摘　　要：随着泥页岩油气藏勘探程度不断深入,水平井数量成倍增长,给水平井测井评价带来机遇与挑战,但水平井测井解释方法还停留在直井思维上,且水平井响应特征与直井存在较大差别.而泥页岩储层砂泥薄互层发育,各向异性、非均值性非常严重,砂体横向上不连续,给测井解释评价造成很大困难.本文根据实际资料,采用交互式反演方法,以寻找井眼轨迹与目的层的精细关系为目的,探索了泥页岩油气藏水平井测井评价方法以及应注意的事项.The number of horizontal wells growing exponentially with the development of exploration of the shale oil and gas, these bring big opportunities and challenges to the evaluation of horizontal well, but the interpretation methods are still stuck in the thinking of vertical well, also the respond characteristics are different in horizontal wells and vertical wells. Due to the development of sandstone thin interbed, the anisotropy and heterogeneity are serious, sand laterally discontinuous, these resulting greater difficulties in the log interpretation. This paper based on the actual data and around the relationship between the well trajectory and the target layer, explored the evaluation method of horizontal well and some problems we should pay attentiorL
