高压石油射孔枪结构优化设计

Structural optimization design of high pressure oil perforating gun

射孔枪多通过加大壁厚增加射孔枪的耐压性能,这种方法不仅增加了枪的自身重量也增加了射孔弹穿孔的能量损失,鉴于此,有一种新的思路,即研究盲孔对射孔枪耐压性能的影响,利用ANSYS软件对射孔枪盲孔相位和孔密进行建模分析,得出盲孔相位和孔密对射孔枪耐压性能影响趋势,根据影响趋势优先选择盲孔相位和孔密。同时新设计分级模块射孔结构—ESUB分级模块化射孔结构,该结构是以模块雷管集成单元内置于中间接头为特征,射孔枪与连接接头采用触点结构实现快速高效连枪的一种分级射孔结构,极大的降低了现场操作的工作量,缩短了枪串长度,提高分级射孔的效率,通过射孔枪管盲孔相位和孔密对射孔枪耐压性能的仿真试验和内部结构设计,优化射孔枪结构和降低了成本。

perforating gun by increasing the wall thickness.This method not only increases the weight of the gun,but also increases the energy loss of the perforating bullet.In view of this,there is a new idea,namely research The impact of blind holes on the pressure performance of perforating guns,using ANSYS software to model and analyze the blind hole phase and hole density of the perforating gun,and obtain the trend of the blind hole phase and hole density on the pressure performance of the perforating gun,according to the influence Blind hole phase and hole density are preferred for trend.At the same time,a newly designed hierarchical modular perforating structure-ESUB hierarchical modular perforating structure is characterized by the built-in modular detonator integrated unit in the middle joint,and the perforating gun and the connecting joint adopt a contact structure to realize fast and efficient gun connection.The graded perforating structure greatly reduces the workload of on-site operation,shortens the length of the gun string,and improves the efficiency of graded perforation.The pressure resistance performance of the perforating gun is simulated by the blind hole phase and hole density of the perforating gun barrel.And the internal structure design optimizes the perforating gun structure and reduces the cost.
