求翻译：本次对扶杨油层共8个油层组的砂岩和有效砂岩厚度进行了预测。为了确保本区岩性预测结果的精度，我们利用区内测井资料齐全的103口（共111口）探井和评价井进行叠前弹性反演，利用叠前横波阻抗反演成果得到各油层组的砂岩预测平面图，各油层组已知井砂岩预测的绝对误差在0.1－0.9m之间，精度较高，为河道砂体预测奠定了基础，是什么意思？

The Fuyang oil layer thickness of 8 Group sandstone reservoir and effective sandstone were predicted. In order to ensure the accuracy of the results of this lithology prediction, we use a full range of logging data in the region 103 (111) exploration and appraisal wells pre-stack elastic inversion u

The Rotary Club of Yang reservoir a total of 8 a group of sandstone reservoir sandstone and the effective thickness for the projections. In order to ensure that the lithology of the forecast accuracy results in the area, and we use logging information of 103 port (for a total of 111 ports) wells and

This time to held the Yang oil layer altogether 8 oil measures the sandstone and effective sandstone thickness has carried on the forecast.In order to guarantee the home court lithological character forecast result the precision
