Reinterpret The Seismic Data In The Xin Miao Xi

After the reprocessing of the seismic data of Xinmiaoxi and the horizontal well test,it is proved that the area has the potential of reserves.Therefore,it is urgent to re-establish the study of the combination of well and rock,to carry out the tectonic development characteristics and three-dimensional spatial distribution of the fault.In this paper,the Xinmiaoxi subject evaluation area is reconstructed and explained.Based on the results of loading the original seismic data,the combined reservoirs are specially processed to form the denoising data body,the coherent body data body,Three instantaneous attribute data body,frequency data and other seismic data.At the same time,the AC curve is normalized,the mud curve is corrected for the SP curve,and the seismic data is pretreated for reinterpretation.In this paper,the use of phase-based trapezoidal tracing technique,two-step geost ationary geostatistics inversion techniques and favorable oil and gas accumulation zone optimization techniques are used.The results show that the top 8 tectonic forms of the eight reservoirs and sandstone groups in the study area are tested and the depth of the tectonic depth is within ±3m.The total margin is 17.64 km~2,and the total trappi ng area is 17.64 km~2,with a total area of 52.93 km~2.Fine identification of broken off more than 5m,the extension of the length of more than 0.5km fault.
