井间地震在HJ油田精细油藏描述中的应用及效果分析

The Research of the Accurate Elucidation and Effectiveness about the Cross-hole Seismic Technology in HJ Oilfield

H J油田存在砂体横向非均质性强,微小构造发育,油田采出程度低、采油速度低等问题。为进一步解决该油田的采收率问题,在工区内开展了井间地震技术试验,通过对井间地震资料储层、小断层综合解释,以及对工区储层的反演分析,指出砂体间的横向发育不连续及小断层分隔形成的小构造是造成H 73-H 49井区动态矛盾的主要原因。并且本次研究对井间地震资料的应用效果进行了分析。

There are many problem of the Huangjue Oilfield,the unhomogeneity of sand is strong,a lot of tiny structure is distributed,and the problem of low recovery percent of reserves and low rate of oil production.In order to solve the problem of low recovery percent of reserves and to enhance recovery factor,in this research,the cross-hole seismic test has been carried out in this field.Through the integrated reservoir and small fault interpretation of cross-hole seismic data,and after the research of the seismic inversion,we found that the cross discontinuity of the sand and the microtectonics by the minor fault are the main reason of the dynamic problem in Huang73-Huang49 well area.And last,we do some analysis of the effectiveness of the cross-hole seismic technology.
