Ordos Basin West Margin Land Acquisition Technology Research Before Area

Ordos west margin foreland basin is very rich in oil and gas resources, and has already become changqing oil field exploration key areas, but the piedmont region with high and steep rock the exposed or the thick gravel layer covering, the surface rolling and so on in the complex surface condition, thrust and the pushover overthrust such complex geological structure development speed, underground dramatic changes in horizontal and other reasons, cause material is rare, and material signal-to-noise ratio is low, continuity is poor. Through the exploration in west margin in recent years because of land acquisition technology innovation area before the summary, found a suitable for complicated structure area of exploration collection technology, using JianBiaoCeng lithology survey of surface model, using the forward modeling design flexible observation system, in the time domain, the space domain high density sampling, amplified by point design inspired deep Wells, optimizing the triggers, cooperate with more mature the seismic data processing technology (more method combined static correction, multiple domain denoising, prestack time migration), get to meet the exploration of construction material, while the increase in oilfield company to make new contribution amount.
