LOGGING RECOGNITION TECHNOLOGY FOR SHALLOW GAS IN LIAOHE OILFIELD
辽河油田浅层气测井识别技术

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 scope for finding the potentiality of the developed oilfield.The cognition of the shallow gas is confined by irregularity of log information and particularity of shallow gas because conventional log parameters are not sensitive enough to the shallow gas.Based on available data,three applicable and suitable methods are adopted to recognize shallow gas in several areas through effectively amplifying the hydrocarbon bearing information,which sufficiently develops shallow gas potentiality and raise the reserve and yield of natural gas that facilitates the natural gas prospecting and development in Liaohe oilfield.The remarkable effects demonstrate that the methods' practicability is good.
