辽河油田虽具有浅层气形成的有利条件,但由于历史原因,浅层气未得到应有的重视,这为目前的老区挖潜提供了广阔的空间。可是,常规测井参数对浅层气响应不强,加之浅层测井资料的参差不齐和浅层气的特殊性又限制了对浅层气的认识。结合现有资料,因地制宜地采用了3种方法,有效地放大了浅层的含油气信息,对多个地区的浅层气进行了识别。

The conditions for shallow gas are perfect in Liaohe oilfield. For the historic  reason, less importance has been put to shallow gas, which leaves extensive scop e for finding the potentiality of the developed oilfield. The cognition of the s hallow gas is confined by irregularity of log information and particularity of s hallow gas because conventional log parameters are not sensitive enough to the s hallow gas. Based on available data, three applicable and suitable methods are a dopted to recognize shallow gas in several areas through effectively amplifying  the hydrocarbon bearing information, which sufficiently develops shallow gas pot entiality and raise the reserve and yield of natural gas that facilitates the na tural gas prospecting and development in Liaohe oilfield. The remarkable effects  demonstrate that the methods' practicability is good.
