Problems solved by technology

The existing injection process system is prone to leakage under high pressure, and the operation process is open when the isotope is injected in the field operation, which often causes environmental pollution and threatens the health of operators
After the injection is completed, it must be disassembled, cleaned, and reloaded with a new isotope carrier for another injection, which is labor-intensive and time-consuming and will increase pollution

Abstract

The invention discloses an isotope tracer injector, and relates to the isotopic tracing field. The isotope tracer injector specifically comprises a box body with an opening in the upper end, a seal plug connected onto the opening of the box body, and a water inlet and a water outlet which are formed in the box body, wherein a cavity of the box body and the seal plug form a mixing chamber, a vertical screen drum is arranged at the bottom of the mixing chamber, a bottom plate is arranged at the bottom of the screen drum, and a press plate is arranged in the screen drum. The isotope tracer injector further comprises a first drive device which drives the screen drum to rise and fall, and a second drive device which drives the press plate to rotate. A storage pipe used to store isotope carriers is arranged on the inner circular face of the screen drum, and is arranged along the axial direction of the screen drum, and located above the press plate. A collision prevention groove corresponding to the storage pipe is formed in the press plate. The isotope tracer injector can achieve repeated injections, and can not pollute the outer world due to the fact that the isotope tracer injector is tightly sealed during the injection process.

Description

【Technical field】 [0001] The invention relates to a syringe, in particular to an isotope tracer injector. 【Background technique】 [0002] In the research and development of the isotope tracer cross-well monitoring project, an important link is to inject the isotope tracer into the wellbore safely and smoothly. The existing injection process system is prone to leakage under high pressure, and the operation process is open when the isotope is injected in the field operation, which often causes environmental pollution and threatens the health of operators. After the injection is completed, it must be disassembled, cleaned, and reloaded with a new isotope carrier for another injection, which is labor-intensive and time-consuming and will increase pollution. 【Content of invention】 [0003] The technical problem solved by the invention is to provide an isotope tracer injector, which has good sealing performance and can realize continuous multiple injections. [0004] In order ...
