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。
There are 10 hydrocarbon-generating depressions in Zhu-1 depression, of which 4 have been confirmed as hydrocarbon-rich depressions. The remaining potential hydrocarbon-rich depressions have the same size and potential resources as the confirmed depressions. However, The quality of deep seismic data is poor, which severely restricts the evaluation and understanding of potential hydrocarbon-rich depressions. In order to realize the exploration breakthrough and potential exploration breakthrough, starting with the problems of seismic data, a series of analysis and improvement of seismic acquisition parameters are made according to the depth and structural features of the depression. The collection results provide more convincing evidence for the evaluation of the depression. At the same time, according to the collection and processing effect, the paper analyzes and evaluates and puts forward suggestions for further improvement.
