Abstract: 在成岩作用数值模拟的基础上,通过建立辽河拗陷双清地区不同沉积微相成岩指数,ID与储层平均有效孔隙度的相关模型,预测了该地区古近系Es3下储层的孔隙度,恢复了孔隙演化史,确定了有效油、气储层的分布范围.孔隙度预测的结果表明,有效油、气储层分布于孔隙度大于8.5%和5.8%的斜坡区.储层预测平均孔隙度与实测孔隙度之间的绝对误差为2.8%,而研究区储层的填隙物含量在1.2%~45.0%之间,平均为16.9%.由此可见,这种模型可用于填隙物含量较高储层的钻前孔隙度预测和孔隙演化史模拟.孔隙演化史的模拟结果表明,储层孔隙度在埋藏早期主要受沉积相的影响,而在晚期则主要受成岩作用的控制.
