大油气田 meaning in Chinese
major field
Examples
- Because of the high ratio of sandstone in the shallow water and high ratio of mudstone in the deep water area , the hydrocarbon scattered into the sandstone more easily in the shallow water area , so large oil & gas fields appear to form more easily in the deep water area
由于浅水区砂岩百分比含量高，砂体连通性好，油气聚集比较分散，比较而言深水区油气在扇体里富集程度较高，更有利于形成大油气田。 - This paper also probes into reservoir properties of the sand - bodies and suggests that point bar and mid - channel bar sand - bodies can be considered the high quality reservoirs for great oil - gas field , and the formation of oil - gas pool not only be related to reservoir quality of sandbodies , but also to regional tectonic conditions
本文还探讨了各类砂体的储集物性特徵，认为点砂?和心滩砂体是形成大油气田的优质储层，而油气藏的形成除与砂体的储集物性有关外，主要与区域构造条件密切相关。
