摘要
大庆外围盆地依—舒地堑方正断陷是石油地质条件最好的地区,先后分别提交了石油和天然气三级储量.方正断陷勘探结果表明：断裂构造是最主要的构造类型,断裂对油气的运聚成藏及后期调整改造均具有重要控制作用;新安村组和宝泉岭组一段是主要的含油气层段,发育扇三角洲沉积体系、水下扇沉积体系、湖泊沉积体系、水下重力流沉积体系;通过对典型油气藏解剖,方正断陷主要有6种类型油气藏,评价优选柞树岗次凹、东部大罗密构造带和德善屯次凹为下步有利勘探区带。
Fangzheng Fault Depression of Yi-Shu Graben in Daqing peripheral basins possesses the best petroleum geological conditions,and has referred three grades of petroleum and natural gas reserves.The results of the depression exploration show that the faults are the most major structure type,the faults have played an important role in controlling the hydrocarbon migration,accumulation,later adjustment and stimulation ; Xin ＇ an Village Formation and Member-1 of Baoquanling Formation are the principal petroleum-bearing intervals,and moreover the fan delta sedimentary system,underwater fan sedimentary system,lake sedimentary system,underwater gravity flow sedimentary system are well-developed ; Through the anatomy of the typical oil and gas reservoirs,6 types of oil and gas reservoirs are found in Fangzheng Fault Depression,and furthermore based on the evaluation and selection,Zuoshugang Subsag,Daluomi tectonic belts in the east and Deshan Village Subsag are considered to be the next favorable exploration areas and belts.
