| 摘 要： | 大型、构造复杂的三维物理模型可用于模拟油气勘探。构造逼近实际地质状况的模拟具有制作技术难度大、质量控制严格等特点,可用于采集宽方位、多方位和全方位的地震数据,从而进行多种三维处理、解释方法验证。本文针对中国西部前陆盆地地表条件复杂地下构造复杂,导致成像不理想等问题,基于复杂的地下构造,设计制作了目前世界上模拟施工面积最大、构造最复杂的KS(塔里木盆地克深勘探工区)物理模型。本文的模型技术的进步主要涉及3个方面:模型的设计方法、模型的浇铸流程和数据采集,首次给出了物理模型的三维真实速度模型,定量分析了物理模型的制作精度,绝对误差小于3mm,可以满足方法试验的需要。该模型基于三维形态测量技术建立了三维真实速度模型,可作为方法试验的基础数据。因此,该模型可作为地震物理模拟技术的标准。 |

| Abstract: | Large-scale 3D physical models of complex structures can be used to simulate hydrocarbon exploration areas. The high-fidelity simulation of actual structures poses challenges to model building and quality control. Such models can be used to collect wideazimuth, multi-azimuth, and full-azimuth seismic data that can be used to verify various 3D processing and interpretation methods. Faced with nonideal imaging problems owing to the extensive complex surface conditions and subsurface structures in the oil-rich foreland basins of western China, we designed and built the KS physical model based on the complex subsurface structure. This is the largest and most complex 3D physical model built to date. The physical modeling technology advancements mainly involve 1) the model design method, 2) the model casting flow, and 3) data acquisition. A 3D velocity model of the physical model was obtained for the first time, and the model building precision was quantitatively analyzed. The absolute error was less than 3 mm, which satisfies the experimental requirements. The 3D velocity model obtained from 3D measurements of the model layers is the basis for testing various imaging methods. Furthermore, the model is considered a standard in seismic physical modeling technology. |
