某海上油气田天然气处理流程适应性改造及其效果分析

Adaptive Transformation and Effect Analysis of Natural Gas Treatment Process in a Certain Offshore Oil and Gas Field

随着油气田的持续开发,油气井的产能不断发生变化,油气田的地面处理流程运行工况也必须随之变化。当油气井的产能达不到油气田地面处理流程运行工况要求时,需要对处理流程进行适应性改造,使其既能处理油气井所产物流,又能维持油气田的地面处理流程运转。以某海上油田为例,针对该油气田在气井降压生产后天然气处理流程无法满足透平及下游供气需求的状况,实施天然气处理流程适应性改造,并分析了改造效果,以期为其他油气田处理类似问题提供借鉴。

With the continuous development and production of oil and gas fields,the production capacity of oil and gas wells is constantly changing,and the operating conditions of surface treatment processes in oil and gas fields are also constantly changing.When the production capacity of an oil and gas well cannot meet the requirements of the surface treatment process operating conditions of the oil and gas field,it is necessary to adapt the treatment process to not only handle the logistics produced by the oil and gas well,but also maintain the operation of the surface treatment process of the oil and gas field.Taking a certain offshore oil field as an example,this article proposes an adaptive transformation of the natural gas treatment process in the oil field when the natural gas treatment process cannot meet the needs of the turbine and downstream gas supply after the gas well is depressurized and produced.The analysis and evaluation of the transformation effect provide relevant experience for other oil and gas fields in dealing with similar problems.
