Environmental protection type lubricant used in drilling fluids

1. Product introduction

Extreme pressure lubricant produced by our company is an environmental protection  type of drilling fluid lubricant which is composed of a natural vegetable oil and other raw materials by the high temperature synthesis. It is a brown oily liquid. This product has changed the traditional lubricant performance, make it have excellent extreme pressure lubricity and extreme pressure film strength under high pressure in the deep well, on the basis of satisfying the lubrication in the card. It not only has the prominent effect that lubrication and anti-seize in the high angle hole and bad ground, but also has good compatibility with drilling fluids, does not pollute the environment, does not disturb exploration well and fluorescence well logging quality, etc. It is suitable for all kinds of water-based and oil-based drilling fluid systems, can effectively reduce torque and friction resistance of drilling tools, inhibit clay shale hydration and stabilize the borehole wall. This product has obtained national patent.

2. Action mechanism

Outstanding performance of lubricants used in drilling fluids is that solid - solid friction between drill string and borehole wall rock is turned into the friction between nonpolar sides or between oil film by adsorption film which polar bond of product form on the surface of metal, rock and clay. It will reduce greatly friction resistance between the rotary drill string and the rock. At the same time, under the condition of high temperature and high pressure, a solid chemical film will be formed on the metal surface to reduce friction of the metal contact interface to take lubrication effect.
