Abstract
Down-hole localized releasing apparatus for isotope carrier is a kind of field produces well radioisotope logging downhole tool, and it utilizes level pressure diaphragm breakdown principle under the certain pressure effect, and the inlet opening and the release aperture of coming control instrument make isotope discharge in the down-hole desired depth.It is a kind of can directly be connected with radioactivity logging device or connect with steel wire for logging go into the well separately, also need and microsphere supported matching used isotopic carrier down-hole release.This instrument has improved the test success rate effectively, has eliminated radioactive pollution, also can carry out normal radioisotope logging to well head gate severe leakage and the bigger water injection well of well head spillway discharge.
Description
Down-hole localized releasing apparatus for isotope carrier belongs to a kind of field produces well radioisotope logging downhole tool.
Consulted United States Patent (USP) in this instrument research process in No. 3248540 " logging method of radioactive tracer and instrument "; No. 3317726 documents such as " differentiating the radioactive logging technology at water logging of stratum position in the oil well " of United States Patent (USP).The present invention in the past both at home and abroad radioisotope logging all adopt by aboveground and isotopic carrier poured into " pouring method into " construction of logging well in the well, this job practices causes the radioactive pollution of well site, wellhead equipment and water injection string in the well logging process, endanger personal safety simultaneously, especially serious for the leakage of well head gate, the water injection well that the well head spillway discharge is bigger, " pouring method into " construction can't be utilized, radioisotope logging can not be carried out.
The object of the present invention is to provide a kind of new radioisotope logging downhole tool, it can overcome the above-mentioned shortcoming that " pouring method into " exists, and has the requirement according to well logging, in corresponding down well placement, discharges the technical performance of isotopic carrier.
Fig. 1 is the structural representation of down-hole localized releasing apparatus for isotope carrier.The structure of release can be divided into and connecting and release two parts.Coupling part: be positioned at the top of instrument, form by special joint (1), connection pin (2), top connection (3); Release portion: form by diaphragm (4), sleeve (5), sliding sleeve (6), connector (7), carrier tube (8), valve seat (9), following valve (10), piston cylinder (11), spring (12), sealed packing (13).Sleeve (5) upper and lower side joins with top connection (3) and connector (7) respectively, carrier tube (8) upper and lower side is connected with valve seat (9) with connector (7) respectively, piston cylinder (11) is connected on the below of valve seat (9), and spring (12) is contained in the piston cylinder (11).
Fig. 2 is the tube-in-tube structure schematic diagram, and having four uniform grooves on the sleeve (5) is inlet opening (14), has two screw holes (15) on the other direction of groove.Sliding sleeve (6) is contained in sleeve (5) interior normal pressure lower seal inlet opening (14).
Fig. 3 is the valve seat structural representation.Having four uniform grooves on the valve seat (9) is release aperture (16), and the spring (12) of following valve (10) in normal pressure lower seal release aperture (16) piston cylinder (11) withstands valve (10) down.
Diaphragm (4) is positioned at the top of sliding sleeve (6).
Release can connect with being connected pin (2) with the logging instrument bottom fitting, also can with logging instrument bottom by special joint (1) use that is threaded, can also be with the steel wire for logging connection use of going into the well separately if is not connected with logging instrument, this instrument should with microsphere supported supporting use.
The operating principle of release is to utilize metallic membrane breakdown under the certain pressure effect, highly pressurised liquid acts on the stressed end face of sliding sleeve (6) by the position that breaks, sliding sleeve (6) is pushed and moves down, open the inlet opening (14) on top, Jing Neigaoyashui is full of the carrier tube (8) of instrument rapidly, act on down simultaneously on the end face of valve (10), open carrier release aperture (16), carrier evenly enters in the well under the drive of injecting current, on release, mention well head, pressure in the carrier tube (8) descends, and following valve (10) is closed release aperture moving on voluntarily under the effect of spring (12).
It is that diaphragm can use metal to make by the material of diaphragm (4) and thickness decision that this instrument discharges depth location, and the most handy fragile material CY-CZ11A cast aluminium alloy is made, and working pressure is 980.67 * 10
4More than the Pascal, can make instrument be controlled at any position release below the well head by diaphragm thickness.
In order to prevent that sliding sleeve (6) from moving down in advance, it is spacing to add the M2 brass screw on sliding sleeve.
Down-hole localized releasing apparatus for isotope carrier has the following advantages:
1. this release scene is safe and reliable, the success rate height.
2. to well head gate severe leakage, the water injection well that the very big usefulness of spillway discharge " is poured method into " and can not be constructed is constructed with the test that the down-hole release can carry out normal water filling fully.
3. the down-hole release has been eliminated the radioactive pollution of well site, wellhead equipment, oil reservoir above tubing string, helps environmental protection.
4. can be according to logging requirements, any degree of depth in the down-hole discharges isotopic carrier.
5. the radioactive pollution that discharges instrument valve surface, back is slight, and instrument can be reused after cleaning.
6. simple in structure, assembling, maintenance, connect and use all very convenient.
Down-hole localized releasing apparatus for isotope carrier is a kind of novel isotope down-hole releasing tool; this invention has improved the success rate of isotope injection profile test greatly; eliminated radioactive pollution effectively; the production and injection proration scheme is formulated in the oil field; proposition is taped the latent power, the adjusting process measure; decreasing water cut and increasing oil continues stable yields considerable economic, aspect environmental protection and operating personnel's the personal safety good social benefit is being arranged.
