Cw Series of N0n-phosphorus Washing Liquid - Tianjin Kelioil Engineering Material and Technology Co., Ltd.

SUMMARY

l CW series of high-performance washing liquid has strong permeation function. It can quickly infiltrate the mud-cake generated by drilling work, then dissolve, disperse and remove the cake so as to significantly improve the displacement efficiency, prompt the casing and formation interface performance, strengthen the cementing slurry interface, and prevent leakage to a certain extent. CW, with excellent solubility and high-temperature stability, has strong ability to remove oil and very good activity in low temperature. It has very good compatibility with drilling mud and slurry and no adverse effect on drilling mud and slurry.

l CW series of high-performance washing-liquid include CW110L and CW210L.

l CW110L is a non-phosphorus compound, non-toxic and low-foam washing liquid.

l CW210L is a pure organic phosphorus, neutral, non-toxic and low-foam washing liquid.

l CW110L is mainly used for preparing the washing-liquid and spacer-liquid in well cementing that drilled with water-based mud; for oil-based mud with the same good results.

l CW210L is mainly used for preparing the washing-liquid and spacer-liquid in well cementing that drilled with oil-based mud; for water-based mud, it has same good results.

l CW110L,CW210L can be used alone, it is advised to be used together.

l CW110L,CW210L is only suitable for water-mixed, no special requirements for water quality. Fresh water of low salinity is suggested.

SPECIAL ATTENTIONS

CW110L and CW210L are not allowed to prepare washing-liquid with additive aqueous solution or high salinity water, or may lead to bad results because of compatibility.

CW110L,CW210L preparing washing-liquid should be tested in compatibility.

CW110,CW210L is almost suitable for all kinds of mud system and slurry system. Generally, the slurry should be insulated by appropriate amount of inert spacer-liquid, for example, fresh water or low salinity water, because CW110L has a certain reactivity resulting in slurry gel.

PHYSICAL AND CHEMICAL INDICATORS

CW110L can be packed with 5 UK gallon or 25kg plastic barrel. CW210L can be packed with 20kg,25kg or 5 UK gallon plastic barrel. they can also be packed according to users’ requirements.
