摘要
裂缝性气藏水平井钻井方位设计主要从地质和工程角度出发,根据储层裂缝产状、分布和井眼稳定规律设计钻井方位,提高裂缝的钻遇率,优选井眼最稳定的方位钻进。通过裂缝预测、成像测井解释和岩心观测,对新疆油田克拉美丽气田滴西地区石炭系气藏裂缝发育特征进行了分析,并对不同钻井方位水平井井眼稳定规律进行了模拟研究,提出了水平井钻井方位,给出了一套适合克拉美丽气田石炭系裂缝性气藏水平井钻井方位优化设计方法。
The azimuth designing of horizontal well drilling in the fractured gas reservoirs should be based on geological and engineering situations,the drilling azimuth was designed according to occurrence of structures,their distribution,and the rules of wellbore stability to raise the success rate of well drilling and choose the most stable position for drilling. By forecasting fractures,interpreting imaging log data and observing core specimen,the characters of fracture growth in carbonate gas reservoirs in Dixi Area in Kelameili Gas field were analyzed,and the rules of horizontal borehole stabilization in different azimuths were studied by simulation. The drilling azimuths are proposed and a sets of methods are provided for designing drilling azimuthes in carbonate fractured gas reservoirs.
