Description
Technical field
The utility model relates to water injection well in oil fields test isotope and throws in instrument, specifically a kind of drawing-in type underground isotope Solid/liquid two purpose release.
Background technology
The radio isotope release can change former ground injection isotope assay injection profile into down-hole release isotope assay injection profile at present, it can simplify construction technology greatly, shortened the engineering time, eliminated the environment pollution that ground isotope causes, be released into power and also further improve.But because the isotope particle is the easy residual barrel of solid and the impact that is subjected to the well technology for washing well, well-flushing work can't normally be carried out, especially adopt carrying out of work along with three, polymer injection well increases gradually, the dirty phenomenon of the fouling of tubing and casing tubing string, tube wall is more and more serious, cause the isotope particle more and more serious at the pickup at tube wall and instrument place, directly affected the accuracy rate of the explanation of injection profile data, brought certain difficulty for lower step process measure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of drawing-in type underground isotope Solid/liquid two purpose release is provided.
Technical solutions of the utility model comprise: top connection, rotary sleeve, quiet piston, upper shell, moving piston, transition joint, sealing ring, lower house, lower contact, power supply top connection, hollow shaft, reducer, motor, wiring board, power supply lower contact.Its drawing-in type underground isotope Solid/liquid two purpose release is cylindrical structure, and top connection from top to bottom, upper shell, transition joint, lower house are threaded successively, between be equipped with the two seals circle; The top connection center is provided with the power supply top connection, upper shell top is provided with rotary sleeve, the quiet piston of the relative hollow cone bodily form, moving piston are equipped with in inside, form bicone isotope feed bin, moving piston and hollow shaft thread connection, hollow shaft is passed transition joint and is connected with multistage planet reducer, high temperature dc motor, is provided with equally the two seals circle between hollow shaft and the transition joint, is provided with wiring board between motor and the power supply lower contact.
