Taking Block J as an example, this paper comprehensively uses drilling coring, logging, dynamic monitoring and other data, and uses dynamic monitoring analysis technology, logging secondary interpretation technology, coring analysis technology, micro-structure identification technology, etc. to clarify the distribution law of remaining oil on the plane, between layers and within layers, and formulates reasonable technical countermeasures for different remaining oil distribution patterns, including sidetracking potential tapping, improving injection-production well pattern, optimizing injection-production well sections, strengthening water injection in potential layers, optimizing perforation well sections, etc. Good results have been achieved, with an increase in oil production of 120 tons and a gradual increase in oil production of 60,000 tons. Indicators such as the water cut increase rate and natural decline rate of the block have been improved. It is estimated that the ultimate recovery rate of water flooding is 35.5%, which is 5.5 percentage points higher than the nominal recovery rate. The recoverable reserves have been increased by 1.425 million tons, and the development life of the block has been prolonged. The results and understanding obtained can provide reference for other oil reservoirs.展开更多
