摘　　要：江汉油田潜43油组普遍具有油层薄、隔层薄的特点,属于低渗透油藏的第二、三类差储藏,压裂控制缝高难度较大。统计现场压裂施工效果,结合储层岩性特征并应用交会图图版法分析压裂因素,发现影响缝高控制的因素很多,除地应力、储层的杨氏模量、断裂韧性等地质参数外,施工排量、压裂液黏度、前置液量、支撑剂量等因素也可影响裂缝高度的增长。不能仅考虑地质因素或工程参数某一个影响因素,应综合多种因素分析研究。Qian--43 formation of Jianghan Oilfield belongs to second or third--class poor reservoir in low permeability reservoir and features thin oil layers and interlayers, which make it more difficult to control fissure height by fracturing, On the basis of fracturing result, lithologic character of reservoir and analysis of fracturing factors by means of cross- plot, it is found out that many factors influence fissure height control, including operation displacement, fracturing fluid viscosity, ahead fluid volume and proppant volume besides geological parameters such as crustal stress, Young＇s modulus of reservoir and breaking tenacity. It is necessary to integrate a variety of factors in carrying out the research.
