Multifunctional Drilling Fluid Additive

1. Introduction

After many years' researches, our company has developed the multifunctional DZJ ,which has the function of heat, salt and calcium resistance, reducing the filtration loss, collapse resistance, lubricating and protecting the oil and gas reservoir and has no pollution. This product can be used to improve the mud rheology, increase the sand-carrying capacity, regularize the well diameter and protect the well wall. As a result, the drilling will be easier, the drilling speed and efficiency will be increased. Besides, this product has wide application range, especially suitable for resolving the collapse, lost circulation and lubrication problem. It is suitable for deep well, super-deep well, fresh water, salt water and saturated salt water. With this product, other products cannot be used.

This product has great filtration loss effect and has the function of collapse resistance, lubrication and protecting the oil and gas reservoir. Besides, it can adjust the mud rheology and regularize the well diameter to make the mud cake thin and tough. As a result, the drilling speed and period are shortened. The multifunctional drilling fluid additive has great compatibility and can be used together with any other products.
