【摘要】 琼东南盆地深水区钻井少,影响了储层预测的准确度。为了解决这个问题,采用虚拟井技术对琼东南盆地深水区陵水凹陷南部已证实的A-1含气构造进行储层预测,验证了该方法的合理性;并总结出了A研究区内储层发育区的波阻抗经验值,据此预测相邻待钻A-2构造的储层厚度。A-2构造的预测结果与实钻结果相吻合,证实了虚拟井技术在琼东南盆地深水区勘探目标储层预测方面具有较高的可行性。更多还原

【Abstract】 There were few drill wells in Qiongdongnan basin,which affected the accuracy of reservoir prediction. In order to solve this problem,the authors applied virtual-well technique to reservoir prediction of drilled A-1 gas bearing structure in the southern part of Lingshui sag in the deep-water area of Qiongdongnan basin,which verified that the virtual-well technique is reasonable.The authors also summarized experience values of wave impedance of the reservoir in A study area.The experience values were used to predict the reservoir of A-2 structure to be drilled.The prediction of A-2 structure coincides with the drilling result,which confirmed that the virtual-well technique is of high feasibility in predicting the exploration targets in the deep-water area of Qiongdongnan basin.更多还原
