U.S.: Use of Microorganisms to Improve Oil Recovery
According to a report from the Daily Science Network on August 2, researchers at Oregon State University in the United States have adopted a new "microbial enhanced oil recovery" technology that can not only allow existing wells to produce more oil, but also can be applied to oil spills. And the cleanup of pollutants. The study was published in the latest issue of the Journal of Petroleum Science and Engineering.
The method of enhancing oil recovery by microorganisms was developed several decades ago, but due to the high costs at that time, the inconsistent results of operations in this field, and the lack of understanding of what actually happened in the ground, it is rarely used in oil drilling. use. With conventional technology, only 30% to 50% of the crude oil can generally be mined, and a large amount of oil, especially high-viscosity oil, remains in the reservoir. As a result, the method by which microorganisms enhance oil recovery has gradually become the best known technique for recovering remaining oil and depleted reservoirs in a reservoir. In addition, it also plays a certain role in cleaning up the leakage or improper discharge of oil exploration and production, transportation and storage, refining and use.
The new technology is to inject microbes into the well after the water is injected into the well, and feed them with sugar similar to molasses as feed to promote their growth. In this way they can block some of the interstices of the media and act as a surfactant, as the dishwasher removes grease from the pot, loosening the crude oil from the surface to which it adheres.
The researchers said: “Blocking some pores in subterranean media, the method of moving the above crude oil is easier than other methods. In theory, it can help to obtain a considerable amount of oil more than the traditional way of flushing with clean water. This surface can be man-made, and let the microorganisms produce it, the cost will be very low."
The researchers found that although it is necessary to combine with biosurfactant technology to achieve the best oil recovery, this “plugging mechanism†is simple and efficient to use and practical. This way of optimizing oil production can get more oil and can win more profits in business. Moreover, an additional benefit of this technology is that it can help remove or clean up underground pollutants. (Hua Ling)
These beads are coated with a special coating during the manufacture of the glass beads. In the rainy and foggy weather, the moisture can not easily adhere on the surface of glass beads, so the effection on reflectivity caused by bad weather will be reduced. The granulometry of this type glass beads is the same as non-coated glass beads.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
