Abstract
The invention relates to a device for releasing underground radioactive tracer; the releasing device comprises an instrument wall, a movable radioactive tracer chamber is located in the instrument wall and a diluting and mixing chamber; the middle part of the instrument wall is provided with a tracer releasing opening; the radioactive tracer chamber is located above the tracer releasing opening; the diluting and mixing chamber is located under the tracer releasing opening; the radioactive tracer chamber is sealed, the lower part thereof is provided with a nozzle, the upper part is provided with a transmission shaft; the upper part of the diluting and mixing chamber is opened, the opening part is provided with a sealing ring; a stirring device is disposed in the diluting and mixing chamber. The invention also relates to a new method for releasing underground radioactive tracer; the basic point of the method to uniformly mix the tracer with the well liquid in the mixing chamber, so as to form slug; then the tracer is directly released to the well by the way of tracer slug. The invention fundamentally solves the problem of the traditional tracer injecting method that the tracer cannot be uniformly mixed to form the slug, so as to avoid the risk in the traditional construction that the instrument can be damaged or drop underground because of pulling and shaking.
Description
Technical field
The present invention relates to oil, natural gas extraction field, specifically a kind of method and device thereof of the novel measurement Injection Well tracer for down-hole.
Background technology
It is generally that ejector is positioned on the sidewall of instrument cylinder that traditional downhole radioactive tracer discharges.In laminar flow, after tracer is ejected, be originally to drip along instrument outer wall, and then clash into casing wall.
Research shows, the down-hole release conditions of radioactive tracer is very large on logging quality impact, researcher finds, under the traditional injection apparatus of above-mentioned tradition, jet velocity, injecting time, jet size and fluid velocity are all the factors that affects tracer release quality.So, adopt traditional injection apparatus must control the factor of these aspects well and could effectively improve the quality of tracer flow rate log.
Radioactive tracer log technology generally has two methods: tracer tachometric method and tracer loss method.
(1) well logging of tracer tachometric method must form good tracer slug after tracer sprays, can measure obvious tracer slug peak value to guarantee instrument, and be limited by the combined factors impacts such as jet velocity, injecting time, jet size and fluid velocity, be often difficult to ensure to reach construction requirement;
(2) tracer loss method well logging needs to guarantee that tracer mixes in liquid in well.Tracer slug in order to obtain mixing in tracer loss well logging, generally taking now to move up and down rapidly instrument after tracer sprays makes it by tracer slug, so that the method that tracer mixes with fluid well-distributing, the clashing and breaking that this method has increased again instrument and the borehole wall are the risk under back drop even.
Summary of the invention
The present invention is directed to use that traditional radioactivity release method and device thereof exist because the complicated factors such as jet velocity, injecting time, jet size and fluid velocity cause tracer in the adhesion of apparatus wall and casing wall and adhere to and can not be uniformly mixed to form the problem of slug, designed a kind of novel downhole radioactive tracer method for releasing and device thereof.
Technical scheme of the present invention is as follows:
A kind of releasing device of downhole radioactive tracer, described releasing device comprises instrument tube wall, be positioned at movably radioactive tracer storehouse and dilution mixing bunker of instrumentation tube pars intramuralis, the middle part of instrument tube wall is provided with tracer liberation port, radioactive tracer position in storehouse is in the top of tracer liberation port, and dilution mixing bunker is positioned at the below of tracer liberation port; Radioactive tracer storehouse is sealing, and bottom is provided with nozzle top and is provided with power transmission shaft, dilution mixing bunker upper opening, and peristome is provided with sealing ring, and the inside of dilution mixing bunker is provided with mixing plant.
Preferably, described mixing plant comprises eyelet agitating plate and the power transmission shaft being connected with eyelet agitating plate, and power transmission shaft stretches out from the bottom of dilution mixing bunker.
Preferably, described inside, radioactive tracer storehouse is provided with piston.
Preferably, the nozzle in radioactive tracer storehouse is provided with electromagnetic valve.
Preferably, on the inwall of instrument tube wall, be provided with limited block.
A kind of Novel down-hole radioactive tracer method for releasing, comprises the following steps:
A. dilute on mixing bunker and push away, withstand on bottom, radioactive tracer storehouse, edge seals with sealing ring;
B. radioactive tracer storehouse sprays into radioactive tracer by nozzle in dilution mixing bunker;
C. eyelet agitating plate moves up and down and rotates in dilution mixing bunker, is uniformly mixed radioactive tracer;
D. eyelet agitating plate playback forms radioactive tracer slug in dilution mixing bunker;
E. transfer dilution mixing bunker and start to discharge radioactive tracer slug;
F. transfer in radioactive tracer storehouse, by radioactive tracer slug, by the tracer liberation port of instrument tube wall, releases radioactive tracer slug in well.
The present invention fundamentally solved in traditional tracer injection method, may occur because the complicated factors such as jet velocity, injecting time, jet size and fluid velocity cause tracer in the adhesion of apparatus wall and casing wall and adhere to and can not be uniformly mixed to form the problem of slug, evaded the risk under instrument clashing and breaking and the back drop that needs in traditional construction to lift up and down, shakes and bring.
