چکیده

سازند آسماری به سن الیگومیوسن یکی از مهم­ترین مخازن هیدروکربوری در خاورمیانه است. برای شناخت ویژگی­های بیواستراتیگرافی، انواع رخساره­ها و محیط­های رسوبی دو برش چینه­شناسی در ناحیه فارس درونی (برش فیروزآباد) با ستبرای 270 متر و ناحیه فارس ساحلی (برش بستک) با ستبرای 286 متر برگزیده شد. در هر دو برش سازند آسماری به طور عمده از سنگ­آهک و سنگ­آهک مارنی ساخته شده است. بر پایه فرامینیفرهای بنتیک 4 بیوزون با سن الیگوسن (روپلین- چاتین) تا میوسن (آکیتانین) شناسایی شدند. واکاوی رخساره­ها منجر به شناسایی 12 رخساره وابسته به گروه­های رخساره­ای رمپ درونی (پهنه کشندی و لاگون)، رمپ میانی (شول) و رمپ بیرونی (دریای باز) شد که در یک رمپ کربناته هم­شیب با شیب ملایم مربوط به محدوده زمانی روپلین تا آکیتانین نهـشته شده­اند. ارزیابی فراوانی رخساره­ها نشان می­دهد که گروه رخساره­ای رمپ بیرونی بیش­ترین فراوانی را در برش فیروزآباد دارد و گروه رخساره­ای رمپ درونی بیش­ترین گسترش را در برش بستک دارا می­باشد. یافته­ها نشان می­دهد که در زمان نهشته شدن سازند آسماری ژرفای حوضه از فارس درونی (برش فیروزآباد) به سمت فارس ساحلی (برش بستک) ژرف­تر شده است.

چکیده [English]

The  Asmari Formation Oligo-Miocene is one of the main petroleum reservoir in the Middle East. To determine the biostratigraphy characteristics, facies types and sedimentary environments two stratigraphic sections in the internal Fars (Firouzabad section) with 270 meters thick and in the costal Fars (Bastak section) with 286 meters are collected. In both sections, Asmari Formation is largely composed of limestone and marly limestone. Based on distribution of benthic foraminifera four biozones with ages Oligocene (Rupelian to Chattian) to Miocene (Aquitanian) are distinguished. Facies analysis let to identification 12 microfacies belonging to inner (tidal flat and lagoon), middle (shoal) and outer ramp (open marine) facies groups that have been deposited in a homoclinal ramp with gentle slope during Rupelian to Aquitanian age. Frequency evaluation of facies indicates that outer ramp facies group shows most frequency in Firuzabad section and inner ramp facies group (specially lagoon subenvironment) is most aboundant facies group of Bastak section. Results shows that during Asmari Formation deposition, the Basin depth of internal Fars (Firuzabad section) has been deeper than costal Fars (Bastak section).
