随着吉林油田勘探与开发工作的深入,油气勘探逐步由中央凹陷向外围扩展。勘探区块的地下地质构造越来越复杂,勘探难度不断加大。针对复杂构造成像问题,结合科研项目,进行叠前去噪方法研究。本文总结吉林探区的去噪方法研究应用情况,并通过实例展示应用效果。 With the exploration and development of Jilin Oilfield, oil and gas exploration gradually expanded from the central depression to the periphery. The underground geological structure of the exploration block is more and more complicated, and the exploration difficulty is constantly increasing. Aiming at the problem of complex structure imaging, combined with research projects, the prestack noise reduction method is studied. This article summarizes the research application of denoising method in Jilin Exploration Area and shows the application effect through examples.
