摘要:
在实验室条件下，用同种内置式复合射孔器单元在4种不同的靶上进行射孔并测试环形空间〖WTBX〗p—t曲线，然后检测靶体。通过实验结果的对比分析表明：相同的内置式复合射孔器单元在不同的靶上射孔时的p—t曲线不同，靶越致密则气体的峰值压力越高，持续时间越长，在孔隙度18.4〖WTBZ〗%、渗透率0.102 μm2的砂岩靶上形成了3条长裂缝。靶的性质决定〖WTBX〗p—t曲线特点，可以利用p—t曲线判断复合射孔效果。
Abstract:
The same type of combined perforator unit perforated in 4 different kinds of targets in laboratory. p—t curves in annulus space and targets were tested. Comparative analysis of the test results show that different targets perforated by the same unit present different p—t curves, in which denser targets have higher peak pressures and longer duration. Three long fractures are generated in the sandstone targets with a porosity of 18.4% and a permeability of 0.102 μm2. Characters of p—t curves, which are responded by the properties of targets, can be used to determine the combined perforation effects. 
