| Abstract: | Be aware of the production decline law of tight reservoir is helpful to realize the effective production and benefit development of this kind of reserves. Based on the analysis of the historical production data of the production wells in Honghe 92 well block, the types of production decline in different production stages are defined. The production index and hyperbolic decline model of Chang 8 tight reservoir are established, and the future production and decline rate of production wells are calculated and predicted by using the model. At the same time, some development strategies such as moderate water injection, volume fracturing and "pressure production" integration are proposed to provide reference for effective production of undeveloped reserves in tight reservoirs. |
