Introduction:

It is produced by esterification and sulfonation of octanol, maleic anhydride and other raw materials. It is an anionic surfactant. It is the main assistant in mud releasing agent. It has good permeability, can greatly reduce the surface tension, can reduce the contact angle between the releasing fluid and the drilling tool, enhance the lubricating ability, and has low fluorescence. It can be used in the exploration well fresh water mud and normal pressure area. The product has certain anti collapse effect. It is the main assistant in mud releasing agent. It is nontoxic, does not pollute the environment, and low fluorescence does not affect logging. In addition, fast t also has a certain lubricating effect, which can reduce the wear of drill bit and other accessories, reduce the torque, and extend the service life.

Structure: sodium isooctyl maleate sulfonate

Stability: not resistant to strong acid and alkali; not resistant to heavy metal salts and reducing agents.

Performance:

The permeability is fast and uniform, the re wettability, emulsification and foaming are all good. The temperature of its use effect is below 40 ℃, and the pH value is between 5-10, which is the best. However, once treated with penetrant T, the permeability can not be affected by the change of temperature, acid and alkali, and it is easily soluble in hydrophilic solvent; it can also be soluble in benzene, kerosene, petroleum solvent, etc.

Project indicators:

Appearance: colorless to yellow viscous liquid

The permeability is 120s (0.1% aqueous solution), small cracks appear within 60 seconds of mud cake penetration, and many cracks appear within 180 seconds

Capillary effect: 9-10cm / min

Settlement performance: 5S

Ionic property: anion

Solubility: soluble in water, milky white solution,

Diffusion performance: 5S

Usage and dosage:

It is mainly used for drilling and releasing stuck. In case of stuck drilling in the process of drilling production, inject the agent into the location of stuck point, soak for 2-4 hours, and lift up and lower the movable drilling tool to release the stuck. The dosage depends on the specific situation of the site. When penetrant t is used

If there is too much foam, a small amount of defoamer GP or octyl alcohol and three butyl phosphate can be added.

Package and Storage:

Metal pail, 200Kg/drum or plastic drum, 50Kg/drum.
