  1. For this purpos, from the point of the log geology, aimed at the actuality of the current fractured reservoir log geology interpretation and evaluation, based on synthetical analysis of the current domestic and foreign fruit of fractal dimension investigation of reservoir fracture, using the method and technique of fractal dimension, through the further discussion of the fractal dimension characteristics of m index and n index in the log interpretation archie model in a sample way and through the theoretic reasoning to the fractal dimension dfa and m index of fractured reservoir interval ' s log curve, according to the geophysical signification of the fractal dimension dfa of fractured reservoir interval ' s log curve shape : the more complicated the change of the curve shape is, the larger the its dfa value is, then the more complicated space structure of fracture and pore, then the higher value of m index of space structure of fracture and pore, and so on, the text propounds an improved method, based on box dimension, of covering log curve with scale grid, and by programming computes the dfa and its m index value of fractured reservoir interval ' s log curve, for instance, ac and rt curve, ect, then further puts this technique into application investigation, and makes analysis of application effects in the reservoirs located in l area of qx oil field from three aspects : 1. the dfa and its m index value of fractured reservoir interval ' s log curve, for instance, ac and rt curve, ect, which are derived from computing, is used to identify reservoir type by crossplotting m index with the product df _ acrt of fractal dimension of acoustical wave log curve and restivity log curve and by experiential discriminance plate of reservoir type in l area of qx oil field

    因此,對該區裂性儲集層的類型識別、孔滲特徵的測井地質解釋以及儲層裂的發育和分佈規律進行深入的研究便成為本文研究的出發。為此,本文從測井地質的角度,針對當前裂性儲層測井地質解釋與評價的現狀,在綜分析當前國內外儲層裂的分形分維研究成果的基礎上,利用分形分維方法和技術,通過對archie測井解釋模型中的m指數、 n指數的分形分維特性的深入淺出的論述以及裂性儲層段測井線分維d _ ( fa )與m指數的理論推導,根據裂性儲層測井線形態分維值的地球物理意義? ?線變化越復雜,則其分維值d _ ( fa )越大、裂孔隙空間結構越復雜、裂孔隙空間結構指數m值越高等特徵,提出了改進的基於盒維數的測井線網格覆蓋法,編程計算了裂性儲層段常規測井線(如聲波和電阻率線)上分形分維值及其m指數值,進而從以下三個方對qx油田l區塊的裂油藏進行應用研究,效果十分理想: 1將計算得到的可變的m指數與聲波和電阻率分維之積df _ acrt進行交繪,採用儲層分維值分類技術統計分析這些參數變化的規律,並結qx油田l區塊儲層類型經驗判別圖版,從而實現qx油田l區塊下白堊統的裂性儲層的類型識別。
  2. Profile curves of a rounding surface are calculated along a feature line with a given radius. then inner elements of a rounding mesh is created with these profile curves, and sewn with the original mesh which is pre - trimmed. a feature - based mesh modification method is proposed for existing rounding feature

    給定圓角半徑,計算出沿特徵線圓角的截輪廓線,以輪廓線的六等分為節生成圓角區域單元,並與剪裁后的基網格,從而生成沿特徵線的圓角網格。
  3. Two different reinforcing methodologies are applied : modification of the overlay characteristics by adding chopped glass fibers to the hot mixture asphalt ( hma ) and reinforcing asphalt overlay with glass grids. theory of fracture mechanics ( fm ) is employed to determine crack growth rates for the suggested anti - cracking overlay systems. asphalt mixture designing tests, three point bending tests and fatigue crack propagation tests were carried out. the critical stress intensity factors kic are determined for plain and reinforced asphalt concrete. depending on the fatigue crack propagation, the crack growth rate is determined for each type of anti - cracking system and the cracking process is also analyzed. one of the significant points in this study is the attempt to give better understanding of the crack propagation for multilayer asphaltic overlay or what are suggested herein to be called composite structure anti - cracking overlay system. the results indicate that the reinforcing materials improve anti - cracking characteristics of the asphalt concrete. composite structure anti - cracking overlay gives a good solution for the reflective cracking phenomenon over old cracked pavements
