摘　　要：针对哥伦比亚Girasol油田的油藏特征及含油层系平面上、纵向上的分布状况,选择在主力层系采用水平井开发并在试验区实施。在水平井钻井过程中采用先进的地质导向技术,能够根据随钻测试电阻率和伽马值的变化,选择最优储层段钻进,并采用Mesh Rite专利防砂筛管完井。同时,该试验井组还在国际上首次采用EZ-GAUGESYSTEM(井底温度和压力实时监测系统),为油藏动态监控提供了必要的基础参数。水平井开发在试验区的成功实施,将进一步促进水平井技术在Girasol油田的推广应用。Considering Girasol Oilfield’s reservoir characteristics and oil-bearing lateral and vertical distribution,horizontal wells were selected to develop the main layer and implemented in pilot area.Advanced geosteering technology was used for drilling horizontal wells.This technolgy selects the optimal formation to drill according to resistivity and Gamma Ray change.And the well was completed using the patented Mesh Rite sand screen completion technique.Meanwhile,the EZ-GAUGE SYSTEM bottom hole temperature and pressure real-time monitoring system was used for the first time in the world,all these provide the necessary basic parameters for reservoir dynamic monitoring.The sucessful application in pilot area promotes using horizontal wells to develop the entire field.
