| 摘 要： | 通过对尚家—太平川地区构造演化、烃源岩特征、沉积特征、储盖组合、油水关系及油藏类型和油气成藏特征的分析,研究了本区的石油地质条件,认为烃源岩具有较好的生、排烃能力,分流河道砂体为油气聚集提供较好的沉积环境,良好的储盖组合有利于油气的聚集与保存。研究区没有统一油水界面,尚家地区以岩性—构造油藏为主,太平川地区以构造—岩性油藏为主。区内扶余—杨大城子油层油气成藏受有效性圈闭、优势运移通道、过剩压力、储集条件和构造诱导作用控制。据上述认识确定了研究区下一步的勘探方向,并已在指导勘探实践中取得了较好的效果。

| Abstract: | Shangjia-Taipingchuan area,as a new exploration district,is situated in the Central Depression of Songliao Basin.By deepened study on the regional structural evolution,characters of source rocks,sedimentary features,reservoir and cap rock combination,the oil and water relationship,as well as the types of oil-bearing pool and oil accumulation in the area,the petroleum geological conditions were analyzed.The results revealed that the source rocks there had a relatively good ability for hydrocarbon production and discharge.The sandbodies of distributary channel supported a good sedimentary environment for hydrocarbon accumulation,furthermore,the favorable reservoir and cap rock combination was suitable for incidence of accumulation and preservation.There was no unified oil-water boundary in the studied area.The exploration in Shangjia area should mainly focus the attention on lithological-structural hydrocarbon-bearing pools,while in Taipingchuan area should on structural-lithological pools.In the studied area,the petroleum accumulation in the Fuyu-Yangdachengzi Oil Layer was controlled by effective trap,good migration channel,overpressure,accumulation conditions and structural inducement.Based on what mentioned above,the next exploration targets were analysed,which had make a good result in guiding exploration practice. |
