摘　　要：准噶尔盆地金龙2井区火山岩油藏水平井投产整体效果较好,但也存在部分井轨迹偏离产层从而导致产量较低的情况。该区储层分布复杂,水平井目标优选及轨迹优化设计难度大。基于地震、录测井资料,针对该油藏进行三维地质精细建模,结合前期钻井资料结果落实储层空间展布,实现模型的精细刻画与修正。通过建立的精细三维地质模型,优化水平井轨迹设计,提高了油层钻遇率,并大幅度增加了油井产量。Horizontal wells of volcanic reservoirs in Jinlong 2 well area of Junggar Basin have a good overall effect.However,some wells deviate from the production zone,which leads to low production.The reservoir distribution in this area is complex,and it is difficult to optimize the target and trajectory of horizontal wells.Based on seismic and logging data,three-dimensional geological fine modeling is carried out for the reservoir,and spatial distribution of the reservoir is implemented by combining the results of previous drilling data to achieve fine characterization and correction of the model.Through the establishment of a fine three-dimensional geological model,the trajectory design of horizontal wells is optimized,the drilling rate of reservoirs is increased,and the production of oil wells is greatly increased.
