چکیده

سیالات تکمیل چاه برای تکمیل و تعمیر موفقیت‌آمیز چاه‌های نفت و گاز، به‌ویژه در مخازن چالش برانگیز با دما، فشار بالا و نفوذپذیری پایین ضروری هستند. هدف اصلی این مطالعه به بررسی و ارزیابی آسیب سازند دو سیال مجرابند جدید، یکی پایه فسفاتی و یکی پایه نیتراتی می‌باشد. در این پژوهش دو سیال تکمیل با چگالی بالا مورد استفاده قرار گرفته است. اولین سیال، سیال پایه فسفاتی با چگالی pcf 114 و بعدی سیال پایه نیتراتی است که با افزودن حل‌کننده به چگالی بیشتر از pcf 95 رسیده است. در این مطالعه آزمایش‌های آسیب سازندی هم‌چون تغییر ترشوندگی، تورم رس، سازگاری سیال مجرابند با سیالات مخزن و نفوذ سیال به پلاگ (سیلاب‌زنی) انجام شده است. نتایج تجربی نشان می‌دهد که ارزیابی‌های سازگاری سیالات عدم وجود امولسیون با نفت خام و میعانات را برای همه سیالات نشان می‌دهد، اما در ارزیابی مربوط به سازگاری آب سازند در سیال پایه فسفاتی مقدار رسوبات جزئی مشاهده شد. نتایج آزمایش نفوذ سیال به پلاگ کربناته و ماسه‌سنگی برای سیال پایه فسفاتی نشان می‌دهد که این سیال می‌تواند به‌ترتیب 17/41% و 5/30% و نتایج آزمایش نفوذ سیال به پلاگ کربناته برای سیال پایه نیتراتی نشان می‌دهد که این سیال می‌تواند 33/29% تراوایی سازند را کاهش دهد که این میزان آسیب سازند به‌طور قابل توجهی کمتر از سایر سیالات مانند گل حفاری می‌باشد. همچنین نتایج حاصل از آزمایش تورم رس نشان می‌دهد که میزان تورم رس ناشی از هر دو سیال کمتر از mL 5 در g 2 رس می‌باشد. از این‌رو این سیالات می‌توانند به‌عنوان سیال مجرابند در چاه‌های نفت و گاز استفاده شوند و بهره وری و ایمنی را به ویژه در مخازن چالش برانگیز با دما و فشار بالا و نفوذپذیری کم افزایش دهند.

چکیده [English]

Well completion fluids are crucial for the successful completion and workover of oil and gas wells, particularly in challenging reservoirs characterized by high temperatures, high pressures, and low permeability. The primary objective of this study is to investigate and evaluate the formation damage inflicted by two novel packer fluids: one phosphate-based and the other nitrate-based. In this research, two high-density completion fluids have been used. The first fluid is the phosphate based fluid with a density of 114 pcf and the next fluid is the nitrate based fluid, which has reached a density greater than 95 pcf by the addition of solvents. This research has conducted various formation damage tests, including assessments of wettability alteration, clay swelling, compatibility of the packer fluid with reservoir fluids, and fluid invasion into the plug (coreflood). The experimental results reveal that compatibility assessments of the fluids indicate no emulsion formation with crude oil and condensates for all fluids tested. However, in the evaluation of formation water compatibility with the phosphate-based fluid, a minor amount of precipitation was observed. Fluid invasion tests into carbonate and sandstone plugs for the phosphate-based fluid demonstrate that this fluid can cause 41.17% and 30.5% reduction in formation permeability, respectively. In contrast, fluid invasion tests into carbonate plugs for the nitrate-based fluid show that this fluid can cause 29.33% reduction in formation permeability, which is significantly less than that caused by other fluids such as drilling mud. Furthermore, the results from the clay swelling tests indicate that the clay swelling caused by both fluids is less than 5 milliliters per 2 grams of clay. Consequently, these fluids can be effectively employed as packer fluids in oil and gas wells, enhancing operational efficiency and safety, particularly in challenging reservoir conditions characterized by high temperatures, high pressures, and low permeability.
