| Nowadays,the structural reservoirs have been almost developed completely,as a complex reservoir,volcanic rock has great development potential,the volcanic rock reservoir has been increasingly on its way to the top of discussion and study.In the process of the prediction of volcanic rock reservoirs,seismic inversion and fluid detection are two key techniques,in which the reservoir prediction based on the post-stack inversion is the basis of the identification of traps,and the fluid detection technology is the key to identify the potential of the trap and the distribution of oil and gas.Aiming at carboniferous volcanic rock reservoirs in Karamay Zhongguai Salient area,this paper analyzes the lithological features of the volcanic rock reservoir,with the basis of fine seismic interpretation,in order to finely describe and evaluate volcanic rock reservoirs using post-stack seismic inversion and fluid detection technology,then analyzes structure,deposition,reservoir and fluid characteristics of volcanic rocks comprehensively to establish a proper and appropriate method for seismic reservoir prediction of volcanic rocks.At last,the method is applied to the actual data area in Karamay Zhongguai Salient.Through the analysis of the drilled well,the reservoir forming conditions of carboniferous volcanic rock reservoirs are summarized,finally the favorable target evaluation of volcanic rock reservoirs in the study area is realized. |
