为准确计算濮城油田沙一、二段原始含油饱和度，从水基泥浆取心井法、电阻率法、阿尔奇公式法、物性公式法、粒度中值经验公式法、驱动压力法、毛管压力法等7个方面进行研究，并探讨各方法之间的异同点，进而进取较合理的油藏含油饱和度值。 In order to accurately calculate the original oil saturation of the first and second sections of Pucheng oilfield, the water-based mud cored well method, resistivity method, Archie’s formula method, physical property method, median particle size empirical formula method, driving pressure method, Stress and other aspects of seven aspects of research, and explore the similarities and differences between the various methods, and then enterprising more reasonable oil saturation value.
