A油田是大庆西部外围地区的典型低渗透油田,主要目的层萨尔图油层具有储层薄、物性差、含泥含钙重的特点,其水淹层常规测井响应特征不明显,识别难度较大。为解决这一难题,研究从水淹层导电机理入手,分类建立了水淹层解释图版和标准,同时考虑测井的局限性,利用录井和动态水淹分析成果对测井水淹层解释结果进行补充和修正,建立了测井-录井-动态水淹层综合解释方法。应用该方法,水淹层解释符合率达75.0%。
A oil field is a typical low-permeability oilfield in the periphery of western Daqing. The main target reservoir is characterized by thin reservoirs, poor physical properties and mud with heavy calcium content. The conventional well logging response characteristics of water flooded layer are not obvious, Larger. In order to solve this problem, the paper studied the conductive mechanism of water flooded layer, established the illustrated charts and standards of water flooded layer, and considered the limitations of logging at the same time. Using logging and dynamic flooding analysis results to explain the well logging flooded layer The results were supplemented and amended, the establishment of a well logging - Logging - dynamic water flooded layer comprehensive interpretation method. Applying this method, the water flooding layer explains the coincidence rate of 75.0%.
