分形拟合理论在沉积地层密度建模中的应用

将复杂表面的分形插值重建技术应用于地下底层密度建模，以某油田29口钻井在不同深度平面上岩芯密度的实际测量值作为原始数据，从2000～3000m深度上每隔50m作为一个深度层面，建立了这一深度空间内沉积地层的密度模型。该模型为建立重力场模型提供了初始模型和密度空间约束的对比性研究，同时也为特殊岩性体进行基于地址-物理模型的位场参数成像和刻划能力研究提供了可靠的基本模型。

Research on fractal simulative theory in density modeling of deposit layer

The fractal algorithm was first used in density modeling for the oil field. According to density datum from 29 wells in different stratum as original data, from 2 000 to 3 000 m depth in vertical, every other 50 m as a stratum, a depth vacuum density model is established. And it offers an original model for contract research between original model and restriction of density space for gravity field model. It also offers credible basic model for researching gravity field parameter imaging and scoring capability which based on geologic\|physical model of special rock.
