AVO技术在克拉玛依克75井区的应用效果

RESULTS OF APOLICATION OFAVO TECHNIQUE IN THE AREA OF WELL K75 IN KARAMAY

新疆首次应用ＡＶＯ技术对克拉玛依油田克７５井区的含油气范围进行了预测，其步骤是：首失根据出油气井测井的纵横波资料，建立正演这集模型；然后对实际剖面上储层顶、底界面作油层ＡＶＯ追踪，以检测两者响应是否相同；认证后再捉据此特征沿剖面追踪以确定油水边界，并预测其他可能的含油ＡＶＯ异常带。经钻井、试油资料检验，这项技术在该区的应用效果是比较理想的。

Petroliferous area in the Area of Well K75 in Karamay oilfield was first predicted with AVO technique in Xin-jiang,which was accomplished as follows:Forward trace assemblage model is established from S-wave and P-wavedata in oil well,then the top and bottom of reservoir on the actual profile are followed with AVO technique to exa-mine if both responses match well,thereafter tracing along the sections according to this characteristics to determine oil-water boundary and predict other potential oil-bearing zones witri AVO anomaly.Confirmed with driliing and testingdata,this technique is successful for use in this area.
