摘要: 海洋压裂船高压管汇为压裂液提供高压通道,当前国内外压裂高压管汇研究集中在结构优化、冲蚀磨损、振动以及无损检测等方面,无法定量评估爆破失效后产生的爆破能量和冲击特性。对高压管汇爆破能量进行了量化表征,研究出高压管汇的爆破能量和等效TNT当量计算方法;爆破危害以冲击波为主,按人体损伤和物体破坏程度不同,将爆破区划分为极严重损伤区、严重损伤区、中等损伤区、轻微损伤区4个区域;仿真分析得出了能量隔离板在管汇爆裂后的最大形变、最大应力幅值、最大升压速率的分布规律。研究可用于海洋压裂高压管汇爆破能量计算和后果预测,也可为高压安全施工、防护以及评估提供依据及参考。

Abstract: The high-pressure manifold of the offshore fracturing vessel provides a high-pressure passage for the fracturing fluid. Currently, the research focuses on structural optimization, erosion and wear, vibration, non-destructive testing and can$'$t quantitatively evaluate the blasting energy and impact characteristics generated after blasting failure. This paper quantitatively characterizes the blasting energy of high-pressure pipelines, and finds a calculation method for the burst energy and equivalent TNT equivalent of high-pressure manifolds; the main hazards of blasting are shock waves, and the blasting area is divided into four areas: extremely severe damage area according to the degree of human injury and object damage, severe damage area, moderate damage area, and minor damage area according to the degree of human injury and object damage. The simulation analysis revealed the distribution patterns of maximum deformation, maximum stress amplitude, and maximum pressure rise rate in the energy isolation plate following a manifold rupture. This study can be used for energy calculation and consequence prediction of pipeline blasting for offshore fracturing vessels. It can also provide a basis and reference for safe construction, protection, and evaluation of high-pressure construction.

Key words: offshore fracturing vessels, fracturing high-pressure manifold, blasting energy, impact characteristics, energy isolation plate
