Abstract

"ADITIVO PARA AUMENTAR A DENSIDADE DE UM FLUIDO PARA CONTROLAR A PRESSãO DE UMA ARMAçãO CIRCULAR". Um método de controle da pressão de um espaço anular de revestimento em um poço subterrâneo, que inclui a injeção no espaço anular de revestimento de uma composição que inclui um fluido de base e um material sólido coloidal revestido com polímero. O material sólido coloidal revestido com polímero inclui: uma partícula sólida que tem um diâmetro de partícula médio em peso (d~ 50~) de menos de dois mícrons, e um agente de dispersão polimérico revestido sobre a superfície da partícula sólida durante o processo de pulverização (isto é, moagem) utilizado para a feitura das partículas coloidais. O agente de dispersão polimérico pode ser um polímero solúvel em água tendo um peso molecular de pelo menos 2000 Daltons. O material em partículas sólidas pode ser selecionado a partir de materiais tendo um peso específico de pelo menos 2,68 e, preferencialmente, o material em partículas sólidas pode ser selecionado a partir de sulfato de bário (barita), carbonato de cálcio, dolomita, ilmenita, hematita, olivina, siderita, sulfato de estróncio e combinações e misturas destes e de outros sólidos similares que devem ser evidentes para alguém versado na técnica.
