摘要: A well has a vertical casing with window, and lateral wellbore which communicates the may have or liner. window assembly aligned respective passageways for first second tubing strings, concave surface deflecting string out into wellbore. The passageway portion is inclined at very small angle respect to centerline of casing. As run casing, rotational locator releasably coupled thereto by soft release coupling mechanism. After effects orientation, mechanism released then permits move therepast without damage. seal on covered protective sleeve as it inserted well, exits after entering
