不同测试方法对射孔弹穿孔性能的评价

Evaluation of Perforation Performances of the Shaped Charge by Different Methods

采用地面模拟装枪穿钢靶试验、整枪穿环形混凝土靶试验和地面模拟装枪穿砂岩靶试验3种不同的测试方法评价一种114型射孔弹穿孔性能。结果表明:在射孔弹方案研制阶段,选择地面模拟装枪穿钢靶试验,试验成本较低,对优化穿深性能有指导意义;地面模拟装枪穿砂岩靶试验作为射孔弹研制后期的评价方法,贴合射孔弹对地层的射孔效能,对油气增产和射孔弹应用更具指导意义。

In this paper,perforating perfor^mance of a Type 114 shaped charge was evaluated by three different test methods which are ground simulating gun penetrating steel target test,full gun penetrating annular concrete target test and ground simulated gun penetrating sandstone target test.The results show that in the perforation program developing stage,test cost of choosing ground simulation penetrating steel target is low,and the optimal penetration depth has guiding significance considering the perforation of realistic use of the environment.Ground simulated gun loading sandstone target test is the evaluation method of the developed stage of perforating bullet,matching the perforating efficiency of the formation,which is of more guidance to the oil and gas production and the shaped charge application.
