Determining the minimum economic resource for gas exploration ( i . e . the minimum proven gas in place obtained by the exploration investment ) is the requirement to improve the decision - making level of gas exploration investment and the problem for the decision maker of exploration investment to solve urgently 摘要确定天然气储量最低经济规模（即相对于勘探投资要求探明天然气资源的最低数量）是提高天然气勘探投资决策水平的需要，也是勘探投资决策者迫切要求解决的问题。
This essay concerns on current situation of natural gas exploration and development and marketing development in chuanzhong oil & gas mines . as per reserved source of natural gas has not well prepared and the new tendency of natural gas market , developing strategy should be based on natural gas exploration and marketing development , meanwhile , implement through natural gas exploit strategy to realize resource guarantee and market expansion 本文考察了川中油气矿天然气资源勘探开发现状及市场发展现状，针对天然气后备资源准备不充分及天然气市场的新形势，提出了天然气发展战略要以天然气资源勘探为基础，以市场发展为导向的思路，通过天然气发展战略的实施，来实现资源的保证和市场的扩充。
This paper , in accordance with the basis theoretical problems for natural gas exploration in deep - formation in the north of songliao basin , according to the practical features , point out that gas source condition ( gas - generating amount , gas - generating intensity , gsa - generating period ) and reservation condition ( cap rocks , faults , dissipation of natural gas ) are main controlling factors determining accumulation of natural gas , and emphatically studied generation , dissipation and conservation of natural gas in geologic history to acquire objectively and rationally the resource amount of deep - formation natural gas on the basis of investigating the development of natural gas exploration theory and technology from home and abroad 本文在调研了国内外天然气勘探理论与技术发展的基础上，针对松辽盆地深层天然气勘探所面临的基本理论问题，从天然气的特点出发，指出气源条件(生气量、生气强度、生气期)和保存条件(盖层、断层、天然气扩散)是决定天然气富集规模的主控因素，并重点对松辽盆地深层天然气在地质历史中的生成、扩散和保存进行了深入研究，为客观合理地获取深层天然气资源量奠定基础。
According to the new criterion for classification of oil and gas resources / reserves ( gb / t19492 - 2004 ) issued in 2004 , this paper reviews the studied methods at home and abroad for the purpose of establishment of new series of recoverable reserves such as technically recoverable reserves , economic recoverable reserves , sub - economic recoverable reserves and remaining economic recoverable reserves of oil - gas fields 摘要按照2004年颁布的新的《石油天然气资源储量分类》 ( gb - t19492 - 2004 )标准，为了建立和形成油气田技术可采储量、经济可采储量、次经济可采储量和剩余经济可采储量等新的可采储量系列，在总结国内外研究方法的基础上，结合油田的地质开发特点，根据我国现行的财税制度，以现金流法为主要方法，进一步研究提出了经济极限法、井网密度法、边际成本法、类比法等经济可采储量计算方法。
