摘要
珠一坳陷共分布着10个生烃凹陷,其中4个已被证实为富烃凹陷,其余的潜在富烃凹陷的规模和潜在资源量并不亚于已证实凹陷,但由于以往采集的中深层地震资料品质不佳,严重制约了对潜力富烃凹陷的评价和认识。为了实现勘探认识和勘探潜力上的新突破,从地震资料存在的问题入手,针对凹陷的埋深和构造特点,对地震采集参数做出了一系列分析和改进,取得了相比老资料更好的采集效果,为凹陷评价工作提供了更有说服力的证据。同时,针对采集处理效果,进行了分析评价,提出了进一步改善的建议。
In Zhu 1Depression,there existed 10source depressions,of which 4was proven to be hydrocarbon enriched depressions,the rest of them were potentialized hydrocarbon enriched depressions,their scales and source extent were more than those of the proven ones,but because of the poor quality of the data collected from mid-deep reservoirs,is severely restricted the evaluation and understanding of the hydrocarbon enriched depressions.To implement the understanding of oil exploration and bring the breakthrough of exploration potential and in consideration of the problem existed in seismic data and the characteristics of the buried depth and structural characters of the depressions,the collected data are systematically analyzed and improved,effect which is better than that of the data is obtained,which provides strong evidence for evaluation.Suggestion is given for further improvement based on the effect of data acquisition.
