摘要:

动态负压射孔可完全清理射孔孔道内压实带，但对清理的射孔孔道内压实带岩屑的介质难以有正确认识。对安装与未安装封隔器的动态负

压射孔进行现场测试，分别得到动态压力曲线，研究二者动态负压变化特征。结果表明，安装封隔器的动态负压射孔中，动态压力负压值持续时间长，金属射流侵彻油

气储层形成的孔眼中，其介质是金属射流侵入岩石产生的高压气体；射孔孔道内携带碎屑及压实带岩屑进入到井筒中的涌流发生在井筒压力下降阶段。该研究可优化动

态压力最小值，避免因动态压力差大导致井筒损坏。

Abstract:

Dynamic underbalance perforating can completely clean the compaction zone in the perforating tunnel, but it is difficult to correctly

understand the medium for cleaning the compacted devris in perforation tunel. The dynamic negative pressure with and without the packer were

tested in the field and the dynamic pressure curves were obtained respectively to study the dynamic underbalance presssure changges. The results

show that the dynamic pressure values lasts for longer time in the dynamic underbalance perfotaing with a packer. The medium  can be inferred

to be as the high pressure gas genetrated by the metal jet penettrating the rock  of the oil and gas reservoir. the surge flow that carries debris

and compacted deberis into the wellbore occurs during the wellbore pressure drop phase. This study can be used to optimize the dynamic

pressure minimum to  aviod the wellbore damge under the high pressure difference.
