从最大经济效益角度出发,一般为降低投入而减少钻井,降低井网密度,由于低渗透储层连通性差、渗流阻力大,井网太稀,井距太大,油井很难见到注水效果,开发效果差,采油速度和最终采收率都很低,所以对低渗透储层油田的开发效果影响很大。本文主要探讨SAN技术在胡尖山油田勘探开发中的应用。 From the point of view of maximum economic efficiency, it is common to reduce drilling volume and well pattern density to reduce investment. Due to poor connectivity of low-permeability reservoirs, large seepage resistance, too thin well pattern and large well spacing, it is very difficult for the well to see the water injection effect. Development of poor results, recovery rate and the ultimate recovery rate is very low, so the development of low permeability reservoir oil has a great impact. This paper mainly discusses the SAN technology in the exploration and development of the Jiushan oil field.
