Products Description
Polyacrylamide, is solid powder water-soluble polymer with varying molecular weight and charge density. It is most often used to increase the viscosity of water or to encourage flocculation of particles present in water and allow rapid settlement of finely suspended solids. It is a synthetic chemical that can be tailored to fit a broad range of applications.
The flocculation effect of oilfield chemical treatment agent polyacrylamide PAM in the drilling process is a major user of polyacrylamide in the petroleum industry. The oilfield chemical treatment agent polyacrylamide PAM has been applied in the fields of tertiary oil recovery, drilling, water plugging and profile control.
The technological progress of polypropylene polymers has accelerated the development of the petroleum industry, and the demand of the petroleum industry has accelerated the technological innovation and development of polyacrylamide PAM. Polyacrylamide, as a drilling fluid, only began to be applied in drilling in the mid-20th century, causing significant changes in the development of drilling fluid. It not only improved drilling speed, but also led to the development of drilling fluid types from natural polymers to synthetic ones, and brought drilling fluid technology into a scientific development stage.
In drilling fluids, it can be used as the daling mud performance modifier in the drilling process. The role of polyacrylamide is to improve the rheology of the driling fluid, carry rock debris, lubricate the drill bit, and increase he rate of penetration. In addition, it can greatly reduce sticking accidents, reduce equipment wear, prevent well blowouts and borehole collapse, and avoid formation damage during dulling.
The important role of polyacrylamide in oilfield drilling is its flocculation, and the solid phase in the drilling fluid is one of the key factors affecting the cost and speed of the drilling fluid. In the late 1960s, polymer flocculants were introduced into drilling fluids abroad, and high-quality non dispersed low solid polymer drilling fluids were applied, resulting in a significant increase in drilling fluid speed and becoming one of the four important technologies in the contemporary drilling industry.
Polymer flocculants can keep drilling cuttings and inferior soil in a non dispersed flocculation state in drilling fluid, which can be removed by mechanical solid control equipment. This effectively solves the problem of dispersion and accumulation of drilling cuttings in dispersed drilling fluid systems, not only accelerating mechanical drilling speed, but also reducing many complex situations during the drilling process, effectively protecting oil and gas reservoirs and reducing drilling logs.
The polyacrylamide flocculants used in drilling fluids include non hydrolyzed polyacrylamide and hydrolyzed polyenediamine. Hydrolyzed polyacrylamide is a selective flocculant, while non hydrolyzed polyacrylamide is a full flocculant. The molecules of non hydrolyzed polyacrylamide only have polar amide groups, which do not carry negative charges. The hydration film is thin, and the repulsion force between them and inferior and high-quality soil is relatively small. When encountering these two types of particles, bridging and adsorption can occur; Hydrolyzed polyacrylamide flocculant not only flocculates drilling cuttings in drilling fluid, but also high-quality soil in drilling fluid, playing a role in total flocculation. When hydrolyzed polyacrylamide reaches a certain degree of hydrolysis, it carries a relatively high negative charge density and also has a thicker hydration film.
When approaching high-quality soil particles, there is a large electrostatic repulsion force and a hydration film repulsion force between them, making it difficult to adsorb high-quality soil particles; When it is close to the drilling cuttings, it is easy to generate adsorption, forming flocculent agglomerates, which are removed from the drilling fluid and play a selective flocculation role.
