| Abstract: | Seven typical productivity formulas of branched horizontal well are analyzed in this paper.It is found that WANG Wei-hong's formula and LI Dang's formula are the special cases of CHENG Lin-song's formula,and JIANG Ting-xue's formula is more accurate than CHENG Linsong's formula.The important breakthrough in external seepage resistance made by QI Cheng-wei is verified through theoretical analysis and case calculation.Further analysis shows that the external seepage resistance made by QI Cheng-wei is self-compatible and rigorous.Finally,a complete productivity formula is presented,in which various additional resistances are taken into account. |
