摘要

贝中区N1 段油层较薄、物性较差,为提高单井产量、改善油藏动用程度、增大井筒与油层接触面积,该区开展了水平井试验研究。文中分析了N1 段油层地质特征,探讨了油藏开发水平井的可行性,并结合典型井希3-平1 井分析了N1 段水平井的开发生产情况。N1 段水平井开发生产试验结果表明,水平井产量为周围直井的3~4 倍,达到了预期效果,为进一步在该段油层开发水平井提供了依据。

Abstract

The reservoir of N1 section in Beizhong block is characterized by thin reservoir and poor physical properties. The experimental study of horizontal wells is carried out in order to raise the individual well production, to improve the used level of the reservoir, and to increase the contact area of the bore hole with oil layer. The geologic features of N1 section are analyzed, and the practicability of horizontal well development is discussed. Combined with the typical Xi 3- Ping 1 well, the development and production of horizontal well in N1 section are analyzed. The result shows that the output of a horizontal well is 3 to 4 times higher than the vertical well around, which provides foundation for the further development of horizontal wells.
