1. Application of polyacrylamide flocculant in oil recovery: Polyacrylamide flocculant plays an important role in oil recovery due to its properties of thickening, flocculation and regulating the rheology of fluids. It is widely used in drilling water plugging, acidizing water, fracturing, well cleaning, completion, drag reduction, scale prevention and oil displacement. In general, the use of polyacrylamide flocculants is to improve oil recovery rates. In particular, many oil fields have entered secondary and tertiary exploitation. The depth of oil reservoirs is generally above 10%, and some oil reservoirs are as deep as 100%. The heterogeneity of formations and offshore oil fields have put forward more stringent conditions for oil production operations. Deep oil production and offshore oil production Correspondingly, new requirements have also been put forward, requiring it to be resistant to shear force, resistant to high temperatures above ℃ to ℃, and resistant to calcium ions and magnesium ions, and resistant to seawater degradation.
Dipolyacrylamide is used as a drilling fluid conditioner and fracturing fluid additive
As a drilling fluid conditioner, partially hydrolyzed polyacrylamide is often used, which is obtained by hydrolysis of polyacrylamide. Its function is to adjust the rheology of drilling fluid, carry cuttings, lubricate the drill bit, reduce fluid loss, etc. The drilling fluid prepared with polyacrylamide has a low specific gravity, which can reduce the pressure and blockage of oil and gas layers, easily discover oil and gas layers, and is beneficial to drilling. The drilling speed is higher than conventional drilling fluids and about higher than the mechanical drilling speed.
In addition, it can also greatly reduce drill stuck accidents, reduce equipment wear, and prevent well leakage and collapse.
Fracturing technology is an important production-increasing measure for developing tight layers in oil fields. Fracturing fluids cross-linked with methylene polyacrylamide are widely used due to their high viscosity, low friction, good sand suspension capacity, low filter loss, low viscosity, good stability, low residue, wide supply, convenient preparation and low cost.
In the fracturing and acidification treatment, the polyacrylamide flocculant is prepared into an aqueous solution with a concentration of 0.0%, and is pumped into the underground formation to cause the formation to fracture. Polyacrylamide flocculant aqueous solution has the function of thickening sand and reducing fracturing fluid loss. Moreover, polyacrylamide has a drag-reducing effect, thus reducing pressure transmission loss.
