低成本高低压注水工艺优化在海上采油平台的运用

Application of Low-cost High-low Pressure Water Injection Process Optimization in Offshore Oil Production Platform

某海上油气田应生产开发需求利用海水为介质通过注水泵增压对地层进行注水开发,随着开采时间的增长,地层能量不断消耗,油藏压力也不断地下降,地下原油大量脱气,黏度增加,油井产量大大减少。为了弥补原油采出后所造成的地下亏空,实现油田高产稳产,某油气田必须不断增加对地层的注水力度,油藏要求的注水量逐步超过了单台注水泵的设计处理量,本着降本增效的原则,对注水系统进行优化,解决注水瓶颈,提高注水效果。

An offshore oil and gas field should be used for production and development. Seawater should be used as a medium to inject water into the formation through injection pump pressurization. With the increase of mining time, the energy of the formation will continue to be consumed, the pressure of the reservoir will continue to decrease, and the underground crude oil will be degassed in large quantities. With the increase, well production is greatly reduced. In order to make up for the underground deficit caused by crude oil production and realize high production and stable production of oil fields, an oil and gas field must continuously increase the water injection intensity to the formation. The water injection required by the reservoir gradually exceeds the design throughput of a single injection pump, and the cost reduction The principle of efficiency enhancement is to optimize the water injection system, solve the water injection bottleneck, and improve the water injection effect.
