Ⅰ. EOR PRODUCTS
When oil fields are in EOR periods, feeding a ton of polymer can increase the production of crude oil by 120 ~ 150 tons for users.By injecting polymer solution with suitable viscosity,it can improve the sweep efficiency of injected fluid,and thus block big channels.Our products have already been widely used in oilfields like in Daqing, Shengli, Dagang, Liaohe, Xinjiang, Henan, North America, South America, India, the Middle East, Russia and other fields.
Ordinary product can resist a temperature up to 75℃ and a salinity up to 30000 ppm. Salt-tolerant products can resist a temperature up to 90℃ and a salinity up to 30000 ppm.

Ⅱ.PROFILE MODIFYING/WATER SHUTOFF AGENT
Profile modifying/water shutoff agent works through feeding crosslinking agent to polyacrylamide solution with certain concentration,then high-valence metal ions within the crosslinking agent combine with carboxyl groups from polyacrylamide in the form of multi-core hydroxyl bridge poly ion. Specific reaction equation is as follow (M represents high-valence metal ions) :

Ⅲ.DRILLING FLUID PAM
Drilling fluid PAM can effectively improve the performance of drilling fluid and prevent borehole from collapsing.Also,it can cool down and lubricate the drill bit.Drilling fluid PAM is appliable to low solid non-dispersed polymer drilling fluid system and can be mix-used with various treatment agent.Also,it is suitable for all kinds of mud system. Product features:
a, Shale inhibitor: inhibit clay mine contained in shale from hydration, expansion, decomposition, and prevent the borehole from collapsing.
b, Filtration reduction:reduce the amount of water entered into the layer,the hydration expansion of mud shale.
c, Viscosity reduction:collect at the edge of the protected clay particles and enhance its negative effect to prevent the system from forming space truss structure , thus have the effect of reducing viscosity.

Ⅳ.FRACTURING FLUID PAM
For oil reservoirs with low permeability,cracks are made by fracturing the layer with pressure.Prop it up with proppant to reduce the flow resistance to increase yield.After crosslinking,fracturing fluid viscosifier can transfer high levels of proppant into cracks.This product has good performances on shear resistance and thermal stability.

Usage and dosage:
a, Preflush acid: 0.8-1.5 m3 / m reservoir
b,. Main processing acid: 1.2-2 m3/m reservoir (experiments are needed firstly to determine the blocked pollution radius, then calculate from v = 3.14 h (Ri2 - rw2)
c, After-displacement fluid: 0.8 to 1.2 times as much as the main processing fluid.
Ⅴ.DRAG REDUCTION AGENT PAM
Drag reduction agent PAM is widely used in pipeline of crude oil and product oil. Fluid flow in the pipeline will be restrained with frictional drag of fluid,which results in the decreasing of the amount of pipeline transportation and the increasing of energy consumption.The use of drag reduction agent is an important method to improve flow capacity of pipeline and reduce energy consumption in a certain area. Our product can effectively reduce the flow resistance and inhibit the corrosion of pipeline.

Usage: Sprinkle this drag reduction agent into a small amount of water and stir to make sure it is evenly dissolved.Then gradually inject the prepared solution into the pipe and mix with substances in pipes. Do not inject at a speed too fast, otherwise it will cause the flow gradient.
Dosage: 3 kg/m3 liquid. |
