大港滩海沿岸带中浅层油气源对比

Oil and gas source correlation of shallowmid layer of coastal belt in shallowwater and offshore area of Dagang oilfield

研究了大港滩海沿岸带中浅层原油及中深层烃源岩的有机地球化学特征 ,并进行了系统的油气源对比 ;明确了沿岸带东侧明化镇组、馆陶组、东营组原油来自沙一段下亚段、沙二段、沙三段烃源岩混源 。

Organic geochemistry feature of shallowmid layer oil and deepmid layer hydrocarbon source rocks in coastal belt of shallow water and offshore area of Dagang oilfield is investigated,then oil and gas source is correlated systematically. It is definite that the oil of Nm, Ng and Ed in the east of the coastal belt comes from source rocks of lower Es 1 , Es 2 and Es 3 , the oil of upper Es 1 in Mapengkou area comes from source rocks of its same formation.
