Abstract

The invention relates to a synthetic method and application method of a BYT tracer. Rare-earth element tracing method is one of effective measures to detect oil reservoirs in oilfields. A fluorescentnano material with core-shell structure is synthesized herein and may act as an oilfield tracer, named as BYT tracer. The tracer herein has the advantages of good water solubility, low usage, low water sample demand, good analytical simplicity, high analytical sensitivity, zero radiation, low toxicity, every low environmental impact, zero impact on mineralization degree, good compatibility with polymers, and zero impact on polymer flooding. The application of the BYT tracer as one fluorescent nano material in the field of oilfield detection is innovatively achieved herein; a feasible operatingscheme is provided as well.

Description

technical field

[0001] The invention relates to a synthesis method and an application method of a novel "BYT" tracer. During the synthesis process, the innovative use of "multi-phase ion alternating transfer method" successfully synthesized the "BYT" tracer, which is a fluorescent nanomaterial with a core-shell structure, and it is a good interwell tracer in oil fields , which 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 interwell tr...
