New Study Reveals Key Reservoirs in Oil-bearing Formation, Impacting Sand Distribution
The main sedimentary system of the Chang 2_1 oil-bearing formation in Jiyuan district is front-delta deposition. There are six types of sedimentary microfacies, including distributary channel deposits and river mouth bar, which are good reservoirs in the area. Understanding the sedimentary facies is crucial for studying sand distribution in the region.
