Description

Description Lubricant for drilling fluid is a degradable lubricant. It is made of modified castor oil and span**0 as the major raw materials produced by reaction. As good lubricity, no fluorescence (low fluorescence), and various types of drilling fluid system (for example fresh water base drilling fluid and salt water base drilling fluid) compatibility, and is conductive to the geological logging, without prejudice well logging. It has been widely used in the oilfield, was well received by users. Application Lubricant for drilling fluid is recommended for reducing torque and drag in water base drilling fluid. It is compatible with both fresh water and salt water muds. Additionally, lubricant has an anti-foaming effect for drilling fluid. Recommended treatment Additions of 1.0% to 3.0% by volume of lubricant for drilling fluid, through the hopper, should provide optimum friction reduction. This product is mainly used to improve lubricity of drilling fluid and mud cake quality, reduce the rate of the lubricating coefficient and filter cake friction coefficient. It can be added uniformity in the mud according to the circulation time. Recommended dosage of it is about 1.5% to 3.0%. For deep drilling, lubricant should be added continuously to ensure that its minimum content is lower than 1.0% in the mud. Advantages Adsorption group of molecular chains can form a lubricating film on metal surfaces that resists removal and continues to provide lubrication. Packing Lubricant for drilling fluid belongs to a not-dangerous chemical and can be transported as normal chemicals. The product adopts the **0L blue drum packing, can also make to order a packing according to the customers. Transport storage process should be taken to prevent the damaged packing and inversion, to avoid over-exposure to the sunlight. The effective period is maintained for 2 years.
