    • Methods for wellbore operations in an earth wellbore with tubing within casing in an earth wellbore, the wellbore extending down into earth from an earth surface, the tubing including a tubing string with a lower end and extending down within the casing with the lower end at a point above a lower end of the casing, a tubing-casing annulus between the tubing and the casing sealed by a first sealing apparatus, the method including sealing the lower end of the tubing string with a sealing device to prevent fluid flow therethrough, and sealing the tubing casing annulus with a second sealing apparatus above and spaced apart from the first sealing apparatus. In certain aspects the sealing apparatuses provide upper and lower spaced-apart primary barriers. The methods in additional aspects include making an exit opening through the tubing and an exit opening through the casing, each exit opening located between the first sealing apparatus and the second sealing apparatus. In other aspects the methods include drilling a lateral wellbore from the exit opening through the casing. Apparatus is disclosed that is useful in such methods.
    • 井筒内的井眼操作方法,井筒内的管道中的管道,井筒从地球表面向下延伸到地下,管道包括具有下端并在壳体内向下延伸的管柱,下端处于 在套管的下端上方,由第一密封装置密封的管和壳体之间的管壳环形空间,该方法包括用密封装置密封管柱的下端以防止流体流过其中,并且密封 所述管壳套管具有在第一密封装置上方并与第一密封装置间隔开的第二密封装置。 在某些方面,密封装置提供上部和下部间隔开的主要屏障。 在另外方面的方法包括通过管道形成出口和通过壳体的出口,每个出口位于第一密封装置和第二密封装置之间。 在其它方面,所述方法包括从出口通过壳体钻出侧井筒。 公开了在这种方法中有用的装置。
