Abstract
Patente de Invenção:<B>"MISTURAS APERFEIçOADAS DE COMPONENTES MúLTIPLOS PARA USO EM EXPLORAçãO GEOLóGICA"<D>. A invenção refere-se a misturas de componentes múltiplos escoáveis e bombeáveis com base em uma mistura de fases múltiplas de óleo e água contendo emulsificantes e, se desejado, outros auxiliares solúveis, emulsificaveis e ou dispersáveis, para o uso das mesmas em exploração por perfuração e/ou tratamento posterior dos poços perfurados dessa forma. A invenção é caracterizada pelo uso de emulsificantes ou sistemas de emulsificantes os quais, na mistura específica de componentes múltiplos em questão, levam a uma inversão de fase controlada pela temperaura em uma temperatura de invenção de fase (PIT) em uma faixa de temperatura da qual o limite superior está bastante ebaixo da temperatura de trabalho da mistura de componentes múltiplos, em exploração geológica, em que a parte com base em água da mistura de multi componentes é apresentada como uma fase dispersa (invertida) na fase contínua de óleo (emulsão de inversão água em óleo) enquanto o limite mais baixo dessa faixa de temperatura permite que a mistura de componentes múltiplos seja convertida em uma emulsão de óleo em água com uma fase aquosa contínua. Pelo menos emulsificantes ou sistemas de emulsificantes parcialmente não iónicos, com um PIT de 0 até 100‹C são especialmente adequados. A invenção permite que as exigências com relação ao desempenho técnico, compatibilidade ecológica e proporção de custo/eficiência sejam otimamente satisfeitas.Invention Patent: <B> "IMPROVED MIXTURES OF MULTIPLE COMPONENTS FOR USE IN GEOLOGICAL EXPLORATION" <D>. The invention relates to mixtures of multiple flowable and pumpable components based on a mixture of multiple phases of oil and water containing emulsifiers and, if desired, other soluble, emulsifiable and or dispersible auxiliaries, for their use in drilling exploration and / or further treatment of wells drilled in this way. The invention is characterized by the use of emulsifiers or emulsifier systems which, in the specific mixture of multiple components in question, lead to a temperature-controlled phase inversion at a phase invention temperature (PIT) in a temperature range from which the upper limit is well below the working temperature of the multi-component mixture, in geological exploration, where the water-based part of the multi-component mixture is presented as a dispersed (inverted) phase in the continuous oil phase (emulsion of water-to-oil inversion) while the lower limit of this temperature range allows the mixture of multiple components to be converted into an oil-in-water emulsion with a continuous aqueous phase. At least emulsifiers or partially nonionic emulsifiers systems, with a PIT of 0 to 100 ° C are especially suitable. The invention allows the requirements regarding technical performance, ecological compatibility and cost / efficiency ratio to be optimally met.
