  1. According to the abundance well logging, mud logging and core analysis data, gaotaizi reservoir has been classified into four sand group with the principle of cycle comparison and classified control. based on the detailed study of lithologic character, sedimentary structure, paleontologic fossils, depositional sequence, rock association and logging data, the microfacies of the studied area are divided into such seven types : subaqueous distributary channel microfacies ; river mouth bar microfacies ; subaqueous interdistributary channel microfacies ; subaqueous crevasse channel microfacies ; subaqueous natural barrier microfacies ; distal bar microfacies ; delta front sheet sand microfacies. the characteristic of each sedimentary microfacies are described detailedly

    通過研究大量測井、錄井資料和巖芯資料，依據「旋迴對比，分級控制」的原則，把研究區高臺子油層劃分為g 、 g 、 g 、 g四個砂層組。通過對研究區巖性、沉積構造、古生物、沉積序列、巖石組合及測井曲線特徵進行研究的基礎上，認為研究區高臺子油層屬於三角洲前緣亞相沉積，並將研究區沉積微相劃分為：水下分流河道、河口壩、水下分流河道間、水下決口扇、水下天然堤、遠砂壩、席狀砂等七種微相類型。
  2. Based on the review, the fluid flow and heat transfer in the curved circular and rectangular pipes have been researched by employing perturbation method and numerical simulation with a physical model under the rotational orthogonal curvilinear coordinate in a rotating curvilinear pipe with multi - parameters. we firstly analyzed the fully developed fluid flow and heat transfer, mixed convection heat transfer, the development of flow and heat transfer in the inlet in different cross section ( circular, elliptical, annular and rectangular crossection ). the variations of the secondary flow, axial velocity, distribution of temperature, the friction force on the wall, the ratio of friction factor as well as the nusselt number with different dimensionless parameters had been examined in detailed

    本文在總結和分析了一個世紀以來有關曲線管道流動和換熱特性的研究成果的基礎上，以旋轉正交曲線坐標系統下的多參數旋轉螺旋管道中的對流傳熱為物理模型，通過攝動方法和有限體積法，首次對各種截面（圓截面、橢圓截面、環形截面、矩形截面）旋轉曲線管道內充分發展流動的流動結構和傳熱特性（包括耦合對流傳熱特性）以及旋轉曲線管道開口段發展流動的流動結構和換熱特性進行了系統的數值模擬和理論分析，詳細討論了各種無量綱參數對管道內軸向速度分佈、二次流結構、溫度分佈、壁面摩擦力、摩擦系數比以及管道nusselt數的影響，獲得了若干創新性成果。
  3. First super - low specific - speed centrifugal pump has a long and narrow flow passage for its high head and low capacity, and the power absorbed by disc friction is too high, so the efficiency is very low ; secondly the diffusion of flow passage is so high, that the reserved flow often emerges at the inlet and outlet of impeller. therefore the h ~ q characteristic curve is often hump - shaped, and at the low - capacity operating condition the instability often occurs ; thirdly the centrifugal pump at high - capacity operating condition is easy to overload because the n ~ q curve appears a rising trend

    首先由於它的揚程較高、流量較小，所以它的流道狹長，圓盤摩擦損失較大，效率相對較低；其次由於它的流道擴散較嚴重，易在葉片進口產生迴流和在出口產生脫流，揚程流量特性曲線易出現駝峰，在小流量工況下易產生不穩定現象；第三，由於其功率流量曲線呈現上升趨勢，在大流量區運行時電機易過載。
