【摘要】 水平并技术是世界石油工业的一次革命，它克服了直井和斜井钻遇油层厚度小、成功率低的缺点，可最大限度控制石油地质储量，提高油层最终采收率．应用三维地震资料设计水平井，技术关键是层位标定、油层标定、油层产状的精确计算及时深校正，进而在各套油层的高部位，设计出最少的钻井进尺钻遇最多油层的水平井黄金轨迹．更多还原

【Abstract】 The technique of horizontal well is a revolution of the petroleum in the world. It overcomes the shortcomings of the vertical well and the deviated well which drilled fewer oillayer thickness and have lower success rate.The horizontal well not only can control oil reserve maximally,but also increase the final oil recovery rate. The keys to design horizontal well by using seismic data are the horizon calibration,the oil-layer calibration,the strike of oil layer calculation and the time-depth conversion.So the golden trajectory of the horizontal well,which drills the maximum oil-layer in minimal drilling footage,have been designed at the highest point of the oil-layer.更多还原
