In the mathematical model of conventional three-dimensional two-phase non-distributive and distributive tracers problems,the concentration of water component in water phase Cww and the concentration of oil component in oil phase Coo are unknown in the water and the oil component functions,which would cause massive calculations to solve difference equations in the basic model.

The results of experimentally screening interwell tracers for use in a trial area of southern district Ⅱ of Daqing are presented.

The driving pilot test of surface active agent is implemented at the layers V2-5 in the area B125 of Gucheng Oilfields, in which the purposes of injecting tracers are to understand the connection states between injection- production wells, the direction and speed of plane water flowing, and the states of heterogeneity in oil reservoir.

In order to reduce the well interference and raise the oil reservoir producing degree,water injection tracing agent technique was utilized in Z2 fault block monitoring,to further understand the displacing direction,velocity,and sweep range of the injected water,as well as the conditions of substratum communication and flooded horizons.

The karst groundwater linkage test is conducted for the Dawu water source station of Qilu General Petrochemical Company, utilizing the artificial radioactive isotope I as a tracing agent, the effect is satisfactory .

As a tracing agent, the radioactive isotope has a high sensitivity for detection.
