番禺低隆起~白云凹陷北坡地区是珠江口盆地最有利的油气勘探区域之一,目前已经发现了PY30-1、PY34-1、PY35-2、PY35-1和LH19-5等五个气田,天然气地质储量达1 200×108m3。如何在现有的勘探成果基础上进一步拓展勘探领域,对珠江口盆地东部天然气勘探的持续发展有着重要的意义。这里在依托番禺低隆起三维地震资料的前提下,以钻井、测井、地震等原始资料为基础,对本区的岩性电性特征进行分析,进而确定储层含气后在地震属性、AVO、瞬时子波吸收、波阻抗等资料上的响应特征,从而综合运用属性、子波吸收、AVO、反演、圈闭保存条件等多种手段,对目标圈闭的含油气性及储层进行预测。
The Pulau uplift ~ the northern slope of Baiyun sag is one of the most favorable oil and gas exploration areas in the Pearl River Mouth Basin. Five gas fields, PY30-1, PY34-1, PY35-2, PY35-1 and LH19-5, have been discovered. Natural gas geological reserves of 1 200 × 108m3. How to further expand the exploration field based on the existing exploration results is of great significance to the sustainable development of natural gas exploration in the east of the Pearl River Mouth Basin. Based on the three-dimensional seismic data of low uplift in Panyu, based on the original data of drilling, logging and earthquakes, the lithological electrical characteristics in this area are analyzed to determine the seismic attribute, AVO, Instantaneous wavelet absorption, wave impedance and other data on the response characteristics, and thus comprehensive use of property, wavelet absorption, AVO, inversion, trap preservation conditions and other means, the target trap of oil and gas and reservoir prediction .
