摘　　要：数据处理方法研究是三探测器岩性密度测井研究的一个重要方面。在Monte Carlo模拟的基础上,提出了2种三探测器岩性密度测井求取地层光电吸收指数Pe和进行泥饼校正求取地层密度ρb的方法;就三探测器岩性密度测井仪DTLD-2的围岩补偿功能进行了研究。结果显示了用计算机模拟方法研究核测井问题可以节省建造实体物理模型的费用和人力,具有广泛的应用前景。Data-processing method is one important part in three-detector density logging . In light of log data from two sets of three-detector density logging tools, the article puts forward method for gaining photoelectric absorption coefficient Pe and formation density pb with Monte Carlo simulation after mudcake correction. At the same time, the article studies the shoulder bed compensating function of three-detector density logging tool DTLD-2. Logging results indicate that computer simulating can save expenses and manpower in building entity physical model and has wide applications in studying nuclear logging.
