With the development of oil fields, after a long-term water, produced liquid water content gradually increased, oily water reinjection imperative. Benefits were reinjected with oily water a lot, it has good compatibility with the formation, can prevent the formation of oil clogging the pores in the clay, but the great difficulty of oily wastewater fine filtration technology, it not only to control the effluent suspended solids content and grain What is the diameter of the fiber bundle diameter? But also to solve the sewage pollution of the oil filter. Daqing Oilfield has entered the late high water cut mining, with the deepening of EOR and expand, especially polymer flooding, flooding ternary development, so that the produced water into a complex polymer injection of oily wastewater system, water separator greatly increased the difficulty. At the same time due to the need for oil field development, the process of water increases, the processing requirements further. Existing waterflood oily wastewater treatment process has been unable to meet the increasingly complex polymer injection of oily wastewater treatment requirements. In this case, the urgent need to find a good filtering effect, stable performance, adaptability filtering techniques. There are now a lot of fiber filter manufacturers, but how to distinguish between true and false fiber ball filter it? Fiber ball filter is made of fiber Sizha knot made, due to the choice of different raw materials and process technology, production out of the fiber ball filter is not the same. But once you have the following points, you can easily grasp the important differential points. 1: The water content of the test fiber ball filter, fiber ball filter itself lighter texture, so it is very light physical weight, if a customer purchases fiber ball filter itself is relatively heavy, then we would make on the water content test, if the moisture content is too high, it means that there is the phenomenon of adulteration, which is relatively easy because of the difference. 2: The difference between willful and intensity, high-quality fiber ball filter has a very good self-willed and strength, hand-pulled, the phenomenon does not appear out of silk fibers, high strength. Poor quality fiber ball filter is generally more brittle fiber bundle where the price of cheap, hand pull move, there will be a phenomenon of broken wires. 3: Note whether native fiber ball filter, which can be performed on the color difference, the native white fiber ball filter without any impurities, color reproduction is relatively dim. 4: its treatment effect is good tow how to sell, this is generally only use the process before they can find. 5: cable tie knot tie knot in fiber ball filter used in the process, not only a good line in the pre-tied knot tight and difficult to corrosion during the latter part of the operation, leading to the problem of fiber ball loose. Fiber ball filter quality and price is directly proportional to the good quality fiber ball relatively high prices, but to ensure the security of the late use.
