Abstract
In order to understand the effect of secondary perforation on screen pipe strength, the finite element models of bullet hole were established with the help of software ANSYS when the positions of secondary and original perforation were different, and then the effect of secondary perforation on the residual intensity of screen pipe was analyzed. The results show that the best position for secondary perforation is regions near the midline. With the favorable position, large oil and gas flow area can be ensured which will result in higher oil recovery efficiency. And the goals of secondary perforation can be met by enhancing residual intensity of screen pipe. At the same time, the intersection of secondary and original perforation bullet hole should be avoided, if it can’t be avoided, the cross hole central angle should be more than 90 degree, because that the residual strength will grow with the increase of central angle.关键词
