The invention discloses a single-main-pipe multi-well water distribution system for an oil field. The single-main-pipe multi-well water distribution system comprises a joint unit and a pipeline unit. The joint unit comprises a water injection station, a water distribution room, at least two water injection wells and pipeline joints. The pipeline unit comprises a water injection main pipe and water injection branch pipes. The water injection station is connected with the water injection wells through the water injection main pipe, and the water injection branch pipes are communicated to the water injection main pipe and are connected with the water injection wells through the water distribution room. The single-main-pipe multi-well water distribution system is flexible to use and beneficial for adjustment of an injection well pattern, and interference between the wells is small; the single-main-pipe multi-well water distribution system can be easily arranged in cooperation with an oil gas metering station and brings convenience to centralized heating, communication, management and control; the single-main-pipe multi-well water distribution system is strong in process adaptability and can be applied to oil fields developed through geometric well patterns basically.
Description
technical field [0001] The invention relates to a single dry pipe multi-well water distribution system used in oil fields. Background technique [0002] An oil field can be developed using only the natural energy of the reservoir, or it can be developed by maintaining pressure. The oil layer deeply buried in the ground has certain natural energy and pressure. During the development process, the pressure and natural energy of the oil layer will drive the oil flow to the bottom of the well and be lifted to the ground through the wellbore. During the flow and lifting process of underground crude oil, it is subject to resistances such as the fine pores of the oil layer, the weight of the liquid column in the wellbore, and the friction of the well wall. If oil is recovered only by natural energy, the process of oil recovery is a process in which both the pressure of the oil layer and the oil production rate gradually decrease. . When the oil layer pressure is greater than these...
