动态负压射孔是一种在射孔瞬间清理射孔孔道的新方法,其原理是通过快速吸收井筒内的残余爆轰能,使井筒内压力在射孔后瞬间下降,产生瞬间冲击回流,冲洗射孔孔道及孔道周围压实带,从而解除压实,提高油气井产量。

除具备复合射孔主要功能外,对动态负压射孔,可以分别计算开口及闭口情况下动态负压p-t曲线;动态负压射孔与常规射孔对油气产能影响计算;动态负压射孔不同井底压力下的地面流量随时间变化计算等。

Dynamic negative pressure perforation is a new method to clean the perforation channel at the moment of perforation. The principle is to reduce the pressure in the wellbore immediately after perforation by rapidly absorbing the residual detonation energy in the wellbore, resulting in instantaneous impact reflux, flushing the perforation channel and the compaction zone around the hole, so as to remove compaction and increase the production of oil and gas wells.

In addition to the main functions of compound perforation, for dynamic negative pressure perforation, the dynamic negative pressure p - t curve under open and closed conditions can be calculated, the influence of dynamic negative pressure perforation and conventional perforation on oil and gas productivity, the calculation of surface flow rate under different bottom hole pressure of dynamic negative pressure perforation over time and so on function.
