【摘要】 针对玛北油田BW2井区地震分辨率低、储集层薄且横向变化快、控藏因素复杂等实际情况,结合该区构造背景、沉积特征和储集层的发育特点,利用对储集层敏感的电阻率曲线进行地质统计反演,根据已知井对比情况,精细刻画了8套含油砂体,基本查明目前出油砂体的纵向和横向展布规律,通过对各个含油砂体平面位置的叠加,划分出含油有利区,对开发井网的部署具有一定的指导意义。该方法弥补了地震资料分辨率低的缺陷,有效地提高了储集层的纵向分辨能力。更多还原

【Abstract】 BW2 well area in Mabei oil field is characterized by low seismic resolution,thin reservoir and rapid variation laterally,and complex reservoir-control factors.Combined with the structural setting,the sedimentary feature and the reservoir rocks characteristics,this paper figured out 8 oil-bearing sand bodies by the geostatistic inversion using resistivity curves with sensitivity to the reservoir and makes comparisons by using given wells,and determined the vertical and lateral distribution of the oil-bearing sand bodies.The favorable oil-bearing areas were found out through plane position stacking of each sand body.This method can make up the shortage of low resolution of seismic data,effectively improve the vertical resolution of reservoirs.更多还原
