Abstract

In the latest years, the studies on steady-state productivity theory for horizontal wells are more and more mature. Steady-state productivity formulas for horizontal wells in different methods emerge as the times require, but not all of the formulas can be used to predict the productivity of horizontal well accurately, so the logical choice of
productivity formula is of great importance. Based on the pseudo-three-dimensional method, conformal mapping method and other related methods, this paper summarized the research progress of productivity theory for conventional horizontal wells all over the world, and made an applicability analysis of all the formulas by examples. The analysis result shows that if the reservoir type is the same with that shown in this paper, the formulas of Borisov （Lang Zhaoxin）, Giger, Renard-Dupuy (Guo Xiao and Li Zhenxiang), Fuirui and Chen Yuanqian are practical in predicting theproductivity in the field. The study can provide theoretical basis for choosing formula in reservoir devel opment reasonably.
