摘要
目前,国内外许多学者对水平井产能作了大量的研究,然而,利用前人推导的水平井产能公式计算窄条状油田的水平井产能误差较大,无法合理预测该类型油田的水平井产能。利用镜像反映和势叠加原理等渗流理论,推导了窄条状油田的水平井产能公式,并与现场实际产量进行对比,相对误差小于10%。本文的结果对水平井在窄条状型油田开发中的实际应用提供了理论基础。
Nowadays,the productivity of horizontal well has been studied by many scholars,and the productivity formulas of horizontal well are derived. It is the typical productivity formulas of horizontal well in infinite reservoir by scholars,such as Joshi,Giger,Borisov,Renard. However,the productivity of horizontal well in narrow channel sand reservoir has not been studied,and it is necessary to be further studied. Based on the theories of mirror image method and superposition principle,the production behaviors of horizontal well in narrow channel sand reservoir are studied,and the productivity formulas of horizontal well are derived. Filed applications show that the relative error between practical and calculated value is less than 10%,and the calculation result is accurate. The results of this paper may provide the theoretical basis for the practical application of horizontal well in oil development.
