摘要:
为了更有效地研究偏磨套管的安全性,基于偏磨套管的双圆弧模型和弹塑性理论,结合试验数据,提出了评估偏磨套管破裂概率的压力窗口法,讨论了磨损率对偏磨套管破裂强度的影响。结果显示,偏磨套管的破裂具有一定的规律性,其破裂压力集中于压力窗口中;偏磨套管存在高破裂概率区间和低破裂概率区间;随磨损率的增加,偏磨套管的压力窗口变窄、变小。研究结果可为偏磨套管的安全性评估提供理论依据。
Abstract:
In order to study the safety of casing with eccentric wear more effectively, based on double circular arc model of casings with eccentric wear and elastoplastic theory, combining with the experimental data, a pressure window method to evaluate the failure probability of the casings with eccentric wear was proposed, and the effect of wear ratio on the cracking strength of casing with eccentric wear was discussed. The results show that the cracking of the casings with eccentric wear had certain regularity, the cracking pressure was concentrated in the pressure window; there were a high cracking probability interval and a low one for the casing with eccentric wear ; the pressure window of casings with eccentric wear became narrower and smaller with the increase of wear ratio. The research results could provide theoretical basis for the safety evaluation of casing with eccentric wear.
