Abstract

The invention relates to a synthetic method and application of a 'BYC tracer agent'. A rare earth element tracer method is one of effective methods to detect oil reservoirs in oil fields. A fluorescent nanomaterial with a core-shell structure is synthesized and can be used as an oil field tracer agent which is named as the 'BYC tracer agent'. The tracer agent has the advantages that the water solubility is good, the use amount is small, the exploration demand quantity of water samples is few, the analytical method is simple and convenient, and the analysis sensitivity is high; the tracer agenthas no radioactivity, low toxicity and a minimal impact on the environment; the degree of mineralization is not affected, the compatibility with polymers is good, and oil displacing of the polymers is not affected; the application of the BYC tracer agent, that is, the fluorescent nanomaterial in the field of oil field exploration is creatively achieved, and a feasible operation scheme is proposed.

Description

technical field

[0001] The present invention relates to a synthesis method and application method of a new type of tracer——"BYC tracer". During the synthesis process, the innovative use of the "multi-phase ion alternate transfer method" successfully synthesized "BYC tracer", which is a fluorescent nanomaterial with a core-shell structure, especially as an oil field well tracer. It plays an important role in 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 pores, and the interwe...
