铜锣峡构造中南段长兴组裂缝性储层综合预测

Integrate prediction of fractured reservoir with carbonate rock in Changxing Group in mid-south section of Tongluoxia Structure

铜锣峡构造长兴组储层为碳酸盐岩裂缝性储层 ,由于该储层的非均质性较强 ,地震资料的品质较差 ,因而对其预测的难度较大。目前 ,虽然采用了先进的地震处理技术 ,但储层预测的效果仍不突出 ,关键的问题是现有的地震处理技术对裂缝的预测精度较差。对铜锣峡构造中南段长兴组储层预测研究发现 ,应用地震速度反演、常规剖面解释及构造应力场有限元模拟等方法进行综合识别 ,可以大大提高储层的预测精度。这是储层预测的一种有效方法 ,特别适合于勘探较早的地区。

In the area of the Tongluoxia Structure,the reservoir of the Changxing Group belongs to the fractured reservoir with carbonate rock.Because of obvious heterogeneity of reservoir and poor quality of seismogram,it is very difficult to predict this type of reservoir.At present,though the advanced techniques of seismic interpretation have been adapted,the prediction effect is still imperfect.The existing techniques of seismic interpretation are not suitable for predicting the fractures of reservoirs.The prediction of fractured reservoir with carbonate rock in the Changxing Group in the mid-south section of the Tongluoxia Structure showed that the prediction precision has been improved outstandingly with the integrate prediction of seismic velocity inversion,explanation of seismic section and limited-cell simulation of structure-stress methods.This method particularly suits for predicting reservoir of the earlier explored district.
