油田呆死井地震驱油技术探讨

The Technology of Downhole Seimic Using Abandoned Wells

利用油田呆死井及其原抽油设备带动井下振动重锤,对固定在油田呆死井储层中部的能量辐射器进行敲击,将重力势能转化为振动波的形式向储层传播并诱导储层产生振动,以降低原油密度,提高储层渗透率并降低含水上升速度。实际振动过程中,假设抽油杆和振动重锤的质量为6 000kg,在井下的振动扰动力可达到10kN。

The shaking hammer's gravitational potential energy could transform to the circumstance of vibration wave and lead the reservoir shaking during propagating by using the abandoned wells and former pumping units propel the downhole shaking hammer knocking at the energy emission cell which fixed at the middle part of reservoir.The crude oil's density will decline while the reservoir's permeability raise.The disturbing force will be 10kN if the pumping rod and shaking hammer weight 6 000kg in actual process.
