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 hydrocarbonratio.
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。

This practical ripe technique can provide with accurate geologic basis for improving oil and gas exploration success ratio and calculation of hydrocarbon reserves.
可为提高油气勘探成功率及油气储量计算提供准确的地质依据，是一项实用的成熟技术。
