Organic Silicon in Petroleum Processing

1. Background of oil extraction

Oil is only the main energy in the world today, but also an important Strategic material. Oil resources products are directly related to economic development military strength.

The ultimate recoverable reserves of China's petroleum resources are approximately 13 billion to 15 billion tons, accounting for only about 3% of the world's total. The abundance value of China's petroleum recoverable resources (per unit land area) is about 57% of the world average, while the abundance value of remaining recoverable reserves is only 37% of the world average. In the past, the main oil fields in China were mostly distributed in the east.

At present, the oil fields in the eastern region have reached the late stage of oil recovery, most of them have implemented tertiary oil recovery measures such as water flooding polymer flooding; The newly developed oil fields in China are mainly distributed in the western region the coastal continental shelf. The new oil fields are far the main oil consumption markets, the production environment natural conditions of the new oil fields are harsh, adding many difficulties to the collection transportation of crude oil.

2. Petroleum additives

In the various processes of oil extraction extraction, it is necessary to apply various auxiliary agents to improve process conditions production efficiency. For example, the treatment of drilling fluid for oil production wells needs to be applied to viscosity reducing agents, filter loss reducing agents, flocculants, viscosity increasing agents, lubricants, emulsifiers, wetting agents, plugging agents; Drilling completion require the application of reservoir modification chemicals: production well plugging agents, acidizing agents, fracturing agents, etc.

Oil collection requires the application of oil extraction additives, such as chemical oil displacement agents, deep liquid flow directional agents, sand control agents, anti wax cleaning agents, anti scale descaling agents, etc; The collection transportation of crude oil require the application of demulsifiers, pour point depressants, drag reducing agents, etc; Petroleum refining requires the application of defoamers, scale inhibitors, etc; As a fuel oil, antiknock agents, synergists, etc. need to be added. The numerous petroleum additives mentioned above need to be applied to various chemical materials.

The proportion of crude oil with high wax content high solidification point in China's petroleum resources is relatively large. In the process of oil drilling transportation, especially in the transportation of crude oil pipelines, drag reducing agents pour point depressants are urgently needed. After adopting enhanced oil recovery measures such as water flooding in oil fields in eastern China, crude oil emulsification is severe, the collected oil flow has a heavy demulsification load. There is an urgent need for demulsifiers to promote oil-water separation, in order to reduce the water content in crude oil the oil content in the separated water.
