The thermal conductivity of five samples crude oil and one sample gas condensate was measured by the transient hot-wire technique. measurements were made along isotherms (245, 250, 273, 295, 320, 336, 373 K) in pressure range from atmospheric up to 1000 MPa isobars (at 0.1, 100, 200, 300, 400, 500, MPa) temperature 245–450 K. It observed that investigated strongly depends on rises with increasing for all temperatures. At a certain pressure, coefficient reverses negative positive. at which...
When evaluating the effectiveness of heat exchange surfaces in main considered characteristics such as flow (Q, Watt), power required for pumps (N, and surface area transfer (F, m2). The most correct comparison provides a ceteris paribus. Carried out performance paribus in-line staggered configurations bundles with circular pipes can serve basis development physical models tube tubes other geometric shapes, considering intertubular stream attached eddies. effect longitudinal transverse steps...
An approach to predicting the viscosity and density of petroleum products using artificial neural networks was proposed. Based on reliable data thermophysical properties, products, models multi-layer with a different number hidden layers were developed, which trained an array experimental Levenberg-Marquardt Bayesian regularization algorithms. The test results showed that by algorithm are unable predict sufficient accuracy for practical purposes those values input signals not involved in...
Abstract Based on the principle of corresponding states, a method developed for prediction viscosity liquid petroleum products that differ significantly in physicochemical properties and fractional composition. New approaches to determination reduced temperature are proposed. The initial data computation molar mass, average volume boiling point relative density at 20 °C. Testing new technique range (0.4–0.7)T pc pressures up 10 MPa showed deviation predicted values from experimental is...
Abstract The article deals with the new technique for predicting viscosity of liquid petroleum products, which differ significantly in physicochemical properties and fractional composition, a wide range state parameters. No specific information is used to predict other than molar mass, average volume boiling point, relative density at 20 °C. It shown that deviation predicted values from experimental data comparable error measurement. Methods correcting calculation results using limited are...

ВведениеСостояние и фазовое поведение углеводородов в водонасыщенном продуктивном коллекторе представляют особый интерес.Присутствие воды природных нефтегазовых резервуарах проявляется различных формах и, частности, является одним из условий образования гидратов.Данные об условиях разложения гидратов смесей необходимы при оценке возможности гидратообразования пластовых скважинных системах.Термодинамические свойства, кинетика процессов метана, этана пропана уже детально изучены.В то же время...
This paper discusses the results of our comprehensive studies temperature-baric dependences effective thermal conductivity granites. For a detailed analysis, we selected some published experimental temperature and pressure number granites (as well as granitoids) in ranges ~273– 900 K 0.1–1500 MPa, which corresponds to parameters rocks from surface layer depths more than 50 km continental crust. A low-parametric description dependence is proposed, good agreement with data, at least range...
