تعتبر الدراسة المخزونية لطبقات الأرض العماد الرئيسي في تحديد الاحتياطي الجيولوجي
و في تحديد مواصفات الطبقة الخزنية, و قد استخدم في ذلك عدد من التقنيات و سوف
نهتم في هذا البحث بدراسة تطبيقات تقنية DCA في حساب المواصفات الخزنية من
خلال توظيف معادلة موازنة المادة في برامج النمذجة و المحاكاة من أجل تقدير
الاحتياطي الجيولوجي, حيث تعتمد هذه التقنية على تحليل انخفاض الإنتاج الذي هو
تحليل المعطيات السابقة لتراجع أدائية الإنتاج و التي يعبر عنها باللوحات البيانية التي
تربط ما بين معدل الإنتاج و الزمن, أو معدل الإنتاج و الإنتاجية التراكمية. و ذلك لكل من
. الآبار و المكامن, و سنأخذ في بحثنا هذا هذه المنحنيات من عام 1975 حتى عام 2005
و سوف نخص بالبحث أحد حقول شركة الفرات (حقل التيم-تشكيلة الرطبة) آملين أن
تحقق هذه الدراسة المتواضعة الهدف المرجو منها.
In this study, we study the applications of DCA technology to
calculate the specifications of the reservoir by using the equation of
the material balance in the modeling and simulation programs in
order to estimate Geological reserve. This technique is based on the
analysis of the decline in production, which is the analysis of the
previous data of the decline in production performance, which is
expressed in the graphs that link the rate of production and time, or
the rate of production and cumulative productivity. For each of the
wells and reservoirs, and we will take in this research these curves
from 1975 to 2005. We will specialize in research one of the fields of
the Euphrates (Thayyem field– Alrutbah formation) hoping that this
modest study will achieve the desired goal.
