The research results showed that under the condition of invariable in-situ stress magnitude and distribution,fracture pressure would increase if the perforation angle increased,fracture pressure would decrease if the number of perforation increased.
研究结果表明,在地应力的大小和分布确定的情况下,破裂压力随着射孔角度的增大而升高,随着射孔排数的增加而降低。

计算结果表明,射孔方位角是影响地层破裂压力的主要因素,孔眼长度和射孔孔眼直径的影响不大。
