密度测井技术是利用岩层对伽马射线的吸收来获取岩层密度,通过中子源放射性测井,完成对井身不同岩层密度的准确测量,录取井深不同岩层密度资料。通过密度测井可以识别岩层的性质,特别是可以利用密度测井数值计算出储层的上覆压力,了解储层的压实效应,进行裂缝形态研究。 Density logging technology uses the rock layer to absorb the gamma ray to obtain the rock mass density. Through the neutron source radioactive logging, the accurate measurement of the rock mass density is completed, and the density data of different rock depths are recorded. Density logging can identify the nature of the rock formation. In particular, the overburden pressure can be calculated using density logging data to understand the compaction effect of the reservoir and study the fracture morphology.
