چکیده
اسیدکاری ماتریکس به یکی از دو فرایند تحریک چاه اشاره دارد که در آن اسید در منافذ سنگ، در فشارهای زیر فشار شکستگی نفوذ می‌کند. در طول اسیدکاری ماتریس، اسید، رسوبات و جامدات گل را در منافذی که مانعاز نفوذپذیری سنگ می‌شوند، حل می‌کند. این فرایند، منافذ طبیعی مخزن را به‌منظور جریان هیدروکربن‌ها تحریک می‌کند. در این مقاله ضمن بررسی سازوکار‌های مختلف فرایند اسیدکاری در مخازن کربناته و ماسه‌سنگی و ذکر واکنش‌های مربوطه، به بیان انواع دسته‌بندی‌ها در شبیه‌سازی‌ عددی اسیدکاری در مخازن کربناته شامل مدل لولهمویینگی، مدل شبکه و مدل پیوسته و نیز شبیه‌سازی اسیدکاری در مخازن ماسه‌سنگی پرداخته شدهاست. همچنین نحوۀ انجام مطالعات بهینه‌سازی عملیات اسیدکاری شرح داده شدهاست. در هریک از بخش‌ها نیز به بررسی مطالعات میدانی بر اساس نوع موضوع پرداخته شدهاست.

چکیده English

Matrix acidizing refers to one of the two well stimulation processes in which acid penetrates the rock pores at pressures below the fracturing pressure. During matrix acidizing, the acid dissolves sediments and mud solids which reduce the rock permeability. This process enlarges the natural pores of the reservoir that stimulates the flow of hydrocarbons. In this article, different mechanisms of acidizing process in carbonate and sandstone reservoirs and the relevant reactions are studied. Moreover, various simulation techniques of acidizing in carbonate reservoirs are studied, including the dimensionless model, capillary tube model, network model, and continuum model. Moreover, numerical silulation of sandstone acidizing is also discussed. Also, optimization of the acidizing process is described. In each of the sections, field studies have been investigated based on the type of subject.
