Abstract

The invention discloses a single main pipe single well water distribution system applied to an oil exploitation field. The system mainly comprises a water injection station (2) connected with a water supply (1), a water injection main line (3) connected with the water injection station (2), and a water injection well (4) connected with the water injection main line (3). The invention further discloses a water distribution process based on the single main pipe single well water distribution system. According to the system, each well is provided with a water distribution chamber, and management is dispersed. But water injection branch pipes are short and are small in total quantity, so stratification testing is benefited, total investment can also be saved. The single main pipe single well water distribution system is suitable for an oil field which is multiple in the number of wells, adopts determinant to carry out well distribution, and is large in water injection quantity and area.

Description

technical field [0001] The invention relates to a single-pipe single-well water distribution system and a water distribution process applied in the field of petroleum exploitation. Background technique [0002] Water injection efficiency has always been one of the most common concerns in oilfield benefit analysis. my country has formed a relatively complete series of technologies and supporting technologies after decades of experience and practice in developing oilfields by water injection. The scale of water injection in the oil field is huge, and the power consumption of the water injection system is huge, which is a major energy consumer in the oil field. The water injection systems of major domestic oilfields generally have the problems of low efficiency, high energy consumption and serious energy waste. According to statistics, the power consumption of water injection accounts for 33% to 56% of the total electricity consumption of oilfields, and the energy consumption...
