摘　　要：塔里木地区库车山前构造复杂,目的层上部盐膏层、高压盐水层发育,使用油基泥浆能解决该地区的安全钻井与地层复杂之间的矛盾。油基泥浆的规模化应用,给测井技术带来巨大挑战,原有水基泥浆电成像测井仪器已不再适用,新的油基泥浆电成像测井应用效果难以与原有水基电成像测井效果媲美。为了对比不同泥浆类型对电成像测井的影响,塔里木油田在同一口井进行了水基泥浆/油基泥浆替换实验,详细对比了不同工况下电成像测井仪器的测量效果。以塔里木油田目前应用的几种油基泥浆电成像测井仪器为研究对象,对比了几种仪器结构及原理并对其应用效果进行分析。研究认为,结合仪器特性和储层特征,根据具体需求选择性应用,在油基泥浆井况下同样可以达到地质特征识别和储层综合评价的目的。The structure of Kuqa foreland basin in Tarim oilfield is complex and the reservoir is covered by the gypsum bed and high pressure salt water, the oil-based mud can solve the contradiction between the safety drilling and the complicated formation. Large scale application of oil-based mud may bring challenge for well logging, so the micro resistivity imaging tools are no longer applicable in the water-based mud, but the effect of imaging tools in oil-based mud cannot be comparable to the effect in the water-based. In order to compare the different effects of the micro resistivity imaging tools in the oil-based mud and in water-based mud, an experimental study is carried out to obtain the micro resistivity image in different mud of the same well. Based on the large data of four kinds of oil-based resistivity imaging tools applied in Tarim oilfield, the structure and principle of these tools with their application effect are analyzed. The micro resistivity imaging tools in the oil-based mud can evaluate the reservoir with other logging data comprehensively.
