Abstract


Branch horizontal well technology is one of the emerging technologies for the oil industry , oil and gas field development , an important way to enhance oil recovery . Numerical simulation technology as a quantitative description of the analytical tools optimized branch horizontal well type and stratigraphic adaptive parameter screening provides a theoretical basis and experimental tools . This paper, the use of numerical reservoir simulation software Eclipse the simulation described fishbone branch horizontal wells . First , analyze the percolation characteristics of fish bones well , including the formation pressure distribution and the main the branch wellbore pressure and flow distribution . On this basis , the parameters that affect the type of fish bones wells optimized angle increases with the number of branches , branching , spacing and branching , fish bone well production also increases , but the parameter increases the yield contribution becomes smaller, from the economic point of presence of the optimal number of branches , the branch spacing and branch angles ; other parameters under certain conditions , branch interleaved distribution than symmetric distribution effect . Next, further analysis of the impact of fish bones well productivity factors , including the anisotropy of the formation as well as the different rhythmic strata differentials and other factors ; and the vertical position of the fish bone well optimized , the vertical position of principle on a fish bone well to stay away from the oil-water interface . Using orthogonal design further analysis to verify the sensitivity of the different parameters . Fish bone Well Network is a simple analysis of screening and vertical wells compared the use of fish bone oil wells is the effect of waterflood with horizontal wells to water injection .
