为适应新的油气勘探形势要求,应进一步加强4个方面工作:①有必要进一步提高地震勘探的分辨率,为此, 应继续把做好静校正作为提高分辨率的关键工作来抓;做好沙漠区沙丘对地震波的吸收衰减补偿工作;从资料处理角度重视做好沙漠区激发子波分析,并实现确定性子波反褶积,保幅处理要坚持同时实现时间域-频率域保幅处理; 进一步提高分辨率采集研究。②重视加强三维工区速度资料的研究,深化三维资料区速度研究,做好速度分析研究工作。③加强山前地震攻关研究。④做好地层-岩性类隐蔽油气藏的识别难题,隐蔽圈闭研究有10大难题。为此,有必要进一步提高地层-岩性类复合型隐蔽油气藏的识别描述水平,必须切实做好3项基础工作,必须为圈闭识别和储层预测描述提供应有的资料成果,必须做好精细的速度研究和变速成像技术,必须提交迭前时间偏移成像剖面。
In order to meet the requirements of the new oil and gas exploration situation, we should further strengthen the work in four aspects: ① It is necessary to further improve the resolution of seismic exploration. Therefore, we should continue to do the static correction as the key task to improve the resolution; From the perspective of data processing, the analysis of excitatory wavelets in the desert area should be done well, and the deterministic wavelet deconvolution should be implemented. The amplitude preserving processing should adhere to the simultaneous time-frequency amplitude preserving processing; Further improve resolution acquisition research. ② emphasis on strengthening the three-dimensional work area speed data research, deepen the three-dimensional data area speed research, do a good job of speed analysis and research. ③ strengthen piedmont earthquake research. ④ Well stratigraphic-lithologic subtle reservoir identification problems, hidden trap research has 10 major problems. Therefore, it is necessary to further improve the identification and description of the stratigraphic-lithologic complex subtle reservoirs. Three basic work must be done in an earnest manner, and the necessary information and results must be provided for trapping identification and reservoir prediction description. Fine-grained speed studies and variable-speed imaging techniques must submit a prestack time migration imaging profile.
