Abstract

Fishbone shaped multilateral wells have such advantages as large contact area with productive formation and high production.In the lateral period of gas reservoir exploitation,the flow resistance may increase sharply due to water production,so precise prediction of the productivity of wells will be essential.Based on the rule of two-phase flow of gas and water,considering the threshold pressure gradient,stress sensitivity,angle between branch and the main wellbore,slippage effect,the influence of the high speed non-Darcy effect,and skin factor,using conformal mapping and law of equivalence percolation resistance,the formula for calculating productivity of a fishbone multilateral wells has been derived.Through case study,with the increase of angle between branch and the main wellbore,the number of branches,the production will increase|with the increase of the threshold pressure gradient,the factor of stress sensitivity,and WGR,the production will decrease.This study provides a certain extent for predicting the productivity of fishbone shaped multilateral wells while producing water.
