I. Product General
FA367 is a water soluble hi-molecule polymer from many organic anion, non-ion and other ion monomers. FA367 merges inhibition and fine infiltration into one and is used as tackifier and encapsulating agent in drilling fluid.

III. Function of Product
- The product can improve rheology of drilling fluid made up from FA367 has fine carrying performance and win best cleaning effect to well hole.
- Strong inhibition to mud shale.
- Fine heat stability in application of oil field with temperature resistance above 180℃.
- Fine salt-&calcium- resistant ability.
- It can effectively prevent oil-gas layer from polluting and increase output of oil and gas.
- It is suitable for all kinds of water-base drilling fluids, such as freshwater, seawater, staturated brine and so on with bigger adaptability.
- It has good compatibility with other treating agents.
IV. Application of Field
Application in 5000-odd wells in 16 oil fields in china shows that the drilling fluid system, which is made of zwitterionic FA367 and XY-27, can successfully apply to vertical, inclined, cluster, level, super deep and complex wells and all kinds of freshwater, brine, saturated brine, low-density and hi-density drilling fluid systems, not only can be used as drilling fluid but also as completion fluid, and can also stabilize well wall, protect production capacity of oil-gas layer, promote drilling speed and save drilling cost.
