The product is manufactured by special processing treatment of several surfactants and cationic shale inhibition agent as well as asphalt with specific range of softening point. The micron-grade asphalt particles with positive electron are easily attached with solid particles with negative electron, together participating in the forming of mud cake, to improve quality of mud cake. The micron particles and cationic shale inhibition agent can penetrate into bore fracture to create absorption as well as convergence, playing the function of plugging, bridging and anti-swelling, preventing collapse, reducing water loss as well as protecting oil/gas zone.
The product is suitable for all water based drilling fluid system. The product is applicable for all types of development wells, excluding exploration wells.
USE AND DOSAGE:
It can be evenly and directly added into circulating mud, with recommended volume of 1.0-2.0% of circulating mud.
- Each barrel must be used up just for one time and it is better added from weight pump or mud tank. It is not allowed to pour into earth pit or pumped by gear pump or submarine pump, otherwise, the pump body gets easily plugged.
- If gear pump or submarine pump is used to pump the asphalt from package barrel, it needs to fill a little water into pump before pumping asphalt. After loading asphalt, clean pump with water so as to avoid attachment on the pump or pipeline.
- After a long time of storage, there will be crust (about 1 cm thickness)on the top of package barrel, which is a normal phenomenon, and can be evenly mixed by rolling or blending.
PACKAGING AND STORAGE:
It is packed in Polyethylene plastic barrel, net weight 50kg/barrel. Iron barrel can be used for long transportation, net weight 200 kg/barrel. It is stored in dry place with good ventilation. Quality guarantee period: 1 year.
Avoid contact with eyes, skin and clothing, or wash with plenty of water.
