[0002] Oil and gas field refers to the sum of oil reservoirs, gas reservoirs and oil and gas reservoirs within the same area controlled by a single local structural unit. If there is only an oil reservoir within this local structure, it is called an oil field; if there is only a gas reservoir, it is called a gas field. People usually refer to Daqing Oilfield, Shengli Oilfield and Sichuan Gasfield, which are mainly from the geographical sense or administrative units. In fact, they contain multiple oil fields or gas fields in the geological sense. In the strict sense of petroleum geology, it refers to a relatively independent and contiguous distribution of industrial oil and gas storage areas or geological bodies containing oil, gas and condensate gas. In exploration, it refers to a proven reserve trap; only oil and gas discoveries or only controlled and predicted reserves are generally referred to as oil and gas structures.
