摘  要:
鄂尔多斯盆地是我国重要的产气基地,研究区位于鄂尔多斯盆地东南缘,区内钻井显示存在致密砂岩地层,且有致密气产出。对研究区二叠系下石盒子组和山西组致密砂岩储层厚度进行预测,由于该储层较薄,地震上不易识别。在现有地震解释成果的基础上,利用叠后地质统计学反演技术精细刻画该储层在横向和纵向上的变化,反演结果与钻井结果符合率较高,说明地质统计学反演技术对薄砂岩有较好的识别功能。

摘  要:
Ordos Basin was an important gas-producing base in China.The study area was located in the southeastern margin of Ordos Basin.Well drilling indicated that there existed tight sandstone formations and tight gas production in the area.The tight sandstone reservoir thickness of lower Shihezi Formation and Shanxi Formation of Permian System in the study area is forecasted,because the reservoir is thin,it is not easy for seismic identification,based on the existing seismic interpretation results,the poststack geostatistical inversion technology is used for fine description of the reservoir in the horizontal and vertical directions,and the inversion results is highly in agreement with that of drilling,it indicates that the geostatistical inversion technique has better recognition function of thin sandstone.
