海上深水区气枪震源阵列优化组合研究与应用
A study on optimization of seismic air-gun array source and its application in offshore deep water
【摘要】 基于海上气枪震源子波模拟方法,对海上多子阵不同气枪阵列组合的震源子波进行了大量的模拟试算,提出了适应海上深水区地震勘探要求的多子阵立体阵列组合方式和2种平面阵列优化组合模式,并对优选的立体四子阵列和平面六子阵列组合震源进行了不同勘探靶区野外地震采集试验,取得了良好的应用效果。
【Abstract】 A lot of pilot calculations of simulation were conducted for the wavelets from various offshore air-gun array sources with multiple sub-arrays,by using the method of simulating these wavelets,and some optimized options of air-gun array source were developed,which are suitable for the seismic survey in offshore deep water,including the stereo-array source with multiple sub-arrays and two types of planar-array source.Two optimized array sources,i.e.a stereo-array source with four sub-arrays and a planar-array source with six sub-arrays,have been used in seismic acquisition tests in different deep-water areas,and their effects are quite good.
【Key words】 air-gun source; stereo-array; planar-array; optimization; seismic acquisition test; deep-water area;
