Abstract

The invention provides isotopic tracer agent injection equipment. The isotopic tracer agent injection equipment comprises a liquid storage bin, a gas storage tank and an inflator pump, wherein a liquid discharge pipe is arranged at the output end of the liquid storage bin; a piston and a reset spring are arranged inside the liquid storage bin; the reset spring is connected with the inner wall of the liquid storage bin; the liquid storage bin is connected with the gas storage tank through a pipeline with a one-way stop valve; the gas storage tank is also connected with the inflator pump through a pipeline with a one-way stop valve; an injection port is formed in the upper portion of the liquid storage bin; a tracer agent storage tank and a water storage tank are arranged on the two sides of the injection port correspondingly; a one-way stop valve is arranged between the tracer agent storage tank and the injection port; a one-way stop valve is arranged between the water storage tank and the injection port; and the pipeline between the gas storage tank and the inflator pump is detachable. The isotopic tracer agent injection equipment has the beneficial effects of being simple in structure, convenient to use and carry, and capable of being used under the condition of no inflator pump and avoiding pollution of isotopic tracer agents.

Description

[0001] (1) Technical field [0002] The invention relates to an isotope release device, in particular to an isotope tracer injection device. [0003] (2) Background technology [0004] There are many types of isotope release devices, and their action methods are also diverse, including explosive, combustion, and motor-driven, all of which can be quickly opened to release the isotope tracer. After the oil field enters the later stage of development and oil recovery, artificial water injection or polymer is used to maintain the pressure of the oil layer to achieve the purpose of improving the final recovery factor. In order to obtain information on the injection status of intervals and sub-layers, radioisotope tracing methods are widely used in oil fields to measure the injection profile of injection wells. An electric release device is usually used to release the radioisotope tracer at a fixed point. The working principle is that the radioisotope tracer is loaded into the release dev...
