海洋压裂船高压管汇爆破能量及冲击特性分析
Blast Energy and Shock Characteristics of High-pressure Manifold in Offshore Fracturing Vessels
摘要
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.关键词
