So far , the exploration and exploitation of the oil-gas
have mainly concentrated on the above H3 in Miyang
depression ,as it has been seriously explored and exported ,to
find rich oil-gas traps becoming more and more difficult , In
order to increase the oil reserves and stabilize the yields ,the
exploration vision should be expanded and the exploration
field should be enlarged ,in which can the exploration of the
oil2gas be newly broken-through. The author of this article
concludes after some researches. The next step of the
exploration of Miyang depression should focus on the oil2gas
of the deeper layer and the shallower layer. The deeper layer
system includes the below H3 and Dacangfang group. The
shallower layer system includes the H2 , H1 and the
unconformity top of Liaozhuang group.
