Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] An explosion vessel 1 for flash photography of the long radiation flow of petroleum perforating charges, which is composed of a middle cylindrical section and ellipsoidal heads located at both ends of the middle cylindrical section. A flash photography front window 2, 3, 4 with a diameter of 320mm is used to illuminate the lower, middle and upper sections of the long radiation flow respectively; 45° distribution is set, and the elevation difference of the flash photography front window of adjacent heights is the same, that is, the elevation difference of the flash photography front window 2 and the flash photography front window 3 is the same as the elevation difference of the flash photography front window 3 and the flash photography front window 4.

[0024] In order to simultaneously perform three-dimensional flash photography on the oil perfor...

Abstract

The invention discloses an explosion container for flash photography of the long radiation flow of petroleum perforating charges, which is composed of a middle cylindrical section and ellipsoidal heads located at both ends of the middle cylindrical section. There are three front windows for flash photography, and the three front windows for flash photography are arranged at 45° distribution along the angle between the center of the cross-section of the middle cylindrical section, and the front windows for flash photography at adjacent heights have the same elevation difference. In the same horizontal direction as the two sides of the flash photography front window in the middle of the height direction, two small windows are respectively arranged on the middle cylindrical section, and the included angle between the two small windows and the flash photography front window in the middle along the center of the cross section of the middle cylindrical section Both are 45°. The three flash machines of the present invention can take pictures of the long radiation flow of about 2 meters through three different elevation front camera windows; The structure is simple and the use is convenient.

Description

technical field [0001] The invention relates to an explosion container, in particular to an explosion container for flash photography of the long radiation flow of petroleum perforating bullets, which can be used for flash photography experimental research on the long radiation flow produced by petroleum perforating bullets. Background technique [0002] It is an effective method in the research and design of perforating charges to study the long radiation flow of petroleum perforating charges by using flash photography experiment. To protect flash cameras and negatives from air shock waves and high-speed fragmentation groups, experiments of this type are generally carried out in explosion towers. However, the construction cost of the explosion tower is high, the maintenance and use are inconvenient, and due to the cumulative and irreparable nature of concrete damage, there are potential safety hazards after a certain number of years of use. The explosion container made of ...
