Abstract :
Jahrom Formation is one of the important reservoir formations of Zagros basin, which was studied in one of the 330 meters thick Golkhari oil field wells in order to identify microfacies and sedimentary environment. In this research, based on the study of microscopic thin sections, 8 microfacies were identified, which are spread in 4 facies belts, including tidal flat, lagoon, shoal, and open marine environments. These microfacies are located along the tidal flat (shallow), lagoon, shoal and open sea (deep) areas and include the following: 1- mudstone, 2- bioclastic benthic foraminifera (imperforate) wackestone - packstone, 3- benthic foraminifera (perforate and imperforate) packstone, 4- redalgal floatstone, 5- Nummulites assilina wackestone-packstone, 6- Discocycline wackestone-packstone, 7- foraminifera (benthic-plankton) wackestone-packstone, 8- plankton foraminifera mudstone-wackestone. Therefore, all microfacies are located in the environment of the carbonate platform and in the inner, middle and outer ramps.
