Abstract：Software-integrated platform for petroleum exploration and development(abbreviated as PSP) serves as a desirable consistent interface layer between exploration-development applied softwares and operation environment(data,users,hard-ware/system software/communication).The article describes not only POSC stanlord systen which is a basis of PSP but also the application and characteristic of PSP 1.0 version.PSP consists of 10 major parts which belong to the data platform,system platform and user platform.PSP coincides with POSC,and its softwares have good characteristics such as reliability,easy development,transplantation,exchange-ability and so on.The successful design of the software-integrated platform indicates that Chinese petroleum software engineering wins a new development.
