Abstract:The horizontal well H024U is used to connect the first and the second target-vertical well V024 and V024U.The advanced construction technology of brine mining connection well and the magnetic measurement guiding system with high technology content independent intellectual property right manufactured by the Institute of Exploration Techniques(achievement of geological investigation project) were adopted in the construction.Based on the construction experience of horizontal wells in Turkey,the drilling parameters were carefully designed and controlled,accurate target hitting was realized with hitting the production casing bottom of V024U to realize the accurate well connection.
Keywords:directional butted wells  trajectory adjustment  accurate target hitting by magnetic measurement
