当通过钻井、完井射开油层时，由于井中的压力低于油层内部的压力，在井筒与油层之间就形成了一个指向井筒方向的压力降。在原始条件下，油层岩石与孔隙空间内的流体处于压力平衡状态，一旦钻开油层，这种平衡就被破坏。这时，由于压力降低引起岩石和流体的弹性膨胀，其相应体积的原油就被驱向井中。如果地层压力足够的话，就可将原油举升到井口以上，形成自喷采油；如果地层压力不能将原油举升到井口，那么就需要借助某些人工举升的办法采油，或者向油层中注入某种流体提高地层压力，使油井生产能量有所改善。

Answer 1

When through drilling, completion shoot open the reservoir, due to the well pressure below the pressure within the reservoir, wellbore and reservoir in the form of a link between the direction of wellbore pressure drop. In the original conditions, reservoir rocks and fluids inside the pore space in the pressure equilibrium, once the oil drilling, this balance was destroyed. At this time, due to pressure caused by reduced elasticity of the rock and fluid expansion, and its corresponding volume of oil was driven to the wells. If the formation pressure is sufficient, that would give rise to the wellhead of crude oil over the formation of oil from the spray; if the formation pressure can not give rise to the wellhead of crude oil, then you need to use some method of artificial lift oil, or injected into the reservoir improve the formation of a fluid pressure, so that oil production capacity has improved.
