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 the correlation between the multi-well horizontal well imaging logging data and conventional well logging data in Tahe Oilfield and the test data, the division standard of reservoir classification based on horizontal well conventional and imaging well logging data is preliminarily established, and the Ordovician carbon Acid rock reservoirs are divided into three categories. The intersecting angle between drilling azimuth and horizontal well fractures affects horizontal well productivity. The larger the intersection angle between the drilling azimuth and the fractures in the horizontal section, the more drilled the fractures, the better the acid pressure communication reservoir, and the better the oil and gas production. On the contrary, the less drilling cracks and the worse oil and gas productivity, this conclusion can guide Late horizontal well drilling azimuth.
