摘　　要：针对环县地区长8油层组试采单井产量较低、难以有效开发的问题,研究综合前人对于单井产量影响因素的认识,结合研究区实际情况,筛选出渗透率、油层厚度、砂量、井底流压等可能的单井产量影响要素,并通过这些要素与单井试油产量、试采半年产量的关系,认识到储层渗透率是影响该区长8油层组单井产量的主控因素。改善储层渗透性是提高单井产量,达到整体有效开发的关键。According to the problem that the output of chang8 formation in the Huanxian area is too low to develop effectively,studying on previous knowledge of influence factors to single well's yield,combining with actual situation,mighty influencing factors of the permeability,thickness of oil formation,quantity of sand and flowing pressure of well bottom are selected.The correlation between every elected factor and the output of chang8 formation indicates that the permeability is the most important influence factor.Developing formation permeability is the key work to improve permeability to raise the output of Chang8 formation.
