Ansai oilfield is a typical low-permeability, low pressure, and low productivity reservoir. The new oil well only can be built by fracturing, and most of other wells still need multiple fracturing to improve its productivity. Therefore, the fracturing technology has being actively explored and improved since the 1980s in Ansai oilfield; and has been basically formed two technical systems as "water control" and "volume fracturing". This paper reviews the development of fracturing, analyses the existing technology adapted in Ansai oilfield, and points out developing direction of fracturing technology in order to provide the reference for the similar reservoir.
