Research On The Cluster Well Crash-proof Design And Construction Method

With the increasingly tight oil and gas resources,the application of cluster drilling technology can not only reduce the cost of relocation,but also effectively improve the recovery rate of low efficiency oil and gas wells.With the offshore oil and gas fields,low permeability oil and gas fields and the old oil and gas fields of the encrypted mining,cluster wells in the field of drilling applications become more and more widely.Due to the close distance between the adjacent wells in the construction process,if unreasonable design,may lead to very serious engineering accidents.Therefore,it is very important to improve the success rate of collision prevention and control of cluster wells,which can effectively reduce engineering accidents and save drilling costs.Selected according to different depth structure,reasonable crash-proof scanning calculation method,and application of scanning parameters crash-proof scanning software to map out the touch,which can determine the adjacent Wells contrast(well)and is drilling the shortest distance between well(target),to determine whether the risk of collision,and then make a reasonable preventive measures.In order to improve the success rate of the boring wells and reduce the difficulty of drilling and the total cost of drilling,the anti-collision work must be carried out in the drilling cycle.In this paper,we focus on the optimization of the orbital parameters of the cluster wells,and from the aspects of selecting the oblique point,the slope of the slope and the type of the track,the layout and optimization are optimized to achieve the goal of improving the success rate of the cluster.
