مدل‌سازی حرارتی یک بعدی رخنمون‌های سطحی، مثالی از کوه خامی و کوه میش

نوع مقاله: مقاله پژوهشی

چکیده

 
در این مطالعه از روش‌های مدل‌سازی حوضه رسوبی برای مدل‌سازی حرارتی رخنمون سطحی سازندها استفاده شده است. رخنمون سازندها در کوه خامی و کوه میش مورد مطالعه قرار گرفته و در سه محل، ویژگی سازندها مانند سنگ‌شناسی، ضخامت، شیب و امتداد لایه‌ها اندازه‌گیری شده است. با استفاده از داده‌های به‌دست آمده قسمت‌های فرسایش یافته، بازسازی شده و برشی از کوه خامی وکوه میش در امتداد شمال شرق- جنوب غرب تهیه شده است. این برش به صورت داده‌های عددی وارد نرم افزار مدل سازی شده و مدل حرارتی و تاریخچه پختگی سازند کژدمی و دیگر سازندها به‌دست آمده است.
 
این مطالعه نشان می‌دهد فرسایش، تاثیر زیادی بر میزان پختگی مواد آلی لایه‌ها در برش مورد مطالعه داشته است. فرسایش که منجر به کاهش عمق تدفین شده موجب پائین بودن دمای سازندها و کاهش نرخ واکنش‌های نفت زایی گردیده است.

A Linear Thermal Modeling of Surface Outcrops in Kuh-e Khami and Kuh-e Mish

چکیده [English]

In this study, a thermal modeling was carried out in surface outcropped-formations in Kuh-e Khami and Kuh-e Mish, Iran. The formations were studied by two sets of experiments obtained from three different locations. Lithology, thickness, dip and azimuth of strata were measured. Also the eroded parts of these formations were reconstructed. A cross section of Kuh-e Khami and Kuh-e Mish were prepared from NE-SW direction and was used for the simulation software. Finally maturity model and history of Kazhdumi were established based on the results. It was included that erosion had a significant impact on maturation rate of organic materials. Initiation of erosion from burial depth resulted in lower temperatures and oil production rates.
