Product Details
It plays an important role in the oil industry. As an oilfield additive, polyacrylamide for oilfield drilling has excellent characteristics such as fluid loss reduction, thickening, flocculation and friction reduction, which makes it used for drag reduction and acidification of water, fracturing, well flushing, drilling, completion, scale prevention, water plugging, and oil displacement, such as water plugging regulator, drilling fluid regulator and fracturing fluid additive, oil well cement additive, drilling fluid additive, completion fluid and workover fluid additive, oilfield water treatment agent and so on ...... in general, polyacrylamide oil drilling has greatly increased the rate of oil exploitation.
At present, China's oil field exploitation has entered the middle and late stage, in order to improve the recovery rate of crude oil, the main promotion of polymer flooding and three-way compound flooding technology. By injecting polyacrylamide aqueous solution, the oil-water flow velocity ratio is improved, and the crude oil content in the produced material is increased. At present, the application of polyacrylamide in the oil field is not much. Due to the special geological conditions in China, Daqing Oilfield and Shengli Oilfield have begun to widely use polymer flooding technology.
Hydrolyzed polyacrylic acid gel and cross-linked polyacrylamide gel for oil field drilling are of great significance in the exploitation of oil and natural gas and other industries. Usually in the oilfield drilling process, they can be used to adjust the rheology of drilling fluid, control water loss, improve drilling fluid lubricity and collapse resistance, polyacrylamide adsorbed on the surface of metal or clay particles to form a liquid film, from solid surface friction into liquid friction, so as to lubricate drill bits and drilling tools, reduce the friction coefficient of mud cake, and reduce downhole accidents. The low solid phase drilling fluid formulated with them can not only increase the drilling rate, but also have the advantage of reducing formation contamination. Polyacrylamide gel is mainly used for plugging well leakage.
