| 摘 要： | 低孔隙度低渗透率砂岩油层常需进行水力加砂压裂改造.为了防止压开围岩,将压裂缝控制在产层段内,需要预测给定施工压力下储层压裂缝的延伸高度.分析压裂缝延伸机理、确定压裂缝形态和方位及延伸方向；利用测井资料计算地层应力和破裂压力,定性分析压裂缝延伸情况.压裂缝的形态取决于地层应力的大小和方向,裂缝的方位垂直于最小水平主应力方...

| Abstract: | Hydraulic fracturing is necessary for low porosity and low permeability sand-shale reservoir.This needs us to predict the fracture extending height in some given pressures to avert fracturing the surrounding rocks and control the fractures in the reservoir.Firstly,this thesis analyses how to know the height of fractures,how to sure the shape and azimuth of fractures and extend directions.Log data are used to forecast the formation stress and fracturing pressures and qualitatively analyse the fractures exten... |
