Oil Exploration

Apr 21, 2023

Petroleum is our important energy and chemical raw material, and has a pivotal position in the national economy. Chinese polymer flooding oil quantity ranks first in the world. Become the world's largest polymer flooding oil production country. At present, the international crude oil price continues to rise, stimulate the measures of crude oil exploitation in various countries. Tertiary oil recovery, which takes polyacrylamide flooding and enhanced oil recovery technology as the core, will become the dominant development mode and enter the rapid development period.


At present, the formation temperature of class Ⅱ and Ⅲ reservoir resources is 70-95℃, the formation salinity is 10,000-30,000 mg/l, and the divalent ions are 800mg/l. Under such conditions, the commonly used polyacrylamide will appear serious thermal degradation, the degree of hydrolysis is increased, and the high value ions are combined to precipitate, and the viscosification effect becomes poor. The thermo-salt-resistant polyacrylamide produced by our company can meet the requirements of viscosity, temperature resistance, salt resistance, shear resistance and so on under reservoir conditions, and has good oil displacement performance.


Polyacrylamide is also widely used in profile control, water plugging agent, drilling fluid, fracturing fluid and so on. It plays an important role in fluid loss reduction, flocculation, shale suppression, dilution, plugging, cooling and lubrication of drill bit and string, cuttings carrying, cementing, etc.
