一个被开发证实的隐蔽油气藏解释实例

寻找隐蔽油气藏已经成为人们最关注的热点之一。一年前,作者曾经利用形成“储层演化地震分析”模式的技术思路,对塔里木盆地北缘一个油田的隐蔽油气藏开发实例进行了深入研究。这套技术思路是：首先采用基于相对保持振幅和波形的提高分辨率处理然后在基于参考标准层井信息标定基础上沿参考标准是进行地震属性提取,最后通过地震属性的空间变化识别厚度小于1/4波长的薄储层,该隐蔽油气藏经过一年多的开发后结果表明,现今的开发区域和当初提供的地震振幅异常预测分布范围十分吻合。此例说明作者总结的“储层演化地震分析”解释方法在寻找隐蔽油气藏领域有广阔的应用前景。

Interpretation case:a being development-proved concealed oil/gas reservoir.

Looking for concealed oil/gas reservoir is becoming one of hot-points of most interest by the people. A year ago, the author used the technical idea forming the mode of " seismic analysis by reservoir evolution" to deeply study the development case of concealed oil/gas reservoir in a oilfield of northern Tarim basin. The set of technical ideas is:first,adopting the processing of improving resolution based on amplitude and waveform preservation; then, picking up seismic attributes along referential markers on a basis of conducting well information labeling for referential markers ; finally , the thin reservoir the thickness is less than 1/4 wavelength being identified by spatial changes of seismic attributes. It is proved after over one year's development of the concealed oil/gas reservoir that the currently developed areas coincided similarly with distributed areas of predicted seismic amplitude anomaly provided before, which proved the author-summed-up interpretation method of "seismic analysis by reservoir evolution" has broad application prospect for exploration of concealed oil/ gas reservoir.
