It is considered that Baojiaochang Carboniferous reservoir is featured by low porosity, low permeability and high gas saturation based on the comprehensive evaluation.
综合评价，芭蕉场石炭系储层为为低孔、低渗、高含气饱和度储层。
Recovery efficiency of oil reservoir is not high for thin oil-water two-phrase region and low movable oil saturation.
油水两相区区域较窄，油藏可动油饱和度较低，油藏采收率不高；
Initial oil saturation is controlled by the reservoir boundary and structural. Parts of the reservoir with high initial water saturation dose not form effective edge and bottom water drive.
含油饱和度受油藏边界和构造形态控制，油藏南部边缘和局部构造低部位原始含水饱和度高，但不形成有效边底水驱动。
