“…CMC and cellulose-related compounds were not new materials in drilling industries. These compounds frequently are used as additives in water-based drilling mud to reduce fluid loss in mud, to confer water-holding properties on mud, and to assure its appropriate rheology at elevated temperature [16][17][18][19][20].…”

A self-degradable alkali-activated cementitious material consisting of a sodium silicate activator, slag, Class C fly ash, and sodium carboxymethyl cellulose (CMC) additive was formulated as one dry mix component, and we evaluated its potential in laboratory for use as a temporary sealing material for Enhanced Geothermal System (EGS) wells. The self-degradation of alkali-activated cementitious material (AACM) occurred, when AACM heated at temperatures of ≥ 200°C came in contact with water. We interpreted the mechanism of this water-initiated self-degradation as resulting from the in-situ exothermic reactions between the reactants yielded from the dissolution of the nonreacted or partially reacted sodium silicate activator and the thermal degradation of the CMC. The magnitude of self-degradation depended on the CMC content; its effective content in promoting degradation was ≥ 0.7 %. In contrast, no self-degradation was

“…Dentre os aditivos mais comuns e rotineiramente utilizados em fluidos como viscosificante e redutor de filtrado, destaca-se o carboximetilcelulose (CMC) polímero aniô-nico, natural modificado derivado da celulose. O uso de tal aditivo reduz as perdas por filtração e produz rebocos muito finos e capazes de impedir o escoamento do fluido através das formações geológicas que estão sendo perfuradas além de manter as propriedades de fluxo adequadas mesmo em condições de alta temperatura, alta salinidade e alta pressão [6][7][8][9][10][11].…”

ResumoA influência da carboximetilcelulose, CMC, (redutor de filtrado) e da goma xantana (viscosificante), nas viscosidades aparente e plástica, no limite de escoamento e no volume de filtrado na composição de fluidos de perfuração à base de água foi investigada com base no delineamento estatístico. Cinco formulações compostas por uma faixa de concentração utilizada comercialmente foram utilizadas na concepção da experiência. As formulações foram preparadas de acordo com os padrões da empresa Petrobras. Foram calculados modelos de regressão, correlacionando as propriedades com as composições. A importância e a validação dos modelos foram confirmadas pela análise estatística. O desenho estatístico pode ser aplicado para otimizar as propriedades da lama considerando adição de CMC e da goma xantana, e para obter um melhor entendimento sobre a influência de aditivos sobre as propriedades de polímeros de sistemas de fluidos de base água. A partir do estudo observou-se que os valores das propriedades reológicas variaram com a concentração dos aditivos, aumentando com o aumento da concentração dos mesmos, e que o aumento da concentração dos aditivos promoveu uma diminuição dos valores dos parâmetros de filtração.

EFFECTS OF PROPERTIES POLYMERIC ADDITIVES IN RHEOLOGIC AND DRILLING FLUIDS AbstractThe influence of carboxymethylcellulose, CMC (filtrate reducer) and xanthan gum (viscosifier) in plastic and apparent viscosity at yield strength and the volume of filtrate in the composition of drilling fluids based on water was investigated based on statistical design. Five formulations consist of a range of concentrations used commercially were utilized in the design of the experiment. The formulations were prepared in accordance with company standards Petrobras. Regression models were calculated and correlated with the properties of the compositions. The relevance and validation of the models were confirmed by statistical analysis. The design can be applied to statistically optimize the mud properties considering the addition of CMC and xanthan gum, and to provide a better understanding of the influence of additives on the properties of polymer-based fluid system water. From the study it was observed that the values of the rheological properties vary with the concentration of additives, increasing with increasing concentration of the same, and that the concentration of the additives caused a decline of parameter values filtration.

INTRODUÇÃOA incorporação de polímeros como componentes de fluidos de perfuração figura atualmente como uma das principais alternativas para adequação das propriedades que o fluido deve apresentar na atividade de perfuração de poços de petróleo [1].Os fluidos de perfuração apresentam várias propriedades físico-químicas que devem ser levadas em consideração durante sua aplicação [2]. As soluções poliméricas colocam-se como ...
