Abstract:Based on static analysis and combined with the petroleum reserves classification and the dynamic information, such as testing well, production test well and development well data, the variation of pressure and output data in each type of reservoir block was analyzed, the production rate maintenance capability of each type of reservoir block is evaluated quantitatively using well testing technology, and the reservoir dynamic analysis study was carried out in Chaochang area. The research in this article lays a significant foundation for forecasting deliverability accurately, submitting high quality proved reserves and making development plan for later stage.
