具有独立传爆部件的射孔弹及其射孔工艺研究

Perforating Charge and Perforating Technology With Independent Transmission Detonation Component

油田开采中射孔效果分为两种:一种是小孔径深穿透,另一种是大孔径但穿透很浅。本文提出一种新型具有独立传爆部件的射孔弹及其射孔工艺,较好的解决了大孔径、深穿透这个问题,通过其独特的二次子弹复合射孔工艺,达到了射孔和压裂两大目的,通过在辽河油田某采油厂四口井的实验,取得了很好的效果,为油田增产增收创造了条件。

There are two perforating effects in oil field production at present：one is deep penetrating small aperture,another is shallow penetrating big aperture.A kind of perforating charge and perforating technology with independent transmission detonation component was proposed,which solves deep penetrating big aperture problem by its unique double composite perforating technology on perforator.It realizes the purpose on perforating and fracturing,and creates the conditions on incresing production,attains the good effects in an oil production plant in Liaohe oil field by experiments.
