An oil field refers to the sum of oil and gas reservoirs within the same oil and gas production area under the control of a single geological structure (or stratum) factor. One oil and gas field may have oneOne or more reservoirs. The oil field is mainly the oil reservoir in the same area, and the gas field is mainly the gas reservoir. According to the geological factors in the area for controlling oil and gas production, oil and gas fields are divided into 3 types: constructing oil and gas fields. Meaning that the hydrocarbon production area is controlled by a single construction factor, such as wrinkles and faults. Secondly, the oil-bearing area of the stratum type oil and gas field is controlled by stratum factors (such as unconformity, pinch-out and lithology change of the stratum) on the background of a regional anticline or monoclinic structure. Compound oil and gas field. Oil and gas field with oil and gas producing area not controlled by single structure or stratum factor but controlled by multiple geological factors_。
