By comparing vertical fracturing well simulation with a streamline model and black oil model, it was pointed out that in simulation of vertical fracturing wells of hydraulic fracturing by using grid amplification there existed many drawbacks, such as grid orientation, calculating times doubled with the increase of grid number, the heterogeneity of model increased as fracture existence, which resulted in difficulties of equation solution and convergence
摘要通過流線模型和黑油模型模擬垂直裂縫壓裂井的對比分析,指出了在黑油模型中運用網格放大技術模擬水力壓裂垂直裂縫井生產動態存在的諸多缺陷,如網格取向嚴重、計算時間隨網格數目增加而成倍增加、裂縫的存在增加模型的非均質性從而嚴重加大方程的求解難度,方程求解出現不收斂等。The optimal length of crystal was achieved for the characteristics of quasi - three - level. three types of crystal were compared, we select lbo as the main frequency doubler. meanwhile, the other strong spectrum were restrained by suitable coating
從激光晶體的準三能級特性出發,充分考慮增益與損耗之間的矛盾,選擇出最佳晶體長度;對三種倍頻晶體進行了比較,選擇出lbo作為主要倍頻晶體;對膜系進行了必要的分析,在維持946nm譜線振蕩的同時,充分考慮了其它激光譜線的抑制。This paper describes a transistorized low consumption and fast recovery photomultiplier bases. the base developed for detector dissipates less power and recovers faster than its resistor - only ( or rc ) counterpart
摘要介紹了由電晶體化的光電倍增管偏置電路的研究,該電路具有功耗低、穩定可靠、輸出脈沖上升時間快、能量分辨高、脈沖線性好、恢復時間快等優點。The results show that in the later stage of the nucleation process, the maximum slip velocity is monotonically accelerating ; the slipping hot spot ( where the slip rate is maximum ) migrates spontaneously from a certain instant, and such migration is spatially continuous ; when the maximum velocity reaches a detectable order of magnitude ( at least one order of magnitude greater than the loading rate ), the remaining time is 20 hours or more, and the temporal variation of slip velocity beyond this point may be used as a precursory indicator ; the average slip velocity is related to the remaining time by a log - log linear relation, which means that a similar relation between rate of microseismicity and remaining time may also exist ; when normal stress variation is taken into account, time scale of such processes can be extended by about 2 times
結果表明,在成核的後期階段:最大位移速率單調加速增加;滑動熱點(最大滑動速率處)在後期階段開始自發性遷移,且在空間上連續;當最大滑動速率達到可以明顯探測的量級時(高於載入速率一個數量級以上) ,倒計時間為20小時或更長一些,這時的速率變化可作為臨震預測標志;平均滑動速率與倒計時間的關系在臨震階段呈對數線性趨勢,由此可推測微震活動增長率與倒計時間同樣存在對數線性關系;正應力的變化對上述時間尺度有延長作用,使之大致增加到原數值的2倍。分享友人
