Laboratory Research And Application On Environmental Drilling Fluid

With the development of drilling technology and people's awareness of environmental protection increases,new environmental protection drilling fluid has been paid more and more attention,for the study of environmental friendly drilling fluid is also enriched Glycoside drilling fluid is a new drilling fluid can biodegradable,not only to meet the various needs of drilling engineering,and have a great advantage in the aspects of environmental protection.This paper mainly expounds the glycosides as a kind of non-ionic surface active agent mechanism in glycoside drilling fluid system,and the chemical reaction equation.Optimization of different reagents glycoside drilling fluid system,and the overall performance analysis.In the aspect of environment effect for.And introduced the glycoside drilling fluid in the analysis of a portion of the well actual application and effect.Research shows that the glycoside drilling fluid system can reach the performance of normal drilling construction requirements,has the high temperature resistance and a good protective effect for low permeability reservoir,has a good inhibitory effect to water sensitive formation,And can achieve the anticipated effect for environmental protection.But At the same time glycoside drilling fluid also has some shortages,such as high cost of construction.
