Polymer gel has attracted extensive attention as an effective agent for profile control development enters middle and late stage. However, formation heterogeneity the unclear mechanism of with different strength severely limits displacement effect. In this work, microstructure viscosity polymer gels concentrations were characterized. The injection behavior experiments carried out to calculate breakout pressure plugging rate. core flooding performed obtain remaining oil saturation field...
Abstract The recovery efficiency by polymer flooding is 10% higher than that of water for main reservoirs in Daqing Oil Field, and yearly oil production rate injection has continuously reached over 10 million tons 8 years. However, to further enhance recovery, it very important know how many remained the after as well its distribution. paper took use logging data 200 new drilling wells make macro analysis on remaining distribution injection, based coring wells, collected from same group...
Abstract Polymer gels have received an increasing attention as profile control agents in the heterogeneous reservoir water-flooded layers. The article focus on mechanism of polymer by plugging macropore. micro-structures gel and pore were characterized scanning electron microscopy (SEM). And core displacement equipment was used to evaluate properties properties. variation structure is measured SEM, mercury intrusion meter nuclear magnetic resonance instrument. Investigation results show that...
Abstract In the process of oil displacement ASP (Alkali/Surfactant/Polymer) flooding, when Alkali interacts with fluid and minerals reservoir, alkali is subject to be consumed. The consumption regularity key factor affecting ingredient, injection plan, scaling for production wells effectiveness. Therefore study great significance in guiding project design, analysis mechanism. this paper, aiming at main components reservoir Daqing Oilfield, laboratory on static five kinds (kaolinite,...
Over the past decades, CO 2 flooding in low-permeability porous media has continued to grow. Furthermore, propelled by current movement toward sequestration, of is expected further increase. Thus, it scientific significance study mechanism displacement as well storage characteristics. In this study, miscible/immiscible experiments were conducted on two low permeability samples difference between them. Specifically, effect oil and coefficient for different models measured compared. addition,...
Abstract Aiming at the low viscosity of polymer solution, which is compounded with fresh water but diluted produced water, and problems concerning oil displacement efficiency, an onsite test on solution stabilizer (PSVS) carried out. As a result, it has great guiding significance to application popularization by studying performance its influence efficiency. In this paper, aiming two different kinds solutions among one other aerated laboratory evaluative tests stabilization, anti-shear...
Fracture initiation expansion and external fluid sensitivity evaluation have become the main focus of coal reservoir fracturing effect. Therefore, a study on fracture propagation hydraulic coupling mechanism between pore structure reservoirs need to be studied. In this paper, conductivity were carried out. First, an automatic simulation tester large-scale computed tomography scanner are used compare distribution calcite content evaluate effects different fluids construction parameters....
Abstract Miscible CO2 flooding gains rising popularity due to high displacement efficiency and potential carbon negativity. It is well documented that pore-level heterogeneity one of the dominant mechanisms responsible for variation in oil recovery efficiencies miscible flooding. However, owing a lack understanding behaviors at pore level, quantitative analysis influence on remains problematical. Recently, NMR has been widely used investigate microscopic residual distribution various agents....
