Annotation:

When drilling inclined and horizontal wells, there occurs a pressing problem of a drill string sticking in the open wellbore during round trip operations (RTO). Sticking during a drill string movement in the open wellbore is characterized by suddenness and unpredictability, associated with the uncertainty of the intervals sticking danger in the form of sharp and local curvatures of the wellbore, displacements and ledges in a borehole wall, which are not detected by standard measuring devices. This factor is superimposed by changes of the borehole shape and condition during chemical-mechanical impact of drilling mud on rocks and the drill string during drilling and RTO. Analysis of the drilling technology by applying devices of geological and technological control allows establishing points and intervals along the borehole with defects in the form of local curvatures, ledges and displacements. A BHA, including support and centering elements, is the tool which can make it possible to determine potentially sticking-hazardous intervals complicated by local curvatures and ledges in the borehole wall. The authors of the article propose to identify critical sticking intervals based on a multivariate analysis of the BHA interaction of with the wellbore during drilling and RTO operations based on the data of geological-technological studies. One example of a drill string sticking after reaching the design drilling depth of the horizontal section of the well sidetrack at the Priobskoye field in the Western Siberia is considered in the article as well.
