北美页岩气开发已获得了巨大成功，而中国页岩气开发还处于起步阶段，对比分析中美页岩气储层条件，指导中国页岩气高效开发意义重大。从页岩气的成藏条件、储层特征和储层评价因素3个方面进行了详细对比分析，结果认为：中国成藏条件更复杂，储层埋藏深、温度高、热成熟度高、厚度低；中国页岩矿物组成更复杂，黏土矿物以伊/蒙混层和伊利石居多，以微粒运移性的黏土矿物为主；石英含量更高，脆性指数更大，更有利于压裂改造；中国储层评价因素更复杂，要从有机碳含量、有机质成熟度、干酪根类型、储层有效厚度和岩石学特征等多个方面进行评价。总之，从储层条件的角度对比情况来看，中国（尤其是四川盆地）页岩气藏已具备规模化开发条件。
北美頁巖氣開髮已穫得瞭巨大成功，而中國頁巖氣開髮還處于起步階段，對比分析中美頁巖氣儲層條件，指導中國頁巖氣高效開髮意義重大。從頁巖氣的成藏條件、儲層特徵和儲層評價因素3箇方麵進行瞭詳細對比分析，結果認為：中國成藏條件更複雜，儲層埋藏深、溫度高、熱成熟度高、厚度低；中國頁巖礦物組成更複雜，黏土礦物以伊/矇混層和伊利石居多，以微粒運移性的黏土礦物為主；石英含量更高，脆性指數更大，更有利于壓裂改造；中國儲層評價因素更複雜，要從有機碳含量、有機質成熟度、榦酪根類型、儲層有效厚度和巖石學特徵等多箇方麵進行評價。總之，從儲層條件的角度對比情況來看，中國（尤其是四川盆地）頁巖氣藏已具備規模化開髮條件。

The exploitation of shale gas has been greatly successful in North America,while it is just starting out in China. Comparing the conditions of shale gas formation in China with those in America,it is of great significance to better exploit shale gas. This paper compared and analyzed 3 aspects in detail:the conditions for accumulation of shale gas,the properties of reservoir and reservoir evaluation factors. Through comparison,we get the following conclusions. The conditions for accumulation of shale gas in China are more complex,because the reservoir has properties great depth,high temperature, high thermal maturity and thin thickness. The mineral composition of shale gas in China is more complicated. The main clay minerals are andreattite and illite,both of which are fine grain migrating minerals. On the other hand,the shale contains more quartz,which leads to a higher brittleness index. Therefore,the fracture operation can be well applied,reservoir evaluation factors are also more complex in China. In order to evaluate the shale gas formation,it is necessary to take organic charcoal content,organic maturation,kerogen type,net pay thickness and lithological feature into consideration. In all,from the aspect of reservoir conditions,the shale gas reservoir in China,especially in Sichuan Basin,has already been equipped with the large scale exploitation conditions.
