摘要
根据甲烷碳同位素法和烃类比值法分析判断该区地表烃类异常主要由深部油气活动所产生。各地球化学指标特征均具有北强南弱的特点 ,表明油气运移方向是由北向南 。
The surface hydrocarbon anomalies in the area was caused by oil and gas activities in deep part, according to the analysis and judgement using the carbon isotope and hydrocarbon ratio. All of the geochemical indicators show that the anomalies are strong in north and weak in south. That means the oil and gas has been transported from north to south. Oil and gas is derived from Huanghua depression in north.
