valve, liquid is added in tank body 8 by funnel 12, close dosing inlet valve 11, open dosing outlet valve 7, inner sleeve 3 is pushed in pit shaft by adjustment augering screw 5, observe tank body 8 level window liquid level by looking glass 9 and move down situation, to treat in tank body 8 that the whole stream of liquid to cause in pit shaft with aforesaid way again to dosing in pipe, until after individual well chemical feeding quantity meets the demands, augering screw is retracted, removes chemicals dosing plant.
