油气化探技术以检测烃类气体为主的直接方法,具有快速、有效、成本低的优势,在天然气勘探中可发挥积极的作用.通过研究典型气藏上方化探特征与异常规律,提出了适合天然气勘探的化探指标和方法,并以四川新场气田为例,对天然气藏化探异常形成机理进行了探讨,证实了油气化探技术在天然气勘探中的应用是有效的.

Oil and gas geochemical exploration technique is a direct deploration technique based on the detection of the subtle matters dominated by hydrocarbon gases. With its unique advantages of being quick, effective and cheap, this technique can play a positive role in natural gas exploration. By means of study of the characteristics of the geochemical indicators and their anomaly distribution regularities over the typical known gas reservoirs, the most suitable geochemical indicators and methods for natural gas exploration were proposed. And by taking Xinchang Gasfield as an example, the authors explored the formation of (geochemical) anomaly provides additional supports for the effectiveness of the oil and gas geochemical exlporation technique in the expolration for natural gas.
