Abstract: Reservoir of Ci 9 Block is a reservoir of secondary porosity and high permeability with edge water,the disadvantages of vertical well development appear more and more.Feasibility demonstrations of horizontal well development come to a conclusion that advantage is obvious of horizontal well development in this block.On the basis of remaining oil distribution regularity,development programs of horizontal well has been done by using the method of numerical simulation. The key targe layers,direction and length of horizontal section were identified and predicted the results.It turned out that horizontal well development is far better than vertical well development from the cumulative oil production and water cut rising. These provide a new direction for further development Ci 9Block.
