Abstract：The Ordovician Yingshan Formation in ZG area, Tarim Basin is an important exploration target. But in this area seismic data quality is rather poor with low signal to noise ratio, high frequency absorption, and narrow bandwidth. For reservoir development, we need to improve seismic data quality of this area. To do this, we perform some well-control seismic data processing approaches in the area, such as well-control true amplitude recovery, well-control deconvolution and well-control inverse Q filtering. After the processing, amplitude is well preserved, seismic events are much more continuous, and data resolution is greatly improved. The top of Yingshan Formation is clearly described.
