REDUCING WATER PRODUCTION IN OIL WELLS BY POLYMER INJECTION: AN IMPROVED METHODCHAUVETEAU, GMOULU, J C
The plugging of the oil well sand control area in a polymer flooding region was studied and the plugging substances were analyzed through UV-Vis spectrophotometer analysis, plasma emission spectrometry analysis, laser particle size analysis, X-Ray Diffra
In many viscous oil wells and polymer injection wells,because of viscous oil and heavy load,the crank-balanced unit used is lacking balance and its effect is poor with low balance rate,thus energy consumption is raised. 许多稠油井、注聚井游梁式抽油机因为油稠、负荷重,采用目前的曲柄平衡存在...
Through industrial scale application,change properly of water cut of polymer flooding oil wells in type Ⅱ oil layers was studied deeply. Based on the decline curve of water cut,il was divided into five types,in which round kettle type has good polymer flooding effect and large decrease of ...
In the large-scale polymer injection project, one pump per multiple wells not only increases the construction cost, but also impose on the maintenance workloads. In this concern, capillary flow regulator is developed and tailored for the injection technology of one pump per multiple wells. One pum...
Based on the basic geological features of the reservoir in LD10-1 oilfield,and combined with the dynamic characteristics of injection wells and flooding experiments on reservoir cores,the damage factors of the reservoir were analyzed using X-ray diffraction,electron microscope scanning and energy spectru...
A process is provided for reducing the pressure for injecting a solution of water-soluble polymer from a given injection pump into various oil wells in a given field as a function o
1997). Therefore several nature inspired optimization algorithms has evaluated in real oil field production problem conducted to obtain optimal polymer injection strategy. 1.2. The polymer injection problem Waterflooding is the most widely used oil recovery method after primary depletion (Littmann, 1988, ...
To solve the problems of blocking in polymer injection wells and further perfecting the technologic series of blockage removing and augmented injection in offshore oilfields,the situation of technological application of blocking removal and augmented injection in offshore oilfields was extensively introduced...
Enhanced Oil Recovery (EOR) is a process that extends reservoir life through field operations that aim to increase reservoir displacement efficiency. Injection of polymeric solutions, which is a chemical EOR process, improves sweep efficiency by decreasing the mobility of the injected fluids. One chall...
