Oil Drilling Anionic Polyacrylamide

Qingdao Shuodi Environmental Protection Technology Co., Ltd. is a Chinese factory for the research and production of anionic polyacrylamide for oil drilling. Non-ionic polyacrylamide and cross-linking agent wake up oxidation-reduction reaction to cross-link to form gel, which can be used as water shutoff agent for oil wells; oil drilling anionic polyacrylamide is used as drilling mud additive because of its excellent thickening and flocculation effects .

It is used in geology and oil drilling to adjust mud properties, and has special effects on resisting water-sensitive formations and preventing well wall collapse. In addition, using the shear orientation of the anionic polyacrylamide linear macromolecular structure in the flowing fluid, it is easy to be oriented into a long strip in the flow direction under the turbulent state. Resist turbulence development, oil drilling anionic polyacrylamide is a very ideal material as a friction reducing agent. For example, in the long-distance pipeline transportation of crude oil, it is only necessary to add oil drilling anionic polyacrylamide with a molecular weight of more than 10 million equivalent to 0.1PPM of crude oil, which can greatly reduce the resistance during crude oil transportation and reduce energy consumption. In the middle and late stages of oil exploitation, in order to enhance oil recovery, polymer flooding and ASP flooding technologies are mainly promoted at present. By injecting an anionic polyacrylamide aqueous solution into oil drilling wells, the oil-water flow rate ratio is improved, and the crude oil content in the produced product is increased.

Adding oil drilling anionic polyacrylamide in the tertiary oil recovery can increase the oil displacement capacity, avoid breakdown of the oil layer, and increase the recovery rate of the oil bed.

Oil drilling anionic polyacrylamide indicators:

The main application of oil drilling anionic polyacrylamide:

1. Oil displacement agent for tertiary oil recovery in oil fields: it can adjust the rheology of injected water, increase the viscosity of driving fluid, improve the sweep efficiency of water flooding, reduce the permeability of water phase in the formation, so that water and oil can flow forward at a uniform speed. Its function is mainly used in the tertiary oil recovery of oil fields in terms of oil exploitation. Every time polyacrylamide product is injected, more crude oil can be recovered by about 100-150 tons.

2. Drilling mud material: In the exploration and development of oil fields and geological, water conservancy and coal exploration, it is used as an additive for drilling mud materials, which can improve the service life of drill bits, increase drilling speed and footage, reduce blockage when changing drills, and prevent wells from collapsing The effect is obvious. It can also be used as a fracturing fluid in oil fields and a water shutoff agent for profile control and water shutoff.

Packaging and storage of anionic polyacrylamide for oil drilling:

Oil drilling anionic polyacrylamide is packaged in three-in-one bags lined with film bags, each bag has a net weight of 25kg, and is stored in a cool, dry and ventilated place.

Oil drilling anionic polyacrylamide safety matters:

Avoid contact with eyes, skin and clothing, otherwise rinse with plenty of water.
