摘要:
選取SQ89×8.8 mm射孔槍,利用ANSYS軟件建立射孔槍的有限元模型,通過仿真分析不同壁厚、不同盲孔深度的等深盲孔和不等深盲孔對射孔槍耐壓性能的影響。等深外盲孔比不等深盲孔射孔槍的耐壓性能平均提高15.5%; 采用較深盲孔深度的等深射孔槍,其耐壓性能可超過較淺盲孔深度的不等深盲孔射孔槍的耐壓性能; 在滿足相同耐壓要求情況下,可以采用深度較大的等深外盲孔結構以減少盲孔處槍管壁厚,進而減少射流穿透盲孔的能量損失。分析溫度、軸向拉力載荷、槍長、接頭對射孔槍耐壓性能的影響,為耐高溫耐高壓射孔槍的研制提供新的思路。
Abstract:
The finite element model of the SQ89×8.8 mm perforating gun is established by using the ANSYS software to simulate and analyze the pressure-resistant performance of the perforating gun with isobathic blind holes and varied-depth blind holes under the conditions of different wall thicknesses and different blind hole depths. The results show that: the perforating gun with isobathic blind holes exhibits a pressure-resistant performance 15.5% higher on average than the perforating gun with varied-depth blind holes; the perforating gun with deeper isobathic blind holes has a higher pressure-resistant performance than the perforating gun with shallower varied-depth blind holes; and given the consistent pressure-resistant requirement, the deeper isobathic external blind holes are preferred to reduce the wall thickness of the perforation gun at the positions of blind holes, thereby reducing the energy loss when jet penetrates the blind holes. Moreover, the effects of temperature, axial tension load, gun length and joint on the pressure-resistant performance of the perforating gun are analyzed, providing a new reference for the development of HTHP-resistant perforating gun.
