At present, the interpretation method for interwell tracer test not considering the geologic model was called landmark. The interpretation methods for interwell tracer test considering the geologic model have three kinds: analytic method, numerical simulation method, semi-analytic method. But the two formers both have great limitations. When well pattern is a little more complex, analytical expressions can’t be obtained, which will make the theory interpretation error broaden. The migration mechanism of numerical simulation interpretation method to interwell tracer test can’t be described accurately, the workload is big, and the solution stability is bad. From the angle of the reservoir engineering, based on the flow line method and not stable filtrate field, a more perfect semi-analytic method system for output concentration calculation of interwell tracer was build in this paper. It included pressure field resolution, particle tracing method, and the flow field decomposition method, which made a three-dimensional problem solving process become a combined form of solutions for linear dimension. The interpretation software for interwell tracer test was developed, based on the system of streamline solving method, and a practical and reliable interpretation method for interwell tracer test was formed. The software was applied to field test in a block reservoir of one domestic oilfield, and had acquired preferable effect.
