摘要：

东濮凹陷深层的沙三段储层为致密砂岩,储层物性较差,但储层中裂缝发育,极大地改善了储集性能。盐间层高压流体引起的天然水力破裂作用,以及东营期末期抬升卸载与应力释放引起的天然破裂作用,是该区微裂缝的重要成因。

Abstract:

The reservoir rock of the third member of the Shahejie Formation in Hubuzai, DongpuDepression is compacted sandstone with poor petrophysical property, but its reservoiringproperty improved a great deal due to well-developed fractures within the reservoir rock. It isconsidered that the hydraulic fracturing that was resulted from high-pressure fluid of saltinterlayers and the regmagenesis caused by uplift--unloading and stress release are importantorigin of the fractures in the area.
