Abstract

For herringbone wells with antisymmetrical and curved laterals, the effects of lateral symmetry and camber on production of herringbone wells are analyzed by semi-analytical model. The effects of laterals with different angles, different number and different spans on production of herringbone wells are analyzed on this base. The results indicate that the contribution of mainbore of production is smaller than symmetrical herringbone well whereas the contribution of laterals of antisymmetrical herringbone well is bigger. The total production of antisymmetrical herringbone well is bigger than that of symmetrical herringbone well. The curved laterals will cause less production comparing with deviated laterals. The bigger the lateral angle is the higher is production of herringbone wells. The contribution of 1/3 lateral end accounts for about 50% of the total lateral contribution. While total length of laterals is the same, the production of well with two laterals on different sides of mainbore is the highest. Besides, laterals should be put as near as possible to the middle mainbore and there is an optimum span existed.
