Optimal Design Method of Side Drilling Track in Bohai Oilfield
The use of sidetracking in old wells in Bohai Oilfield can realize the economical and effective development of remaining oil in old oilfields.The design of sidetracking track determines the risk of collision prevention,the abandonment process of old wellbore,the structure of sidetracking body,etc.How to choose the optimal sidetracking track critical.Based on the design criteria of safety,economy and efficiency,this paper proposes a sidetrack design method of"well location matching + bottom-up sidetracking point optimization"in Bohai Oilfield,which is applied to the drilling and completion design of a Bohai Oilfield.The results show that this method can reduce the risk of track collision prevention,control the risk of well control,reduce the cost by more than 1 million yuan,and can meet all the needs of geological reservoirs.Under the premise of satisfying safety,this method can greatly improve the economy of sidetracking and the efficiency of scheme design,which provides a new idea for the design of sidetracking track in Bohai Oilfield.
