Abstract
Description
technical field
[0001] The present invention relates to a synthesis method and an application method of a new type of tracer—"BYP tracer". The synthesis process innovatively utilizes the "alternative ion transfer method between multiphases", and successfully synthesizes "BYP tracer", which is a fluorescent nanomaterial with a core-shell structure, especially as an oil field well tracer. , plays an important role in the process of detecting reservoirs and testing the distribution and movement of reservoir fluids. Background technique
[0002] In the water injection development of complex fault-block oilfields, due to the heterogeneity of the oil layer itself, high permeability zones or large pores will gradually form between oil and water wells, the efficiency of water flooding will decrease, the water cut of oil wells will rise sharply, and the development effect will obviously deteriorate. The tracer can qualitatively judge the existence of high permeability zones or large...
