水平井技术在红花套低渗底水油藏中的应用研究

低渗透底水油藏的开发过程中,如何抑制底水的突进,提高油藏最终采收率,是油藏及地质人员所面对的一个较为普遍的难题。松滋油田复I断块红花套组油藏属于典型的低渗透底水油藏,综合构造、储层、流体性质、油水界面关系等研究成果,油藏具有油层厚度大、纵向上油层较多的特点。随着水平井技术的日臻完善,水平井开发技术在国内外都已经由研究探索阶段发展到成熟应用阶段,为油藏及地质人员提供了更为广阔的思路。在该油藏的高部位规模性地应用水平井,并取得了较好的效果,有效地抑制了底水的突进,储量得到合理的动用,油田实现持续高效开发,采收率水平得到进一步提高,为该油田的稳产打下了坚实的基础。

Applications of Horizontal Technique in low permeability reservoir with Bottom Water of Honghuatao Oil-field

Low permeability bottom water reservoir development process,how to suppress the end of the onrush of water,increase ultimate recovery reservoir,the reservoir and geological personnel are facing a more general problem.Safflower oil complex I Songzi block kit typical of low-permeability reservoir bottom water reservoir,integrated structure,reservoir,fluid nature of the relationship between oil-water interface of research results,a large reservoir with the reservoir thickness,reservoir than vertical more features.With the horizontal well technology is improving,horizontal wells have been made by technologies at home and abroad to explore phases of application development to a mature stage,the reservoir and provide a wider geological ideas.In the high parts of the reservoir scale application of horizontal wells,and have achieved good results,effectively inhibited the penetration of water into the bottom,the use of reasonable reserves,to achieve sustainable and efficient development of oil fields,to further improve the level of recovery,stable for the field to lay a solid foundation.
