Chinafloc has supplied products to the Chinese oilfields for over 10 years and today is the leading supplier of polymers to this industry.All the major Chinese oilfields including Daqing,Shengli,Xinjiang,Dagang and Huabei use our products extensively.Over recent years companies overseas have commenced using our polymers in the oilfields.

Enhanced Oil Recovery

This process has been used for several years in assisting the operator to increase the efficiency of oil recovery of tertiary floods. In tertiary oil recovery technologies, chemical flooding is a very important tertiary oil recovery technology. Chemical flooding includes polymer flooding, ASP flooding, Colloidal Dispersion Gels flooding and so on.

Polymer flooding is applied to:

● Control the mobility ratio of the water injection and the general mobility ratio of high water containing stratums

● Adjust the water absorption of high and low water containing stratums

● Increase the water content of low penetrating oil stratum

● Expand the swept volume of water injection

● Decrease the water content in the oilfield

● Enhance the oil recovery rate of the oilfield.

By the addition of one tonne of polymer typically 120~150 tonnes of crude oil can be gained therefore providing great benefits to the user.

If the temperature of polymer flooding is lower than 85℃ polymer flooding treatment is relatively simple.With temperatures up to 95℃,then polymer-flooding techniques can be still applied.

Drilling Mud Additives

 

The CHINAFLOC range of products has been used successfully for many years as drilling mud additives for viscosity modification,shale inhibition/clay stabilization and fluid loss control. A comprehensive range is available so that optimum performance can be achieved to suit the particular type of water based drilling mud system used by the operator.

Viscosity Modification.

Typically polymers or PHPA's are used on their own or in conjunction with bentonite,as extenders,increasing the drilling mud viscosity thereby resulting in improvements in the removal of cuttings,better control of mud densities and lubrication of the drill bit.Additionally,during downtime,due to the thixotropic nature of the drilling mud system the cuttings will be held in suspension thereby not causing any major problems with solids settlement.
