Abstract: In recent years the multilateral horizontal well plays a more and more important role in the development of low permeability oil and gas reservoir, which is the effective method to exploit shale reservoir and tight sandstone reservoir. In order to further improve the yield, hydraulic fracturing cracks could be used to increase oil and gas production of multilateral horizontal well. Based on the water and electricity resembling principle, the experiment inspected the crack length, osmotic conditions，branch number, the influence of horizontal segment of the openhole and closed conditions. The results show that there existed the optimal length of cracks and the yield of each branch horizontal well was different|there existed yield differences between openhole completion and closure completion under the conditions of the same branch.

Key words: Fractured multilateral horizontal well, Electrolytic simulation experiment, Crack length, Osmotic conditions, Number of branch, Well completion condition
