Description
The dataset includes a combination of water flooding and gas injection enhanced oil recovery techniques. In China, the technological share for crude oil production is 80% water flooding and 20% gas injection, which represents the average production mix in China.
Water flooding technique: As an important method for enhancing oil recovery, water flooding involves injecting water or other fluids into the oil reservoir to increase formation pressure and drive crude oil toward production wells.
Gas injection technique: A reservoir engineering process used to improve crude oil recovery by injecting a working agent (natural gas or air) into the reservoir through injection wells, thereby displacing residue oil into surrounding production wells. Low-permeability oilfields are oilfields characterized by low reservoir permeability, low abundance, and low single-well productivity. The net calorific value of crude oil is 43.4 MJ/kg, and the average calorific value of natural gas is 36 MJ/Sm³.
Activity Description
This dataset represents offshore extraction of oil and gas from low-permeability oilfields using a combination of water injection and gas injection techniques. The process includes oil production and surface processing stages. The oil production stage involves lifting oil and gas to the surface using pumping units to bring crude oil and natural gas from underground to the surface. Surface processing mainly includes three-phase separation of oil, gas, and water, as well as transportation of oil and gas.
Process Description
Crude oil (non-heavy oil) is a fossil fuel with a net calorific value of 43.4 MJ/kg. The density of crude oil varies depending on the characteristics of the oil field, and its relative density generally ranges between 0.75 and 0.95 g/cm³. Crude oil is primarily produced through underground extraction. It is mainly used as a feedstock in refineries for the production of various fuels and petrochemical products.
