Reservoir pressure decline, the increase of recovery rate and the damage of rock structure are main reasons of micro fine migration and sand production during oil recovery process of such reservoirs.

疏松砂岩油藏开采过程中，油层压力下降和采油速度的增加以及岩石结构的破坏，是造成油层岩石微细粒运移和油井出砂的主要原因。

In low and ultra-low homogeneous reservoir start-up pressure have an impact on the flow rate, reservoir production decline law, water production laws and injected water sphere of influence.

低和特低均质储层中的渗流启动压力对渗流速度、油藏产量递减规律、产水规律和注入水的波及范围都有影响。

They decline significantly from one year to the next because each barrel of oil taken from a reservoir reduces the pressure within the field, leaving less force available to push the next barrel of oil up the well.
