摘　　要：海—塔盆地构造复杂,储层物性差,非均质性严重,导致储层岩性、电性特征复杂,给测井解释带来一系列难题。由于区域岩性多变、矿物成份复杂,特别是该区高阻泥岩的存在,使得自然伽马曲线在反映渗透层和非渗透层上不能很好的发挥作用,因此,岩电关系矛盾大,储层岩性识别、储层划分及地质应用难。本文针对目前海塔—盆地高阻泥岩的识别难情况,采用岩心刻度测井技术,应用薄片（X衍射全岩）分析数据确定矿物成分,了解了高阻泥岩的形成,初步搞清并解决了高阻泥岩的岩电矛盾问题,掌握了高阻泥岩的主要测井响应特征,在实际生产中提高了储层划分的精度。Haita basin has a poor reservoir property and great heterogeneity due to complicated structure and including pyroclast in terrigenous clasts. It results in complex lithology and electric property and causes difficulty to log interpretation.In particular,gamma ray curve can't reflect permeable formation and impervious formation preferably because of identifying high-resistance mudstone difficulty and the contradiction of lithological-electrical Relation.It leads to reservoir zonation miss and geological applications mistake.Iri this paper,aiming at identifying high-resistance mudstone difficulty in haita basin,we know the formation of high-resistance and solved the question of lithological-electrical contradiction and grasp the variation of various log responses by means of core calibration logging and chip X-ray diffraction analysis for various lithology data.It reduces by the mistakes of taking mudstone for reservoir stratum.
