川西岩性气藏地震勘探关键技术研究
|
摘要
三维地震勘探是支撑川西地区岩性气藏储层预测和井位部署的关键技术。通过对川西拗陷侏罗系岩性气藏勘探地震采集、处理、解释、储层及流体预测5个方面的研究,研制、总结了采集设计和野外质量控制的2个关键环节,做好保幅处理,坚持"整体、自动、精细"3个基本解释准则,储层预测中依靠振幅资料,流体预测中充分利用频率和吸收参数等物探关键技术和控制点。这些技术在10个地区进行了推广应用,部署并实施了勘探开发井60余口,支撑了约500×108 m3探明储量的提交。
The 3D seismic exploration is the key technologies to support lithologic gas reservoir prediction and well deployment in west Sichuan. Through the research of seismic acquisition,processing,interpretation,reservoir and fluid prediction of Jurassic lithologic gas reservoir exploration in west Sichuan depression,a suit of key technology is summed up,that is,in seismic data acquisition,the key is good design and quality control;in processing,the key is to preserve amplitude processing;in interpretation,the key is to insist"whole,automatically,fine"three basic criteria;the reservoir prediction relies on the amplitude information,and flow forecast makes full use of parameters of frequency and absorption. These technologies are carried out in 10 districts,deploying more than 60 exploration and development wells,and submitting proven reserves of about 500 billion cubic. Further more,these technologies are also an important reference for the exploration of dense clastic rock gas reservoir that widely distributed in China.
