The miscibility of flue gas and different types light oils is investigated through slender-tube miscible displacement experiment at high temperature pressure. Under the conditions pressure, oil possible. At same temperature, there a linear relationship between efficiency increases gently then rapidly to more than 90% achieve with increase temperature. rapid closely related process that components transit in phase state due distillation rise Moreover, lighter oil, lower minimum which allows...
Physical modeling, numerical simulation and field case analysis were carried out to find the subsurface thermal oxidation state, front characteristics production dynamic of high pressure air injection miscible flooding technology. The lighter composition lower viscosity crude oil, fuel consumption combustion temperature are. light oil volatile can advance stably, a medium-temperature stable displacement state be formed in reservoir under conditions. With strong gasification distillation, are...
A high-temperature and high-pressure experimental device was upgraded to accommodate a maximum pressure of 40 MPa temperature 800 °C. Using this device, one-dimensional oxidation displacement experiments were carried out via air injection in the Hudson original reservoir change from low (5 MPa) high (30 after water under 30 conditions. stable medium–high-temperature thermal front state could be formed different measurements 5 MPa, 15 experiment pressure, at which similar characteristics...
Currently, the development of oil reservoirs with high water cut faces numerous challenges, including poor economic efficiency, difficulties in residual recovery, and a lack effective technologies. In light these issues, this paper conducts research on gas drive during stage middle–high permeability introduces an innovative technical approach for air thermal miscible flooding. study, Enhanced Oil Recovery (EOR) mechanism dynamic characteristics flooding were investigated through laboratory...
Polyacrylamide (HPAM) and other traditional polymers have poor temperature resistance salinity tolerance do not meet the needs of high-temperature high-salinity reservoirs. In this study, a new temperature-resistant salinity-tolerant polymer QJ75-39 was synthesized using acrylamide (AM) as hydrophilic monomer, 1-acrylamide-2-methylpropanesulfonic acid (AMPS) N-vinylpyrrolidone (NVP) functional monomers DS-16 hydrophobic monomer. Through laboratory experiments, properties (temperature...
Summary An ultraheavy oil block is undergoing a dry in-situ combustion field test in the Xinjiang fields, China. However, this method faces problems of high air/oil ratio and low production rate. Researchers are exploring feasibility using wet to improve economic efficiency For purpose, it necessary study displacement characteristics water/air (WAR) limit reservoirs. In study, we investigated differences between by conducting 1D model tests. The results show that can transfer heat from...
Summary The problems of oil/steam ratio (OSR) and oil production decline are prominent during the middle/later stages steam-assisted gravity drainage (SAGD) in superheavy reservoirs. Using noncondensable gas (NCG) by SAGD can reduce heat loss to overburden carbon dioxide (CO2) emissions. However, date, laboratory experiments have mainly been conducted simulate NCG coinjection with steam early stage SAGD. There has limited research on into mature chamber. For this study, five sets 2D physical...
