Abstract
Međupovršinska napetost najvažniji je parametar kemijskog EOR-a. Smanjivanjem međupovršinske napetosti između sirove nafte i vode u ležištima, nafta postaje mobilna faza te se povećava ukupni iscrpak. Pedant drop metoda omogućava brzo i jednostavno određivanje međupovršinske napetosti. Temelji se na analizi fotografije, a razmatra se promjena oblika kapljice fluida koja visi na kapilari okruženom drugim fluidom. Dvije sile koje utječu na promjenu oblika kapljice su gravitacijska sila i međupovršinska napetost. Smanjivanje međupovršinske napetosti postiže se utiskivanjem vodene otopine surfaktanata (površinski aktivnih tvari) u ležište koji se zbog specifične strukture molekula adsorbiraju na površinu kapljica nafte.
Abstract (english)
Interfacial tension is the most important parameter of chemical EOR. The result of lowering the interfacial tension between crude oil and brine is that oil becomes more mobile and therefore, more oil is produced. Pendant drop method is a simple and fast method provides determination of the interfacial tension. The method is based on analysing a change in shape of fluid drop which is suspended from capillary tip and surrounded with another fluid. Forces affecting the shape of a drop are gravity and interfacial tension. Lowering of interfacial tension is achieved by surfactant flooding. The result of the specific molecularstructure of surfactants is adsorbed on the oil drop surface.
