摘　　要：针对断层附近布井风险大的问题,根据断块油藏构造和油层发育特征,利用断层倾角、地层倾角及油层底面与目的层顶面距离的空间几何关系,建立了反向正断层对开发布井影响的数学模型,并绘制了3种参数的关系图版,揭示了其对油田开发布井的影响。结果表明:开发井与断层上盘的最小距离(简称最小距离)和油层底面与目的层顶面距离呈正相关性;断层倾角与地层倾角和最小距离呈负相关性,且相比地层倾角,断层倾角对最小距离的影响更加明显。应用数学模型,在A区块进行了井位部署,并取得了良好效果。研究结果为反向正断层附近开发井位部署提供了理论依据。There is high risk in well placement near fault. According to the fault-block oil reservoir structure and reservoir properties,the fault dip,stratum dip and the spatial geometry between reservoir bottom and interest- reservoir top are used to establish a mathematical model to evaluate the effect of antithetic normal fault on well placement. A plate to characterize 3-parameter relationship is drawn to reveal their effects on oilfield well placement. Research shows that there is a positive correlation between the minimum distance between development-well and upper-wall( the minimum distance) and the distance between reservoir-bottom and interest-reservoir top. This minimum distance presents a negative correlation with fault dip and stratum dip and the minimum distance is more sensitive to fault dip that that of stratum dip. This mathematical model is successfully used in the well placement of Block A. Research could provide certain theoretical references for the oilfield development-well placement near antithetic normal fault.
