摘要
通过塔河油田多口水平井成像测井资料与常规测井资料的对应关系,结合测试资料,初步建立了根据水平井常规及成像测井资料划分储层等级的划分标准,并将奥陶系碳酸盐岩储层划分为3类。钻井方位与水平井裂缝走向的交角影响水平井的产能。钻井方位与水平段裂缝走向的交角越大,则钻遇裂缝越多,越有利于酸压沟通储集体,油气产能越好;反之,钻遇裂缝越少,油气产能越差,该结论可以指导后期水平井钻进方位。
Based on comprehensive analysis of the correspondence between imaging logging data and conventional logging data among many horizontal wells in Tahe oilfield,combined with test data,the division standard of reservoir is established initially by conventional and imaging logging data in carbonate formation in horizontal well.The angle between the direction of crack and the orientation of drilling has an important impact on the production in horizontal wells.The angle of the direction of cracks and the orientation of drilling is bigger,the possibility to drill cracks is greater,so the reservoirs are easier to communicate and the production is higher.On the contrary,the smaller the angle is,the few the cracks are drilled and the lower the production is.This conclusion can guide the drilling position of the horizontal well later.
