摘　　要：哈得4油田是近年来在塔里木盆地满加尔凹陷北部发现的第一个海相油田。该油田地质情况复杂,油藏主要储层为石炭系东河砂岩和中泥岩段内的薄砂层。本文对哈得4油田电阻率测井曲线进行了深入的分析,研究结果表明随着岩石粒度的变粗,电阻率标准值相应的变大,利用电阻率测井资料可以有效地判别岩性;该区油层电阻率各向异性不明显,而水层电阻率各向异性相对明显,在水平井中,利用水平电阻率能较好地识别油水层。Hade4 oilfield is the first marine oilfield in the north of the Manjia＇er depression of the Tarim basin. The main reservoirs are the Donghe sandstone and the thin sandstone which wrapped by mudstone of Carboniferous with complex geologic conditions. In this article, the author analysis the resistivity well logging curve of Hade4 oilfield. From the results, we know that the standardized resistivity become lager with the rock grain size become thicker, so we can identify the lith by resistivity well logging data; in this area, resistivity anisotropy is opposite remarkable in water bed but not in oil bed. In the horizontal wells, oil bed and water bed can be discriminated by horizontal resistivity effectively.
