How to significantly improve oil recovery is a major issue facing the oil industry. Increasing the recovery mechanism from the microscopic scale is an important way to improve oil recovery. Studying the pore-level microscopic flow theory can quantitatively describe the microscopic flow mechanism, and thus develop a method for greatly improving recovery. The project carried out the study of microscopic flow theory from the pore-scale scale, and created a brand-new seepage theory, which established a basic platform for the study of pore-level microscopic flow theory and has important scientific value.
When this technology is mature, it will greatly improve the current experimental methods of reservoir physics that are commonly used. Some information that is difficult or impossible to obtain experimentally (such as the study of the three-phase permeability curve of oil and gas) can be obtained through the application of this technology. Therefore, the study of the theory and technology of reservoir seepage in the pore scale is of great significance to greatly increase the recovery ratio. At present, the scientific research results have been applied in the Shengli Oilfield Branch of Sinopec, and have achieved good results.
The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.
