| 摘 要： | 大牛地气田开发的中后期,气井出水严重,如果不能将其完全带出,则会在井底产生积液,产生的压力严重影响天然气产量和气田采收率。因此,通过确立符合本区块实际的临界流量的理论公式,预测气井井底积液的情况,可以指导气井的生产,提早通过泡排,换管柱,提产带液等措施防止生产井井底积液。并且指导以后新的开发井对管柱的合理选取,提高经济效益。这里在Turner及李闽等前人研究的基础上,通过与实际积液情况的对比,修正了理论公式,最后得到一个符合大牛地DK30井区盒2气层实际情况的计算临界流量的理论公式,经过验证,该公式能较为准确地判断积液情况。

| Abstract: | Production of gas field would be water flooded in the development of the mid-and late. If the droplets cannot be fully brought out, it will have fluid in the bottom. Pressure of the liquid loading causes serious impact on the natural gas production and gas recovery. Therefore by establishing a formula for the critical flow theory in accordance with the actuality of the block, we could predict the bottom wells of the fluid situation. Then through foam drainage, changing the pipe string and so on, we can prevent the liquid loading, guide the future development of new wells on the string of a reasonable selection, and increase economic efficiency. This article is based on the Turner, Min Li s researches, and amend the theoretical formula through the comparing theoretical liquid loading with the actual, Finally, we get a formula for the critical flow theory in accordance with the actuality of the Daniudi Gas Field. It can more accurately determine the liquid loading. |
