WebMar 28, 2024 · In inclined holes drillpipe weight can be placed on the drill bit because complete helical buckling of the drillpipe is delayed by the effort required to lift the drillpipe to the high side of the hole. Once the axial load in the drillpipe exceeds its critical buckling load the drillpipe will buckle in an "lazy S". This type of buckling is not bad. WebConsequently, a straight inclined hole is preferable to a nearly vertical crooked hole containing numerous dog-legs. In this paper, theories of the cause of hole deviation and analyses of drill string behavior under down-hole conditions are summarized.
