摘要
The main body of Chang-6 reservoir in Huaqing region is delta deposition, with the lithology being mainly the fine sandstone. Four-property relation of target section in the region was studied by thin section. Via optimizing the reservoir parameters of quantitative interpretation model, the calculation accuracy of the reservoir parameters increases, which avoided the loss of effective thickness. Finally, in combination with logging method, mercury penetration data, and pressure coring, the research also confirms that the oil-saturation of Chang-6 reservoir is calculated as 71%.
