摘要
针对薄储层预测、砂体相变线识别这一岩性油气藏描述的关键点,在深入分析玉东地区薄储层预测地震地质难点和技术现状的基础上,提出针对该区的薄储层预测技术思路,即利用重新处理的三维地震资料,联合应用地震子波分解与重构技术、地层切片技术以及基于拟波组抗的地震波波形指示反演技术,同时井震结合,重新预测古近系3砂组砂岩空间展布,并结合钻井和构造刻画了古近系3砂组岩性气藏平面展布形态,预测了新增储量规模。
In view of thin reservoir prediction and sand body facies line identification,which are the key points of lithologic reservoir description,based on the in-depth analysis of the seismic and geological difficulties and technical status of thin reservoir prediction in Yudong area,the technical ideas of thin reservoir prediction in this area are put forward.That is to say,by using the reprocessed 3D seismic data,combining with the seismic wavelet decomposition and reconstruction technology,stratigraphic slicing technology and seismic waveform indication inversion technology based on quasi-wave group resistance,and combined with the well and seismic data,the spatial distribution of sandstone in Paleogene 3 sand formation is predicted again.In combination with drilling and structure,the plane distribution of lithologic gas reservoir in Paleogene 3 sand formation is characterized,and the scale of new reserves is predicted.
