For the last 20 years Shengli oilfield has done research into the application of microbial enhanced oil recovery (MEOR). The authors summarize and analyze MEOR progress in mechanism research and field application in Shengli oilfield. The results indicate MEOR could improve oil recovery after water flooding and polymer flooding with multiple mechanisms. Cumulative oil increment of MEOR application on seven blocks was 212,366 t. The research and application of MEOR should concentrate on air assisted microbial flooding and indigenous microbial flooding in the future. 相似文献

Wide use has been made of non-isothermic studies for obtaining kinetic data on the anionic polymerization of ?-caprolactam and ω-dodecalactam. Data are obtained by measuring changes in reaction temperature, under conditions of heat exchange with the surroundings and by solving the inverse thermophysical problem. This solution yields kinetic constants, which when substituted into heat conduction and kinetic equations minimize the deviations of calculated temperature dependences on time and the deviations in experimental data. Thus, we have studied qualitatively the polymerization of lactams. Numerical values of the basic kinetic constants in the macrokinetic scheme have been determined. Some new effects, such as self-acceleration in the polymerization of caprolactam and the increase of the apparent activation energy at high degrees of conversion in the polymerization of dodecalactam were detected. The approach may be useful in studying other polymerizations. 相似文献

Shape Memory Alloy ( SMA ) optically activated is the key technology of optical SMA activator.According to the shape memory mechanism of SMA, researches are done on the activating response time and light wavelength of activating source etc of SMA optically activated to approach the parameters selection of optical activation. SMA has the optimum efficiency in the range of 13 seconds to 27 seconds when SMA is illuminated continuously by wavelength of 675um; The power of light wave has a low effect on SMA; The longer the activating wavelength, the quicker the response time of SMA activated. If the proper activating time and activating wavelength are adopted, and the structure deformation of composite material of SMA imbedded may be actively controlled, an ideal effect will be gotten. The research provides an evidence for the design of optical SMA activator and is of great significance to its application. The research on smart structure has a wide application prospect. 相似文献
