How to do add antifoam in Oil ?

1. Oil extraction

 Foaming material: drilling fluid;

Foaming mechanism:

(1)Formation gas: When drilling into a gas-bearing formation, the hydrocarbons, CO2, H2S and other gases in the formation are easy to diffuse or invade the drilling fluid.

(2)The treatment agent decomposes to generate gas.

(3)Air: When drilling fluid circulates through the ground, it is easy to introduce air from vibrating screens, mixers, mud pumps, etc.

(4)Surfactant: sometimes to stabilize the pH of the drilling fluid and improve the thermal stability of the drilling fluid, it is also necessary to directly add sodium alkyl sulfonate (AS), sodium alkyl benzene sulfonate (ABS), polyoxyethylene octyl Surfactants with strong foaming properties such as phenol ether

n-site environment: the temperature can reach 200℃; gas-liquid mixing.

Addition point of defoamer: According to customer's usage habits, some are added to drilling aids, and some are added directly on site

2. Cementing section

 Foaming substance: cement slurry

1.Foaming mechanism: related to various factors such as the composition of admixtures, the salinity of water, the gasification of cement and the mixing of cement injection equipment

2.If the cement slurry contains lignosulfonate admixture, the high plasma concentration of Ca2+, Mg2+ and Cl- in the water can easily induce bubbles in the cement slurry. In order to better operate

3.On-site environment: high shear of cement mixing, up to 12000rpm.
