IMPROVING DIVERSION BY COMBINING DISSOLVABLE AND DEGRADABLE PARTICLES AND FIBERS
In downhole treatments in the oilfield, ball sealers seated in perforations may not fully seal and may leak fluid through gaps and asperities between the balls and the perforations.

description | In downhole treatments in the oilfield, ball sealers seated in perforations may not fully seal and may leak fluid through gaps and asperities between the balls and the perforations. A method is given for improving the sealing of ball sealers in perforations by adding a sealing agent that forms a plug in the gaps and severely restricts or eliminates fluid flow. The sealing agent is preferably degradable or soluble, malleable fibers slightly larger than the gaps. Optionally, the particles may be non-degradable, rigid, of different shapes, and smaller than the gaps but able to bridge them. Mixtures of sealing agents may be used. The sealing agent may be added with the ball sealers, after the ball sealers, or both.
En los tratamientos del fondo de pozo en el campo de petróleo, los selladores de bola asentados en las perforaciones pueden no sellar completamente y pueden presentar fugas de fluido a través de las separaciones y las asperezas entre las bolas y las perforaciones. Se presenta un método que mejora el sellado de los selladores de bola en las perforaciones mediante la adición de un agente de sellado que forma un tapón en las separaciones y restringe severamente o elimina el flujo del fluido. El agente de sellado es preferentemente degradable o soluble, de fibras maleables ligeramente más grandes que las separaciones. Opcionalmente, las partículas pueden ser no degradables, rígidas, de diferentes formas, y más pequeñas que las separaciones pero capaces de formar un puente entre ellas. Las mezclas de agentes de sellado pueden usarse. El agente de sellado puede añadirse con los selladores de bola, después de los selladores de bola, o ambos. |
