The Research And Application Of Drilling Fluid Lubricant LRH

Drilling fluid with liquid lubricant is an important chemical treating agent of drilling fluid, it can effectively improve drilling fluid lubrication, can reduce the friction between the tool and borehole wall, thus reducing rotating torque and the additional force, avoid sticking etc underground complicated accidents. In recent years, with the development of drilling technology, especially the large displacement Wells and ultra deep Wells and the development of offshore drilling technology, drilling fluid lubricant is becoming more and more important.Suitable for Liao he oilfield, the temperature of the liquid lubricant oil as the main raw material synthesis, indoor evaluation results show that the lubricant lubrication effect is remarkable, and has good resistance to salt, calcium resistance to high temperature resistance. 1- H11 Wells in Liao he oilfield Ann, 120-1 Wells and vertical Wells, horizontal Wells, field application results show that the indoor research and development of liquid lubricants LRH can effectively reduce the friction coefficient of drilling fluid, reducing load rig, improving drilling rate, maintain normal tripping and completion of assignments, and water-based drilling fluid compatibility is very good, can meet the needs of the different well type on drilling fluid lubricity.
