| Abstract: | Jialing 607-3-11 well is highly deviated,with high angle and big displacement.According to the formation characteristics,such as poor formation lithology and shale content,as well as big displacement well construction difficulties,through the optimization of drilling fluid technology to carry out the preparation and application of the inorganic gel and polymerization alcohol collapse prevention drilling fluid.Field application effect shows that the two kinds of drilling fluid performance is of stable,good rheological property,high mechanical drilling rate,strong carrying rock ability,environmental protection and lower toxicity,which effectively solve the wellbore stability,hole cleaning and anti-lubrication card,the three big technical difficult problems. |
