Petroleum Products Gas Field Drilling Lignite Resin

Advantages

Not only we are the first and now the largest manufacturer of sulfonated asphalt here in China, but also we have always been focusing on the producing and researching of oilfield chemicals since the very beginning of our establishment, and are playing an important role in both domestic and international market.

Our production capacity keeps improving, until 2011, our annual capacity reached 15,000 MT, which placed us in the very first place compared with others.

Our products are exported to overseas, such Saudi Aramco, Baker Hughes, Halliburton etc, so it enjoys high reputation in the world.

Our products are 100% qualified before shipments.

Introduction

Hot Products Gas Field Drilling Lignite Resin is a kind of drilling fluid filtration reducer composed by sulfonated phenol-formaldehyde resin and sulfonated lignite, and can be used together with sulfonated asphalt, sulfonated tannin etc.

Being heat and salt resistant at the same time, it is one of the ideal products for high temperature and deep well mud systems.

Application

Hot Products Gas Field Drilling Lignite Resin is a kind of copolymer contains hydroxyl, carbonyl, methyl, sulfonic acid base, nitriles and some other functional groups, and is made by grafting copolymerization and sulfonation.

The main function is to reduce filtration loss, but it can also reduce viscosity at the same time.

It is heat-resistant because it draws sulfonic group into benzene ring unit, and the benzene ring is linked with carbon atoms.

Owing to the introducing of sodium sulfonate SO3NA in benzene hydroxyl, it strengthens the hydration, which thus results in fine solubility.

As a deep well mud treatment, Resinated Lignite owns the characteristics of reducing HTHP fluid loss, salt-resistant, calcium-resistant etc, and plays a great role in consolidating well wall, preventing collapsing and stucking.

Company profile

Henan Xinxiang No.7 Chemical Co., Ltd is specialized in manufacturing oil field drilling fluid additives. We are the first and now the largest manufacturer of sulfonated asphalt here in China.

We began to research and develop the production of sulfonated asphalt in 1983, and in 1985, our sulfonated asphalt was firstly sold to oil filed to solve complicated drilling problems, such as anti-collapsing, fluid loss reducing etc.

We will keep doing our best to meet each customer’s requirements, providing you good quality products at competitive prices.
