Abstract: Energy is the main factor restricted the economic development of our country，but our convention oil and gas
resource has already gone into the stage of decreasing production. Therefore，developing shale gas is an important way to
solve the problem. Fracture operating is related to the productivity，recovery and economic effectiveness，so it′s the key to the
development of shale gas. This paper introduces the stimulation mechanism and operating techniques of shale gas，and gives
some suggestions of shale gas development of our country. First，we analyze the geology of gas shale and suggest strengthening
the evaluation of brittleness and natural fracture；and then，we expound the stimulation theory of stimulated reservoir volume
and analyze the influencing factors of shale gas production. In the end，we analyze all kinds of operating techniques which
could be used in shale gas development，giving some new perspectives and suggestions of research direction.

Key words: shale gas, stimulation mechanism, reservoir evaluation, stimulated reservoir volume, net fracture
