Oilfield drilling additives

Oilfield drilling additives            Petroleum additives

There are mainly two types of additives used in oil drilling: ① oil well cement additives, which block cement. Their function is to properly effectively reinforce the various excavation channels of the oil well, in order to achieve the purpose of sealing off the bottom oil gas, preventing water layers affecting oil pipelines, thus forming a closed efficient mining environment. the current situation of oil extraction in China, the development of such additives is mainly based on sulfonic acid polymers, which are commonly used effective additives. They have characteristics such as high temperature resistance, waterproofing, environmental protection. In application, they can significantly improve the oil field recovery rate, thereby making pipelines operate more stably. Commonly used include dispersants, fluid loss agents, etc.; ② Drilling fluid treatment agent is a new type of plugging product, with high temperature resistance, cleanliness, strong plasticity as its main development direction. This product is becoming increasingly mature in research in China, some products have been industrialized, with broad market prospects considerable economic benefits in practical applications.

1.2 Additives for crude oil extraction

There are three commonly used additives in crude oil extraction: ① Water blocking agents, mainly used to reduce the impact of water on oilfield production. Increasing water content will reduce the quality of crude oil directly affect the economic benefits of the entire oilfield production. The scientific reasonable application of water blocking agents can reduce the impact of water on oilfield development, improve the efficiency quality of crude oil extraction; ② Fungicides, which are oilfield additives that ensure the quality of crude oil, are widely used in the basic process of crude oil extraction, that is, in oilfield development transportation; ③ Acidic corrosion inhibitors are a serious problem that occurs in oil field exploitation, which can cause damage to mining equipment, thereby affecting mining efficiency progress, causing economic losses for oil mining enterprises. The application of acid corrosion inhibitors can reduce the acid corrosion of mining equipment, reduce mining costs, improve economic benefits. Imidazoline polyoxyethylene ether is commonly used, which can effectively reduce the acid corrosion in oil production improve the service life of metal instruments.

1.3 Additives for oil gas transportation

As the name suggests, additives for oil gas transportation are oilfield additives used in the process of oil gas transportation. Their function is to ensure that crude oil does condense during transportation, to maintain smooth flow during both the injection output of crude oil, ensuring transportation efficiency. Its main components are viscosity reducing agents drag reducing agents. The former can effectively ensure the quality of crude oil transportation, while the latter can ensure smooth flow of crude oil to improve transportation efficiency
