摘要
马泉油页岩测井物性特征表现为中高三侧向电阻率、高自然伽玛、高声波时差、中低密度的"三高一低"测井响应特征.通过常规测井曲线定性定量解释油页岩,划分地层,进行对比;通过水文测井曲线解释含水层,计算出含水层补给速度及补给量;利用声波时差、密度、井径等测井参数计算力学性质,评价岩体软弱性;并对该区油页岩放射性异常特征进行分析.测井技术及相应资料在该区的应用已取得了一定的地质效果.
The oil shale in Maquan area has the and one low" such as the middle and high three logging response characteristics of "three high lateral resistivity, high natural gamma, high a- coustic time difference, low and medium density. The oil shale is qualitatively and quantitative- ly interpreted and the stratum is divided and compared by using of the conventional well logging curve. The aquifer is interpreted and the supply speed and recharge of aquifer are calculated by using of the logging curve. The mechanical properties of rock are calculated and the weakness of rock is evaluated by using of the logging parameters such as the time difference, density and well diameter, and the radioactive anomaly of the oil shale in Maquan area is analyzed. The well logging technology and its application have achieved good geological results in Maquan area.
