Background
The radioactive isotope tracer used for injecting profile logging by radioactive isotope tracer method is solid spherical particle, and its logging principle is as follows: the radioactive isotope solid tracer is injected into water from the releaser, moves along with the water, when the radioactive isotope solid tracer reaches the water-absorbing layer, the injected water enters the stratum, the tracer is remained on the surface of the water-absorbing layer, the gamma ray intensity emitted by the tracer is detected by an instrument, and the injection section condition can be obtained through calculation. It is generally believed that the radioisotope tracer is selected to have a density that is the same as or greater than the injected water when the radioisotope reaches the absorbent layer from above the absorbent layer, and to have a density that is the same as or less than the injected water when the radioisotope reaches the absorbent layer from below the absorbent layer in an upward-return manner. The degree of mineralization of the injected water also affects the selection of the tracer, wherein the tracer with a higher degree of mineralization is selected to have a higher density, and the tracer with a lower density is selected to have a lower density.
The radioactive isotope tracer used for injecting profile well logging by isotope tracer method is generally prepared by the method disclosed in Chinese patent CN201110057628.1, the carrier loaded with isotope at early stage is generally silica gel or active carbon, the two carriers have strong isotope adsorption capacity but higher density, the density of the prepared tracer is also higher, the tracer is suitable for injecting well, when logging and returning well, the tracer is required to rise to water-absorbing layer along with water, some difficulties may occur, and at this time, the density is required to be equal to or slightly lower than that of the carrier injected water. The method for the density-controllable carrier disclosed in the prior art realizes the controllable adjustment of the carrier density, so that the adjustment of the density of the radioactive isotope tracer is free from the condition of relying on a single mode of surface modification, and the density adjustment range is wider. The radioactive isotope tracer which meets different logging conditions and meets market requirements can be obtained by utilizing the prior art. With the enhancement of the awareness of society to environmental protection, some experts in the industry believe that the tracer will affect and even block the pores of the water injection layer rock stratum, and the risk can be avoided by adopting the radioactive isotope tracer which can be degraded in the water injection environment. The previous patent contains technologies such as density adjustment, isotope loading, surface modification and the like, is relatively perfect in the aspect of solid-state radioisotope tracers and is relatively effective from the perspective of popularization and application, but few attention is paid to the degradable property of the radioisotope tracers, and a plurality of logging units have generated the requirements on the degradable radioisotope tracers.
