渤海湾盆地辽河坳陷锦310预探井钻前储集层质量预测

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。

Predrilling reservoir quality prediction of Well Jin 310 in Liaohe Depression of Bohai Bay Basin

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 wa...
