Application of Isotope Tracer in Steamflood Inter-well Tracer Test of the Oil Field

General principle is expatiated for radioisotope tracer applications in steamflood inter well tracer test of the oil field. Frist successful example of field test is described. To get the knowledge of movement of injected steam and accurate the reservoir model of the tested block, triturated water(THO) is used as tracer in the test. Good result of the test is obtained and expected goal is met.
