Abstract: Wangchang oil field is located in the fault subsidence basin of Salt Lake in Jianghan area. Effected by both the fault and rock salt. it has a special geology and recovery pattern. The unfavorable aspects of the field include the deep w ef Is. thin pay zones, low permeabilities, and the serious corrosion of wellbore facilities caused by salt and gypsum scalling. The favorable aspects include the steep formation structure, reverse rhythmic deposit and water wet rock. So high waterflooding sweep efficiency and high saline—oil displacement efficiency are obtained. In this paper the geological characters and waterflooding development results are summerized. The practical experience of steady and high procuction is reviewed. An example of the use of dynamics in field geology and development is given. The goal of extending the duration of steady and high production is proposed.
