Wellhead Arranged Method of Cluster Well Pad

In order to optimize the design of cluster wells further,the optimization and allocation of wellheads and targets on well pad had been investigated.If the wellhead in multiple rows and columns was uneven,first the wellheads and targets were divided with straight line or concentric circles,then based on the principle that the wellheads and the target connections do not intersect on horizontal projection and the minimum sum of horizontal displacement square called "disjoint and minimum distance method",the corresponding mathematical model and calculation software had been set up.Taking the cluster wells in Jilin Oilfield as example,the optimal wellhead-target distribution was worked out quickly by this calculation software,proving that the proposed method by the author could get the optimal wellhead-target distribution results fast,enhancing the efficiency of designers.
