چکیده

پسماند مایع یکی از مشکلات رایج در چاه‌های گازی است که می‌توانند سبب توقف تولید گردد. این پژوهش سعی کرده وقوع این پدیده را در یکی از میادین گاز میعانی خشکی ایران با استفاده از نرم‌افزار پاپیسیم بررسی کند. در این پژوهش تشکیل مایعات در مخزن گازی در میدان مورد نظر و رفتار این پدیده در طول تولید از چاه و روش‌های کنترل آن مورد مطالعه قرار گرفته است. نتایج این پژوهش نشان دهنده رخداد پسماند مایع در چاه به علت افشار در مخزن به اندازه ۲۲۰۰ پام می‌باشد، سپس نرخ بحرانی پسماند مایع مقدار ۲/۶ میلیون فوت مکعب توسط نرم‌افزار پایپسیم محاسبه شد و راهکارهای مناسب برای کنترل تولید از چاه و پسماند مایع با استفاده از تغییر قطر لوله و همچنین استفاده از کاهنده جریانی بررسی شد که نشان دهنده این بود که استفاده از کاهنده و لوله با قطر مناسب می‌تواند تأثیر مناسبی بر کنترل تولید بگذارد.

چکیده [English]

Liquid Loading is one of the common problems in gas wells that can cause production to stop. This research has tried to investigate the occurrence of this phenomenon in one of Iran’s onshore condensate gas fields using PIPESIM software. In this research, the formation of liquids in the gas reservoir in the target field and the behavior of this phenomenon during production from the well and its control methods have been studied. The results of this research show the occurrence of liquid Loading in the well due to overflow in the reservoir of 2200 psi, then the critical rate of liquid loading of 6.2 million cubic feet was calculated by Pipesim software and the appropriate solutions to control the production from the well and LL It was checked by changing the diameter of the tubing and also using a choke, which showed that the use of a reducer and tubing with the right diameter can have a good effect on production control.
