Further, on the basis of removing the factors which affect seismic velocity, such as earth′s surface, seismic processing technique and particular lithesome, the comprehensive researches indicate that the east prominent is intimately adjacent to the gas generating sag, and the reservoir bed and capping bed arrangement condition is very good. The east prominent has the feature of late gas accumulation and has the petroleum geology conditions of forming large scale natural gas pool.

This reservoir is a mesotype shallow full-contained gas field, which is formed by 5 gas stacked formations in vertical. The buried depth is from 900m to 1200m, average porosity is 11.83%, average effective permeability is 0.28 X 10~-3 u m2. So this reservoir belongs to low permeability gas reservoir.

该气藏是由5个气层纵向叠置而成的浅层中型整装气藏，埋深900-1200m，平均孔隙度11.83%，平均有效渗透率为0.28×10~(-3)平方微米，属于低渗透砂岩气藏。

The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.

由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境，中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程，可以新近纪、古近纪和中生代为界将气田的形成归为 4类：1超晚期生烃成藏型；2晚期生烃成藏型；3早期生烃聚集和晚期定型成藏型；4早期生烃成藏型。在这 4类中，以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

Due to a series of large or oversize scale oolitic gas pools were found in Feixianguan Formation in NE Sichuan Basin, the gas exploration have a good prospect. The questions about origin and accumulation of the natural gas in oolitic reservoir have been one of the focus in the field of petroleum geology.

四川盆地东北部飞仙关组一系列大型、特大型鲕滩气藏的发现，显示出该区巨大的勘探潜力和良好的勘探前景，有关鲕滩天然气的成因、来源及成藏等问题，是当前油气地质学研究的热点之一。

The analysis of group component, stable carbon isotopic compositions and biomarker, and the geochemical characteristics of the oil and gas show that the oil comes from the Palaeogene and the oil reservoir is new bed-generating and old bed-storing; the gas comes from Carboniferous-Permian and the gas reservoir is old bed-generating and new bed-storing.

通过对油气族组成、稳定碳同位素组成及生物标志化合物进行油气地球化学研究，认为东濮凹陷三叠系砂岩裂缝性油藏原油来源于古近系，油藏类型为新生古储式；天然气来源于石炭-二叠系，气藏类型为古生新储式。

Based on the background information on the part of the existing strategy adopted by the Beijing Gas Group, this paper conducts a detailed analysis of strategic issues of this group company by using such analytical tools as SWOT Matrix, Boston Matrix and Portor's Five Forces Model. The author discusses the status in quo of global gas market and domestic market, the internal environment of the group company, and the structure of gas industry. The major strategic problems of the group company are summarized on the basis of above-analysis, including the obsolete thoughts of decision makers, the weak management system of human resources, the deviation on building corporate culture, and the teetering on information processing.
