| titleOfInvention | A metal tracer coated proppant for fracturing and its preparation method and application |
| abstract | The invention discloses a metal tracer coated proppant for fracturing and a preparation method and application thereof, belonging to the technical field of oilfield drilling and solving the problems of short validity period, poor thermal stability, low recovery rate and formation adsorption loss of other tracers. Large, low detection precision and other technical problems. The method for preparing a metal tracer film-coated proppant for fracturing uses a resin polymer to solidify to form a film-coated agent stock solution, which can improve the anti-extrusion ability between the ceramsite proppant; After the polymer coating is in contact, the metal tracer slowly diffuses into the formation through the pores in the polymer framework to achieve slow release and accurate detection. The method is simple to operate, safe and pollution-free, and can be industrially produced. The metal tracer film-coated proppant for fracturing is non-radioactive, non-polluting, stable in chemical and biological properties, and has high analytical precision, and its excellent traceability makes it not restricted by reservoir properties and fluid properties. |
