摘要： A coiled tubing drilling hydraulic disconnect for use in disconnecting a tool from a length of tubing or other tool string. The apparatus has an upper housing and a lower housing with a splined ring threadingly engaged with the lower housing. A spline in the splined ring engages a spline on the upper housing so that torque may be transmitted therebetween. Lugs are disposed through windows in the lower housing below the splines, and a bushing is disposed between the splined ring and the lugs. Relative rotation between the upper and lower housings causes the splined ring to tighten against the bushing and lugs, thereby eliminating play therebetween. A lug prop disposed in the upper housing may be hydraulically actuated so that the lugs may move to a disconnect position, thereby releasing the upper housing from the lower housing. Because the windows are disposed below the splines, no torque or bending are applied to the windows, and the windows and lugs are shaped to minimize stress concentrations.
