上游调峰对气田开发的影响

我国正处于天然气开发利用大发展初期，由于供气系统不完善，利用上游气田生产进行调峰比较普遍。从实际生产资料出发，论述了上游天然气生产与下游市场用气之间的矛盾以及利用上游气田生产进行调峰对气田开发所产生的影响，表现在：造成边底水入侵，生产能力下降；加速了地层能量消耗，缩短了稳产期，可采储量损失大；造成储层出砂，影响了气井正常生产。研究表明，在没有一定富余产能的情况下，利用上游气田生产调峰是不可取的，建议通过建设部分富余产能、地下储气库和引进LNG等多方式来满足调峰需求，以保证气田科学高效地开发。

The impact of peak regulation by enhancing gas deliverability on gas field development

At present, the exploitation and utilization of natural gas in China is at the initial stage of rapid development. Due to imperfections in the gas supply system, it is a usual practice to turn to high production of gas fields for peak regulation. Based on production logging data of some gas fields and the analysis of uneven gas demands associated with seasons and areas, this paper discusses the contradiction between the production of gas fields and gas demands, as well as the influences of peak regulation by utilizing the production of gas fields on gas field development. It shows that this situation will cause edge and bottom water invasion to reduce the production capacity, accelerate the consumption of formation energy, shorten the stable production period to bring a great loss to recoverable reserves, and result in sand influx to affect regular production in gas wells. Studies have shown that it is inadvisable to use the production of gas fields for peak regulation if there is not a certain quantity of surplus production capacity. It is suggested that surplus production capacity be constructed, underground gas storage be built and LNG be imported and so on to meet the demands of peak regulation and ensure scientific and effective development of gas fields.
