Oil Field Polyacrylamide
Oil Field Polyacrylamide
It can improve the size of suspended particles, increase suspension force and accelerate the filtration and separation of crude oil.
Oilfield additive polyacrylamide is a multi-functional additive. It is used in mud conditioning agent, stabilizer and sedimentation flocculation in oil field drilling process to improve mud rheology. It can improve the size of suspended particles, increase suspension force and accelerate the filtration and separation of crude oil. As a soil structure shaping agent, the anti-impact performance of the wellbore surface is improved, and the non-dispersible slurry can be separated efficiently when drilling through the opening of the formation. Hydroxymethylation of partial hydrolyzed homogeneous polyacrylamide with formaldehyde and glyoxal to produce side chain methyl-containing products can achieve satisfactory results in crude oil production.
Enhanced Oil Recovery:
GO has been cooperating with several well-known oil fields in China for 15 years. For example, Shengli Oilfield, Daqing Oilfield and Zhongyuan Oilfield. The special polyacrylamide for tertiary production of oilfields is also in constant cooperation, and the products are maturing. Boyuan Water Purification Technology Department has studied oil displacement agent for tertiary oil recovery for thousands of times. High molecular weight, high viscosity polyacrylamide was customized. In Boyuan’s experiments and large-scale production, a new ultra-high molecular weight anionic polyacrylamide with molecular weight greater than 25 million, viscosity greater than 40 CP and degree of hydrolysis between 25% and 30% was synthesized by pre-alkali hydrolysis process and two-stage polymerization with acrylamide as the main monomer in aqueous solution. Through a lot of experiments, the optimum technological conditions were obtained as follows: initiator Y1 dosage 200 ppm, potassium persulfate 10 ppm, sodium bisulfite 150 ppm, PH value 8.5-9.5, polymerization concentration 23%, polymerization temperature 10 C, additive urea 5%, sodium formate 50 ppm. The products produced by this method are sold to Shengli Oilfield, Daqing Oilfield and Zhongyuan Oilfield, which have greatly improved the original recovery factor and greatly reduced the production cost.
Polyacrylamide for tertiary oil recovery in Boyuan Oilfield has established its leading position in the industry after more than 10 years of market testing. Please feel free to cooperate. Choose Boyuan products, your best choice
