The method solves the problems of great environmental pollution, long nuclide half-life periods, the toxicity of the carriers, high desorption rate, sinking, missing, etc. Accordingly, the present invention is an ideal radioactive tracer logging method of isotopes.
Description
The invention belongs to a kind of survey of wells by radioactive isotope tracking method, particularly use
113mIn makes tracer nuclide and combines the method for measuring gas well, oil well or water injection well with carrier.
The application of radiation isotope tracer technique has the history of decades in the oil-field development well logging; once used radioactive tracer nucleic has tens kinds in well logging, but all brings difficulty for environmental protection, repeat logging, apparatus guarantee because of the half life period of these nucleic is long.The nucleic that has is desorption from the carrier easily, the then existence contamination that has, sinking, problem such as missing.Used afterwards that indium-113m generator produces
113mThe eluent of In nucleic is as the spike carrier, and the release of packing into is released in the measuring well, directly is used for surveying the flow of producing well, obtains measurement result by logging instrumentation.But its density is greater than 1g/cm
3(oil density is generally 0.86g/cm
3) differ bigger with production fluid density, and can not flow synchronously, cause dynamic measurement error and can not use.Utilize
113mIn combines the method that is used to measure gas well, oil well or water injection well as the spike carrier and does not appear in the newspapers with carrier.
The object of the present invention is to provide a kind of tracer nuclide half life period short, spike carrier proportion and production fluid or injection water are near, and The result of dynamic test is measured the survey of wells by radioactive isotope tracking method of gas well, oil well or water injection well accurately.
The present invention selects for use and is produced by indium-113m generator
113mIn is a tracer nuclide.
113mThe parent of In is
113mSn,
113mThe half life period of Sn is 115 days, and therefore, the generator of one 50 millicurie can use 1 year, and generator is installed on the open-air logging operation car, on-the-spot generation, ready access upon use.
113mIn uclear purity height (greater than 99.9%), radioimpurity radioactive impurity is few, avirulence, and the half life period all lack than half life period of any radioactive nuclide of used well logging usefulness once, have only 99.5 minutes, therefore, it, just can eliminate the pollution of logging instrumentation and environment measuring well in one day.What produce by indium-113m generator
113mThe In eluent is attached to the spike carrier of constructing as gas well, oil well or water injection well radioactive isotope on gas, solid or the liquid-carrier, measure the aerogenesis flow of gas well, the production fluid flow of producing well, it is logical etc. that the intake profile of water injection well, fracturing effect, the oil-water-layer of perhaps checking oil reservoir are scurried.
113mThe eluent of In nucleic combine with gas, solid or liquid-carrier make the spike carrier be used for the well logging, environmental pollution is little, solid carrier is to the high adsorption capacity of radioactive nuclide, desorption not with variation of temperature, in the scope of room temperature to 100 ℃, adsorption rate is greater than 90%, desorption rate is less than 5%, avirulence do not have to be stain, and problem such as does not have and missing.
Method of the present invention is: the hydrochloric acid drip washing indium-113m generator with 0.05mol/l obtains
113mThe In eluent, with its extraction in the volatile organic solvent of low boiling (as ether) as the tracer gas technique carrier, be released in the gas well with the atomizing release, measure aerogenesis flow, the gas entry profiling of gas well, the leakages of gas tank, tracheae etc. obtain measurement result by logging instrumentation.
Hydrochloric acid drip washing indium-113m generator with 0.05mol/l obtains
113mThe In eluent is adsorbed on it solid carrier (as ion exchange resin microballoon, activated carbon microballon or activated carbon granule) then and goes up as solid spike carrier, and its density is 1.00～1.06,1.05～1.10,1.10～1.25, granularity is 30 μ m～100 μ m, 100 μ m～300 μ m, 300 μ m～500 μ m, 500 μ m～700 μ m etc., desorption rate＜5%, these spike carriers are packed into to be discharged in the down-hole in the release, measure profile-log of water injection, obtain measurement result by logging instrumentation.
Hydrochloric acid drip washing indium-113m generator with 0.05mol/l obtains
113mThe In eluent, with its extraction or sneak into be dissolved in that oil does not dissolve in water or the water-soluble liquid-carrier (as n-propanol, kerosene etc.) that is insoluble to oil in, as liquid spike carrier, its density and production fluid or injection water are almost equal, error is not more than ± 0.02g/cm
3, thereby can flow synchronously with production fluid or injection water.Liquid spike carrier is released in the well, measures the production fluid flow of oil well or the injection discharge of water injection well, obtain The result of dynamic test by logging instrumentation.
In sum, the present invention is achieved in that a kind of survey of wells by radioactive isotope tracking method, and it comprises with hydrochloric acid drip washing indium-113m generator, obtains
113mThe In eluent is made the spike carrier, and the release of packing into is released in the measuring well, obtains test result by logging instrumentation, wherein said spike carrier be with
113mThe In eluent is attached to making on gas, solid or the liquid-carrier.
113mThe carrier gas that the In eluent adheres to is the volatile organic solvent ether of low boiling; Accompanying solid carrier and ion exchange resin microballoon, activated carbon microballon or activated carbon granule; Accompanying liquid-carrier is liquid organic reagent.
The present invention has following good effect:
Adopt
113mIn makes tracer nuclide and combines with carrier and make the spike carrier, the method that is used to log well, radionuclide halflife is short, avirulence, environmental pollution is little, has solved other nucleic desorption from the carrier, produces slippage, missing, sink, on problem such as scurry.And spike carrier proportion and production fluid or to inject water near, The result of dynamic test is accurate.This method is a kind of desirable radioisotope log method.
