A hidroxietilcelulose \u00e9 um pol\u00edmero n\u00e3o i\u00f4nico, sol\u00favel em \u00e1gua, que agora \u00e9 amplamente utilizado em muitos setores devido \u00e0 sua excelente capacidade reol\u00f3gica, capacidade de espessamento e compatibilidade com muitas formula\u00e7\u00f5es diferentes. Hidroxietilcelulose<\/span> na perfura\u00e7\u00e3o de petr\u00f3leo pode otimizar a perfura\u00e7\u00e3o, a cimenta\u00e7\u00e3o, o fraturamento hidr\u00e1ulico e outros aspectos.<\/span><\/p>\n

Import\u00e2ncia do HEC em aplica\u00e7\u00f5es de campos petrol\u00edferos<\/strong><\/h2>\n

O setor de campos petrol\u00edferos exige materiais especializados que possam suportar altas press\u00f5es, temperaturas extremas e uma ampla gama de condi\u00e7\u00f5es qu\u00edmicas. TENESSY\u00ae Hidroxietilcelulose<\/a> O HEC pode ser usado como aditivo em pastas de argila benton\u00edtica de salmoura n\u00e3o dispers\u00edvel na perfura\u00e7\u00e3o de petr\u00f3leo. Isso reduz a perda de \u00e1gua e aumenta a viscosidade sem aumentar a for\u00e7a do gel.<\/p>\n

Al\u00e9m disso, o uso de HEC em lamas de perfura\u00e7\u00e3o melhora a dispers\u00e3o da argila no po\u00e7o e evita o colapso do po\u00e7o. A versatilidade e os benef\u00edcios ambientais do HEC fazem dele um componente essencial da moderna tecnologia de campos petrol\u00edferos.<\/p>\n

HEC para fluidos de perfura\u00e7\u00e3o<\/strong><\/h3>\n

Os fluidos de perfura\u00e7\u00e3o, tamb\u00e9m conhecidos como lamas de perfura\u00e7\u00e3o, s\u00e3o usados para resfriar a broca de perfura\u00e7\u00e3o, estabilizar o po\u00e7o e transportar os detritos para a superf\u00edcie. Para garantir a seguran\u00e7a e a efici\u00eancia das opera\u00e7\u00f5es de perfura\u00e7\u00e3o, \u00e9 necess\u00e1rio manter o equil\u00edbrio adequado das propriedades dos fluidos.<\/p>\n

Os perfuradores geralmente utilizam fluidos de perfura\u00e7\u00e3o contendo hidroxietilcelulose para perfura\u00e7\u00e3o de rocha dura e perfura\u00e7\u00e3o em cen\u00e1rios exclusivos, incluindo forma\u00e7\u00f5es de xisto altas e baixas, anomalias de press\u00e3o, perda excessiva de \u00e1gua e gerenciamento de vazamento de \u00e1gua circulante. As opera\u00e7\u00f5es de perfura\u00e7\u00e3o de grandes furos e furos abertos tamb\u00e9m se beneficiam dele. Os operadores podem usar o HEC na lama de perfura\u00e7\u00e3o para resfriar as limalhas de ferro e os cortes de perfura\u00e7\u00e3o e traz\u00ea-los \u00e0 superf\u00edcie, aumentando a capacidade da lama de transportar rochas devido \u00e0s suas qualidades de espessamento, suspens\u00e3o e lubrifica\u00e7\u00e3o. Os fabricantes produzem a hidroxietilcelulose como um pol\u00edmero n\u00e3o i\u00f4nico e sol\u00favel em \u00e1gua. Muitos setores o utilizam atualmente devido \u00e0s suas excelentes propriedades reol\u00f3gicas, capacidade de espessamento e compatibilidade com v\u00e1rias formula\u00e7\u00f5es. No setor de campos petrol\u00edferos, o HEC desempenha um papel fundamental na otimiza\u00e7\u00e3o da perfura\u00e7\u00e3o, cimenta\u00e7\u00e3o e fraturamento hidr\u00e1ulico.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Os perfuradores tamb\u00e9m podem usar a hidroxietilcelulose em lamas de perfura\u00e7\u00e3o como um gel protetor n\u00e3o ferment\u00e1vel para tratamentos de po\u00e7os de petr\u00f3leo e para trabalhos de ensaio em altas press\u00f5es (20 MPa) e temperaturas. Os trabalhadores usam o HEC como agente espessante e cimentante em fluidos de recupera\u00e7\u00e3o de po\u00e7os de petr\u00f3leo. Ele ajuda a fornecer uma solu\u00e7\u00e3o clarificada com baixo conte\u00fado fixo, o que minimiza bastante os danos \u00e0 estrutura do po\u00e7o.<\/p>

