Background technology
In the process of oil well excavation, after oil field enters the tail period oil recovery stage, it is generally adopted artificial to water filling in oil well to keep formation pressure, thus reaching to improve the purpose of ultimate recovery. For obtaining the injection condition information of interval and substratum, the injection profile injecting well measured by the widely used radiosiotope tracer method in oil field. In prior art; it is usually employing isotopic tracer and water to be together injected into inside oil well; but along with water filling; in oil well, hydraulic pressure constantly increases; understand some water outwards to overflow from oil well is internal, containing isotopic tracer in the water of spilling, thus being easily caused the pollution to surface soil; it is unfavorable for the protection of environment, damages to the natural environment after exploitation. Existing injection device improved, directly syringe is proceeded in oil well with water pipe, but above-mentioned using method, need the injection pipeline grown very much, and adopt driving equipment to be injected in oil well by tracer, not only expend the energy, and the uniformity injected is poor, cause the problem that tracer injection is wasted.
Accordingly, because prior art exists above-mentioned technological deficiency, it is those skilled in that art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is for providing the tracer injection device of a kind of improvement, it is intended to the tracer injection device even injection degree solving to exist in prior art is poor, it is easy to wasting problem.
For achieving the above object, this utility model provides following technical scheme:
A kind of tracer injection device of improvement, including injection tube, push liquid sheet, sealing gasket, observation window, spring, syringe, flow controller, inject joint and hold bucket, described injection tube upper end open, described injection tube lower end connects syringe, it is provided with flow controller in the middle part of described syringe, described syringe end is provided with injection joint, described injection joint is connected with water injection pipe, it is provided with push liquid sheet in described injection tube, described push liquid sheet sidewall periphery is provided with sealing gasket, described push liquid sheet lower end is provided with spring, described spring bottom end connects described injection tube inner bottom part, described injection tube sidepiece holds bucket by pipeline connection, described injection tube sidewall is provided with the observation window of glass.
Preferably, also including one-way cock, described one-way cock is located in described syringe.
Preferably, described one-way cock is located between described flow controller and described injection joint.
Preferably, also including fluid filling pump, described fluid filling pump is connected with the described bucket that holds by pipeline.
Of the present utility model have the beneficial effect that by injection tube is transformed and arranged a flow controller, thus convenient, injection volume is controlled accurately, make tracer injection uniform. Its technology path is mainly by the form being set to upper end open at injection tube, and by push liquid sheet and spring with the use of, make tracer in injection tube to hemostasis, controlled the injection rate of tracer by flow controller, and according to waterflood injection rate, the injection rate of tracer can be adjusted; Control tracer by one-way cock and can only be injected into water injection pipe from syringe, it is prevented that tracer is counter chokes, and affects the quality of tracer; Observe injection situation in injection tube by observation window, regulate fluid filling pump to holding bucket pressurization, make tracer inject in injection tube, and by push liquid sheet upwardly, facilitate the injection of tracer. This utility model simple in construction, easy to use, even injection, it is prevented that spill and leakage, good environmental protection.
