Analiza wpływu nanomateriałów na właściwości osadu filtracyjnego W artykule przedstawiono wyniki badań nad doborem stężenia nanokrzemionki hydrofobowej oraz innych składników do płuczki wiertniczej, zapewniających uzyskanie stabilnych parametrów reologicznych i niskiej filtracji w warunkach otworopodobnych. Opisano badania nad określeniem wpływu dodatku nanokrzemionki i mikrokrzemionki oraz środków powierzchniowo czynnych na parametry reologiczne, filtrację API i HPHT oraz właściwości inhibitacyjne opracowanych płu-czek wiertniczych. W dalszej części artykułu przedstawiono wyniki badań przyczepności kamienia cementowego do skał, na powierzchni których utworzyły się osady z badanych płuczek, oraz skuteczności usuwania tych osadów przez ciecz przemywającą. Na podstawie przeprowadzonych badań zaproponowano składy płuczek zawierających nanokrzemionkę hydrofobową dyspergowaną w poliglikolu w połączeniu ze środkami powierzchniowo czynnymi oraz mikrokrzemionke.Słowa kluczowe: płuczka wiertnicza, nanomateriały, nanokrzemionka, mikrokrzemionka, osad iłowy.
Analysis of the effect of nanomaterials on the properties of filter cakeThe article presents results of research on the choice of hydrophobic silica nanoparticles and other components concentration in the drilling fluid, that ensures stable rheological parameters and low water loss in borehole conditions. Studies to determine the effect of nanosilica, microsilica and surfactants additions on rheological parameters, inhibition properties, API and HPHT filtration of prepared drilling fluids were described. The following section presents the results of adhesion tests of cement stone to rocks, on which sediment from the scrubbers was formed, and the efficiency of removing these sediments from the washing liquid. Based on the laboratory study, a drilling fluid composition containing a hydrophobic nanosilica dispersed in a polyglycol in combination with surfactants and microsilica was proposed.
An analysis of the possibilities of using new types of polymeric inhibitors in the technology of drilling fluids in shale formations The paper presents an overview of the currently used inhibited drilling fluids with the ability to reduce the hydration of the shale. Based on literature data the possibility of using drilling muds in shale formations was analysed. The rest of the article presents the results of research intended to select new chemicals used as inhibitors of the hydration of rocks in drilling muds for drilling in shale. In this study agents such as a new type of polyglycol, an alkoxy derivative of butanol and an amine compound were used. New types of inhibitors were used in the composition of drilling fluids developed for drilling in shale. The carried out investigations of thermal resistance, resistance to pollution with mono-and multivalent ions, and studies on their impact on the disintegration of Miocene shale have shown that the developed muds have suitable technological parameters, are resistant to pollution with bivalent metal ions and temperature, and provide effective protection against Miocene shale hydration up to 100%. The investigations were performed under the Blue Gas project.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
