Development Effect of Horizontal Wells in Heavy-oil Reservoirs with Edge and Bottom Water in Block Lin 17of Linfanjia Oilfield

Yang Zhao-gang

Abstract

In the reservoirs with edge and bottom water,there existed the problems of bottom water coning and rapid water increase in reservoirs and serious water out.By taking Block Lin 17of Linfanjia Oilfield for example and numerical simulation,the situation of remaining oil distribution and invasion of edge water and bottom water coning are studied,horizontal wells are used for oilfield adjustment,by which the invasion of edge water the speed of coning of bottom water are slowed down,the effect of development is improved and oil recovery ratio is raised.
