Drilling fluid system name

Polymeric alcohol drilling fluid system

Matching core finishing agent

Polymeric alcohol JLX-A    Polymeric alcohol JLX-B    Polymeric alcohol JLX-C

System characteristics

1、Improving the rheology of drilling fluid and increasing the solid phase capacity limit by 10~20%;

2、Improving the heat stabilizer of organic treatment agent, while improving the temperature resistance of the treatment agent 20~30 ° C;

3、Strong anti sloughing capacity and caliper rule, while the average hole expansion rate is ≤ 5%;

4、The wellbore mud cake has the property that is  similar to oil based drilling fluid and it has excellent lubricity;

5、Increasing the viscosity of filtrate, block the molecular glue and reducing the oil-water interfacial tension, while protect the reservoir;

6、Preventing the bit mud packs, reduce the complex accidents downhole and increase the rate of penetration;

7、LC50>30000mg/L, while protect the environment.

Application situation

Thousands of vertical wells, large deviated wells and horizontal wells have been used in the exploration and development of China National Offshore Oil Corporation, China National Petroleum Corporation, Sinopec General Corporation and Phillips and Apache oil companies on abroad, while the field application shows that the drilling fluid rheology is easy to adjust, wellbore stability and wellbore regularity, which increase mechanical drilling rate and oil well production, also it has protected the ecological environment, and achieved obvious economic and social benefits.
