| چکیده | ||
| از جمله روش‌های نو ظهور در افزایش بازیافت نفت، تزریق فوم به درون مخازن نفتی است. مهمترین محدودیت در استفاده از فوم در روش‌های بازیافت نفت، حفظ پایداری آن در مواجه با فاز نفتی است. در این پژوهش سعی شده است تا با ساخت بسترهای آزمایشگاهی، عوامل موثر بر پایداری فوم و ویسکوزیته ظاهری آن بررسی گردد. پایداری توده فوم، با اندازه‌گیری تغییر ارتفاع انواع فوم درون ستون عمودی مطالعه شده است. پایداری حباب‌های فوم با ساخت یک سلول هل‌شاو شفاف مجهز به سنسورهای فشار بررسی شده است. نتایج نشان می‌دهد که نوع ماده سورفاکتانت اثر قابل توجهی در پایداری حباب‌های فوم دارد. در ابتدا فوم‌های سدیم دودسیل سولفات و کوکامیدپروپیل هایدروکسی سولتین به ترتیب بیشترین پایداری را در حضور و عدم حضور نفت نشان دادند. اما با ترکیب 1:1 آن‌ها، پایداری فوم به میزان قابل ملاحظه‌ای افزایش یافت. نتایج مطالعات اثبات می‌کند فوم با بافت ریزتر، ویسکوزیته ظاهری بالاتری دارد. همچنین کیفیت فوم به‌طور مستقیم، و نرخ جریان فوم به‌طور معکوس بر ویسکوزیته ظاهری فوم تأثیر می‌گذارد؛ اما با افزایش نرخ جریان، وابستگی ویسکوزیته ظاهری به کیفیت فوم به شدت کاهش می‌یابد. | ||

| چکیده [English] | ||
| One of the methods to enhance oil recovery is the injection of foam into oil reservoirs. The most important restriction on the use of foam in enhancing oil recovery methods is maintaining its stability in the face of the oil phase. In this study, we tried to investigate the factors affecting the foam stability and its apparent viscosity by making laboratory setups. The stability of the bulk foam has been studied by measuring the height variation of the foam types within the vertical column. The stability of the foam bubbles has been investigated by making a transparent Hele-Shaw cell equipped with pressure sensors. The results show that the type of surfactant has a significant effect on the stability of the foam bubbles. Initially, sodium dodecyl sulfate and cocamido propyl hydroxyl sultaine foams showed the highest stability in the presence and absence of oil, respectively. But with the 1: 1 combination of them, the foam stability significantly increases. The results show that foam with a finer texture has a higher viscosity. Also, the quality of the foam directly, and the foam flow rate adversely, affect its apparent viscosity; however, as the foam flow rate increases, its dependence on foam quality is greatly reduced. | ||
