Abstract: The phase characteristics of reservoir-fluid and development characteristics of gas condensate reservoir with oil rim is especially complex. In the development process,it'simportant to correctly use oil and gas two-phase driving force,properly control oil and gas interface movement,prevent oil into the gas cap and gas channeling,select the development of cost-effective way to enhance the crude oil,con-densate oil and natural gas recovery. According to the geologic characteristic of Chenghai Block 2,combining with the research of reservoir-fluid phase,utilizing reservoir engi-neering theory to design development plan,this paper optimize and evaluate development plans by means of numerical simulation on different development ways and oil and gas recovery rate.
