Problems with the fine description of reservoirs

The advantages and disadvantages of fine description of reservoirs in China and abroad were discussed and compared. Some problems in the fine description of reservoirs in China were pointed out, such as the multi-explanation of fracture systems, low accuracy of single sand body prediction, and poor prediction of residual oil distribution and reservoir development rules. Six countermeasures were proposed, including basic geologic experiments, reservoir geology origin analysis, new technique application, comprehensive analysis to reduce multi-explanation, reservoir fine description with dynamic thought, and information platform construction.
