Net paythickness is one of the factors affecting the Precision of volumetric method.
用容积法计算石油储量时影响储量计算精度的因素之一是储层有效厚度。

So we suggest that combined perforating technique should be applied to the area where there is lower clay content, less porosity and moderate paythickness.
故在泥质含量低、孔隙度小、油层厚度适中的地区，建议应用复合射孔技术。

The broad application of directional drilling has brought some difficulty to the net paythickness determination for single well during the reserve calculation with volumetric method.
