Abstract

Se describen fluidos de alta densidad y bajo contenido de solidos que son utiles como fluidos para perforacion, reacondicionamiento y completamiento ysimilares en operaciones en pozos gasíferos y petrolíferos. Los fluidos contienen unasalm uera que tiene disuelta en la misma una sal de zinc, tal comobromuro de zinc, opcionalmente 1 o más sales solubles en agua adicionales, un viscosificador que es un sílice de área superficial elevada, un viscosificadorbiopolimérico, un aditivode co ntrol de pérdida de fluido que preferiblemente es un derivado de almidon, carbonato de zinc y opcionalmenteun buffer alcalino, un aditivo polar y un agente formador de puente. Se ha hallado que el carbonato de zincaumentará la viscosidad del bajo régimen decorte de los fluidos que contienen una sal de zinc disuelta en los mismos. Adicionalmente la combinacion de carbonato de zinc y oxido de zinc como bufferalcalino proporciona fluidos que tienenestabilidad térmica i ncrementada segun se indica por la viscosidad de bajo régimen de corte de los fluidos. Sedescribe además un método para aumentar la viscosidad del régimen de bajo corte de dicho fluido.
