摘　　要：自酸化射孔弹是利用固体酸作为射孔弹药型罩的一部分,伴随射流进入射孔孔道内,当井筒液体进入孔道后,和固体酸溶合成为酸液,在射孔孔道内产生类似基质酸化的作用,溶解孔隙间的颗粒及堵塞物,扩大孔隙空间,解除近井地带的储层污染,从而达到增产增注的目的。Self acidification Perforated charge uses solid acids as part of a perforated liner ammunition,along the jet into the perforation tunnel,when the well bore fluid into the channel,acid fluid is formed synthesized with solid acid and that produces a function of acidification like the matrix in the perforation tunnel to dissolve particles and clog in the pores,expand pore space,Released near well-bore reservoir contamination,so as to increase production by injection purposes.
