某油田进入中后期开采,集输系统能耗呈现大幅上升趋势.通过对集输系统现状的深入分析,采用常温不加热密闭集输工艺、原油低温预脱水、功图计量等技术,优化简化了整个系统,使
CANMET材料技术实验室在2009年完成了《阴极保护对高强钢开裂的作用(The Effect of Cathodic Protection on Cracking of High-Strength Pipeline Steels)》最终研究报告.与
本文针对油田集输效率测试过程中对影响测试准确度和测试工作效率的因素,如测试标准的适用性、现场工艺动态参数的采集、现场计量器具的配备等进行了分析,通过对影响因素的分
In this paper we discuss the convergence rate for Galerkin approximation of the stochastic Allen–Cahn equations driven by space-time white noise on T2. First w
为避免管道大范围出现屈服,提出管道试压时的压力-容积图非线性偏转量一般情况下不能超过0.2％、特殊情况下不能超过0.4％的非线性偏转量;为避免管道局部出现较大塑性,提出试压后
By using the coupling method and the localization technique, we establish non-uniform gradient estimates for Markov semigroups of diffusions or stochastic diffe
普光气田高含硫化氢,一旦泄漏失控将导致灾难性后果,在线安全监测是保证普光气田安全开发的重要手段.传感器将数据传输到OPC服务器中,根据OPC技术规范,通过C＃语言编制客户端程
Stochastic analysis occupies a central place in modern probability theory. Besides its intrinsic value as an area of mathematical research, its importance also
In this work, by constructing optimal Markovian couplings we investigate exponential convergence rate in the Wasserstein distance for the transmission control p
对于敷设于复杂山地的高含硫化氢湿气集输管道,积液通常会积聚于管道低洼处.积液的存在会降低管道输送能力,引起压力的急剧波动,加剧系统腐蚀.本文建立了气液两相流双流体模
