液量大幅度变动是集油站分离器和缓冲罐在生产中出现的普遍现象,其原因有:①设备预留的处理能力大。对于注水开发的油田,没备设计处理量至少为建站时液量的2倍;②因投产时局部进油,或开发数据不准,集油站投产初期,液量低于预计处理量;③生产中开关井或减产使液量不稳定;④油井出油波动和集输管道中气液塞造成的液量瞬时波动。所有这些因素,使初期最小液量往往达不到设计最
The drastic change of liquid volume is a common phenomenon occurred in the production of petrol station separators and buffer tanks. The reasons are as follows: ① The equipment has large processing capacity. For the oilfields developed by waterflooding, the designed treatment capacity is at least 2 times of that of the built-up stations; ②The oil volume is lower than the expected treatment volume at the initial stage of the start-up of the oil gathering station due to the local oil inflow or the development data are not allowed due to the in-production, The production of switching wells or cut to make the liquid volume instability; ④ Oil outflow fluctuations and gas gathering pipeline plume caused by the instantaneous fluctuations in liquid volume. All of these factors make the initial minimum volume often fail to design the most
