Radioisotope Tracing Technology for Hydraulic Fracturing of Low-Permeability Shale Oil
摘要
This article uses advanced Monte Carlo simulation and other computational techniques to establish a simulation calculation model for downhole tracer sand testing. By calculating the following parameters, it guides on-site fracturing tracer experiments and data evaluation and interpretation. Calculate the effective depth, dosage, and minimum concentration of three different energy level tracers Scanium-46, Antimony-124, and Iridium-192 in fracturing fractures. Based on the geological model of the given underground tracer sand test, under different geological formations, crack widths, and spatial distribution of indicator sand, the corresponding detector energy spectrum response is obtained through simulation calculation. Based on the response of the detector, the parameters such as near wellbore concentration and equivalent depth of each tracer can be preliminary determined. Through computer simulation, study the techniques and interpretation methods for evaluating hydraulic fracturing effects using tracer sand testing.
