Completion technology of Lin4 ping2 well

A new completion well method is applied in Lin4 ping2 horizontal well at first time,the method is make up of slotted screen with external casing packer.The hole trajectory of Lin4 ping2 well is wavilness,and the formation drilled was composed of much mudstone.A axial slotted screen was selected as a tool avoid sloughing accidents,the slotted screen had slot width 0.3 mm,slot length 80 mm,space between slot 30 mm and slot consistency 40.In order to avoid formation and screen pipe plugging caused by filter cake,slotted screen with external casing packer completion string and acid cleaning inflate packer string were designed,could isolate two sets of no main hydrocarbon source rock.The well maximum oil production is 42 t/d,is seven times of vertical well.Provide experiment for drilling horizontal well of sandstone reservoir in Huabei Oilfield.
