    1. Property
    One-way pressure sealant is made from natural fiber ,filling particles and additive.
    One-way Pressure Sealant is a product in the form of gray yellow powder, When used in drilling, it can effectively block up leakage of every kind from the formation under the action of one-way pressure difference. It also can improve mud cake quality and reduce water loss. It has very good compatibility and not affect the mud property .It is applicable for drilling fluids and completion fluids with different system and different density .
    The drilling fluid is DF-1 with a one-way pressure sealant, which is suitable for the porosity of different conditions in drilling and the seepage loss of micro-fracture formation. The good compatibility of the product is suitable for different system, different density of drilling fluid and completion fluid, the leakage of micro-cracks to achieve effective plugging, and can improve the quality of mud cake, reduce water loss. The recommended dosage for this product is 4%.
