After the reserves of unassociated gas being increased fast, it is asked to adjust the main direction of natural gas development to deepen exploration of natural gas in the two basins in the central part and the regions (eg.the areas of northern and southern Tianshan mountains) near pipelines in China.It is suggested that tight gas reservoirs should be enhanced to explore,e...

在气层气储量快速增长后，应当调整我国天然气勘探主攻方向：深化中部两盆地和管线附近的天然气勘探；加强致密气藏勘探，特别是滚动勘探开发工作；对海上天然气应加大投入，除南海北部和东海外，还要注意渤中坳陷轻质油分布区的气层气勘探，还要按隆起和坳陷的不同情况开拓黄海这个战略后备区；东部中小气田经济价值高，作为地下气库应发挥更大作用。

Firstly, with the analysis of electric characteristics of a condensate gas reservoir, we find that there are some differences between Tri\|porosity logging amplitude, Deep Investigation Laterolog, Shallow Investigation Laterolog, and Microlaterolog, etc; secondly, in view of the feature of the condensate gas reservoir, the log interpretation model is built on the basis of the correlation of four reservoir parameters, and the reservoir grade scale is completed using conventional logging techniques combined with cross plot technique and the result of well testing; finally, according to the feature of Qiketai Formation and Sanjianfang Formation in the Hongtai oil field, we set up the reservoir classification criteria and divide the reservoir parameters into four types.

以吐哈盆地红台地区为例，对凝析气层的电性特征进行了分析，认为凝析气层在三孔隙度测井曲线幅度和深、浅、微电阻率等方面存在差异。针对研究区凝析气藏特点，在关键井&四性&关系研究的基础上，建立了储层参数测井解释模型，采用交汇图技术和实际试油、试气资料相结合的方法，对研究区目的层常规测井储集层的分类标准进行了分析，并结合红台气田七克台组和三间房组凝析气藏特点，建立了研究区储层参数分类评价标准，依据该标准将红台地区储集层划分为4类。

As small gas and hydrogen index causes the calculated effective porosity of a gas zone smaller than that of formation,.

由于储层含气含氢指数小，导致气层核磁共振测井计算的有效孔隙度小于地层孔隙度，含气显示越好的储层核磁测井解释的有效孔隙度越小。

Differences are analyzed between those responses to non hydrocarbon (CO_2) gas zone and hydrocarbon gas zone.