Ela j\u00e1 foi usada como uma solu\u00e7\u00e3o de expans\u00e3o de po\u00e7o e transporte de areia, que foi eficaz e colocada em pr\u00e1tica. O uso de hidroxietilcelulose tamb\u00e9m pode melhorar muito as propriedades de perda de filtra\u00e7\u00e3o da lama e aumentar substancialmente a estabilidade da lama.<\/p>

HEC para completa\u00e7\u00e3o de po\u00e7os e workover<\/strong><\/h3>

Para concluir a constru\u00e7\u00e3o do po\u00e7o e prepar\u00e1-lo para a produ\u00e7\u00e3o, os operadores utilizam fluidos de completa\u00e7\u00e3o do po\u00e7o. Os trabalhadores usam fluidos de workover para reparar ou manter os po\u00e7os. Muitas atividades em campos petrol\u00edferos usam salmouras de alta salinidade como fluidos de base, e o TENESSY\u00ae HEC funciona bem com uma variedade de solu\u00e7\u00f5es de salmoura para proporcionar um desempenho confi\u00e1vel nessas condi\u00e7\u00f5es de alta salinidade.<\/p>

O HEC \u00e9 formulado como um fluido de completa\u00e7\u00e3o com baixo teor de s\u00f3lidos que evita que part\u00edculas de argila obstruam os vazios do reservat\u00f3rio \u00e0 medida que se aproxima da forma\u00e7\u00e3o, e a propriedade de redu\u00e7\u00e3o de perda de \u00e1gua evita que grandes quantidades de \u00e1gua entrem na forma\u00e7\u00e3o a partir da lama para garantir a produtividade da forma\u00e7\u00e3o.<\/p>

O TENESSY\u00ae HEC reduz o atrito da lama, o que, por sua vez, reduz a press\u00e3o da bomba e o consumo de energia. Sua excelente solubilidade em sal tamb\u00e9m garante que nenhum precipitado seja formado ao acidificar o po\u00e7o.<\/p>

HEC para fluido de fraturamento hidr\u00e1ulico<\/strong><\/h3>

Durante o fraturamento hidr\u00e1ulico, as empresas injetam um fluido de fraturamento de alta press\u00e3o na rocha para criar fraturas. Essa a\u00e7\u00e3o permite que o propante fique suspenso e se mova mais profundamente na fratura. Devido \u00e0 sua baixa toxicidade e biodegradabilidade, muitos escolhem a hidroxietilcelulose como uma alternativa ambientalmente mais aceit\u00e1vel aos aditivos qu\u00edmicos convencionais nos fluidos de fraturamento.<\/p>

Nos fluidos de fraturamento, o TENESSY\u00ae HEC aumenta a viscosidade e pode fraturar po\u00e7os de petr\u00f3leo sem afetar a forma\u00e7\u00e3o ou obstruir as fraturas. Os fluidos de fraturamento \u00e0 base de \u00e1gua feitos com HEC s\u00e3o essencialmente isentos de res\u00edduos ap\u00f3s a liquefa\u00e7\u00e3o, o que os torna particularmente adequados para forma\u00e7\u00f5es com baixa permeabilidade, onde n\u00e3o \u00e9 poss\u00edvel a retrodrenagem de res\u00edduos.\u00a0<\/span><\/p>

O HEC pode evitar a perda de viscosidade e a ruptura da forma\u00e7\u00e3o de \u00f3leo devido \u00e0 alta temperatura no fundo do po\u00e7o, e ainda tem melhor efeito em po\u00e7os com mais de 371\u00b0C. O HEC n\u00e3o se corrompe nem se deteriora facilmente no fundo do po\u00e7o, tem poucos res\u00edduos e n\u00e3o bloqueia o circuito de \u00f3leo nem causa polui\u00e7\u00e3o no fundo do po\u00e7o. Estudos demonstraram que o HEC tem o melhor desempenho ao comparar a efic\u00e1cia do CMC, MC, HPC e HEC como componentes do fluido de fraturamento.<\/p>
