反演技术在喇嘛甸油田储层预测中的应用
|
摘要
地震反演技术在岩性油气藏勘探开发中发挥着越来越重要的作用。以叠后地质统计学反演方法为依托,重点论述了构造建模、测井曲线一致性校正、井震标定及子波提取和变差函数等关键技术;并以喇嘛甸油田A区为研究对象,对最终反演结果——砂岩概率体进行分析。结果显示:反演结果具有较高的分辨能力,而且与测井解释结果符合程度也很高,尤其是在对薄储层、厚储层及断层的显示方面。该次研究采用的叠后地质统计学反演方法具有非常独特的优势,能指示河道砂体发育情况,可以指导井位部署。
Seismic inversion in lithologic reservoir exploration and development played an increasingly important role.By using post-stack geostatistical inversion method as a basis,the fault structure modeling,correction caused by logs,wells and seismic wavelet extraction and calibration variogram and other key technologies were emphatically denoted.By taking A area of Lamadian Oilfields for example,the final inversion result-sandstone body probability was analyzed.The results show that the inversion results have a higher resolution,and it had high coincidence rate with logging interpretation results,especially in the thin and thick reservoir and display of the fault.The study used post-stack geostatistical inversion method has a very unique advantage,can indicate the development of channel sand,can guide the well position deployment.
