Shaanxi Wand Petroleum introduces the oil extraction processes as follows

Shaanxi Wand Petroleum introduces the oil extraction processes as follows:

1. Drilling process: Using drilling equipment to drill a wellbore underground to obtain the initial completion of the oil well.
2. Cementing process: Cementing inside the oil wellbore to stabilize the wellbore, prevent the intrusion of groundwater and underground gases, and ensure the safety of oil extraction.
3. Wellbore completion process: Installing pipes inside the oil wellbore through completion equipment to form the wellbore.
4. Hydraulic fracturing process: Injecting high-pressure liquid to expand the fractures in the oil layer, improve the permeability of the oil layer, and increase the production capacity of the oil well.
5. Water injection process: Injecting water into the oil well to increase the internal pressure of the oil well, push the crude oil towards the wellhead, and increase the efficiency of oil extraction.
6. Wastewater treatment process: Treating the wastewater produced by the oil well that contains impurities to purify the wastewater and recover valuable substances.
7. Well abandonment process: After the oil well has completed production, closing the well through processes such as dismantling and plugging.
8. Purification process: Extracting pure petroleum products from the extracted crude oil through processes such as separation, dehydration, and desalination.
9. Storage and transportation process: Storing and transporting the purified petroleum products to ensure the quality and supply of petroleum products.

The above are some common oil extraction processes shared by Shaanxi Wand Petroleum. The specific processes may vary depending on the geological conditions and extraction methods of the oilfield.
