Abstract: In order to predict the reservoir quality of Well Jin 310 in Jin 1 well block of Liaohe Depression of Bohai Bay Basin before drilling，the diagenetic stages of the Member 2 of Paleogene Shahejie Formation were predicted by diagenetic modeling，and the reservoir porosity of the Member 2 of Shahejie Formation was predicted after the porosity prediction model was established considering the integrated effects of sedimentary facies and diagenesis on the porosity of reservoirs.As the results show，secondary pore was well developed in the reservoir located in the middle diagenetic stage A of the Member 2 of Shahejie Formation，and the absolute error between predicted porosity and measured porosity is only 1.33％ in the reservoir with the content of filling materials of 16.13％. Therefore，the method of predrilling reservoir quality prediction considering integrated effects of sedimentary facies and diagenesis on reservoir quality could be applied to the exploration deployment of pre-exploration wells.

摘要： 为了在渤海湾盆地辽河坳陷锦310预探井钻探前预测锦1井区古近系沙二段储集层的质量，文中应用成岩作用数值模拟技术预测了该地区沙二段的成岩阶段，综合考虑成岩作用和沉积微相对储集层孔隙度的影响，建立了孔隙度预测模型，在钻前预测了沙二段的孔隙度。结果表明，锦1井区沙二段储集层在大部分地区处于中成岩阶段A期，次生孔隙发育;在填隙物含量高达16.13％的条件下，锦310井钻前预测孔隙度和钻后实测孔隙度的绝对误差只有1.3％。由此可见，综合考虑成岩作用和沉积相的钻前储集层质量预测方法，可应用于预探井的勘探部署。
