应对科技发展提出的法律问题是当前法学界的重要议题之一。但目前国内针对法律与科技的社会科学研究仍然较少。这表明,传统法社会学所持有的方法论限制了法社会学的问题意识。开拓对中国的法律与科技的社会科学研究,需要进行方法论反思。通过追溯科学技术研究领域内的方法论变迁,以及英语世界已有的科技、社会和法律研究的研究成果,可以发现法社会学研究进路中的社会建构主义和制度中心主义是影响法社会学提出法律与科技问题的主要因素。因此有必要借鉴国外社会—法律研究的经验,引入科学、技术与社会(STS)和行动者网络理论对法社会学加以改造,从而实现对法律与科技的社会科学研究,为法学领域的制度建构、价值争论提供事实基础。

Research on the solid particle erosion wear of pipe steel for hydraulic fracturing based on experiments and numerical simulations

Petroleum Science 2024年第4期21卷 2779-2792页

作者： Si-Qi Yang Jian-Chun Fan Ming-Tao Liu De-Ning Li Jun-Liang Li Li-Hong Han Jian-Jun Wang Shang-Yu Yang Si-wei dai Lai-Bin Zhang State Key Laboratory of Oil and Gas Equipment CNPC Tubular Goods Research Institute Key Laboratory of Oil and Gas Safety and Emergency Technology China University of Petroleum Oil Production Technology Research Institute of Liaohe Oilfield Company Tianjin Gas Storage Branch PetroChina Dagang Oilfield Company Petroleum Production Engineering Research Institute Daqing Oilfield Company

Erosion wear is a common failure mode in the oil and gas industry. In the hydraulic fracturing, the fracturing pipes are not only in high-pressure working environment, but also suffer from the impact of the high-speed solid particles in the fracturing fluid. Beneath such complex conditions, the vulnerable components of the pipe system are prone to perforation or even burst accidents, which has become one of the most serious risks at the fracturing site. Unfortunately, it is not yet fully understood the erosion mechanism of pipe steel for hydraulic fracturing. Therefore, this article provides a detailed analysis of the erosion behavior of fracturing pipes under complex working conditions based on experiments and numerical simulations. Firstly, we conducted erosion experiments on AISI 4135 steel for fracturing pipes to investigate the erosion characteristics of the material. The effects of impact angle, flow velocity and applied stress on erosion wear were comprehensively considered. Then a particle impact dynamic model of erosion wear was developed based on the experimental parameters, and the evolution process of particle erosion under different impact angles, impact velocities and applied stress was analyzed. By combining the erosion characteristics, the micro-structure of the eroded area, and the micro-mechanics of erosion damage, the erosion mechanism of pipe steel under fracturing conditions was studied in detail for the first time. Under high-pressure operating conditions, it was demonstrated through experiments and numerical simulations that the size of the micro-defects in the eroded area increased as the applied stress increased, resulting in more severe erosion wear of fracturing pipes.

与各种非参数化纠缠度量相比,参数化纠缠度量显示了其优越性.并发纠缠被广泛用于描述量子实验中的纠缠.作为一种纠缠度量,它与特定Rényi-α熵有关.本文提出了一种基于Rényi-α熵的参数化两体纠缠度量,命名为α-对数并发纠缠.与现有的参数化度量不同,首先定义了纯态的度量,然后推广到混合态.进一步验证了α-对数并发纠缠满足纠缠度量3个条件.展示了对纯态的度量是容易计算的,然而对于混合态,解析计算只适用于特殊的双量子位态或特殊的高维混合态.因此,本文致力于建立一般两体态α-对数并发纠缠的一个下界.令人惊讶的是,这个下界是这个混合态的正部分转置判据和重排判据的函数.这表明了3种纠缠度量之间的联系.有趣的是,下界依赖于与具体态相关的熵参数.这样我们可以选择适当的参数α,使得Gα(ρ)≫0用于特定态ρ的实验纠缠检测.此外,计算了isotropic态的α-对数并发纠缠的表达式,并给出了d=2时isotropic态的解析表达式.最后,讨论了α-对数并发纠缠的的单配性.建立了两个量子比特系统中并发纠缠和α-对数并发纠缠之间的函数关系,然后得到了该函数的一些有用性质,并结合Coffman-Kundu-Wootters(CKW)不等式,建立了关于α-对数并发纠缠的单配性不等式.最终证明了单配性不等式对于α-对数并发纠缠是成立的.
