Description
One, technical field
The utility model relates to oil drilling, operation aid technology, particularly is a kind of drilling well autocompensation installation.
Two, background technology
At present, in drilling well, operation drilling construction, utilize helicoid hydraulic motor, when drill bit creeps into,, need the frequent tubing string of transferring to creep into owing to creep into the requirement of the pressure of the drill.Cause labor intensity of operating staff big, the pressure of the drill control is inaccurate, and drilling efficiency is low.Prior art can not solve the problems of the technologies described above preferably.
Three, summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of drilling well autocompensation installation is provided.
Above-mentioned purpose is achieved through the following technical solutions:
The drilling well autocompensation installation comprises: top connection, abutment sleeve, sliding sleeve, slideway, upward short circuit, piston, piston sleeve, short circuit, lower contact down; Its integral body is columnar structured, abutment sleeve and piston sleeve are one, abutment sleeve is positioned at top, with be provided with the box thread top connection and be threaded, top connection upper end box thread is used for jointed rod, piston sleeve is positioned at the bottom, being provided with the cross section in the abutment sleeve is dolioform slideway, in case sliding sleeve rotates, the slideway bottom is a plunger shaft, and the bottom of plunger shaft is the short circuit through hole less than the plunger shaft diameter, sliding sleeve is installed in the slideway, can slide up and down, sliding sleeve is threaded with the upper end of last short circuit, and the lower end of last short circuit is threaded with the upper end of piston, piston is installed in the plunger shaft of piston sleeve, can slide up and down equally, the lower end of piston is threaded with the upper end of following short circuit, and the lower end of following short circuit is threaded with lower contact, the lower contact lower end is provided with male thread, with drilling rod, drill bit connects, and is provided with centre bore from sliding sleeve to lower contact, so that drilling fluid is passed through.
The beneficial effects of the utility model are: simple in structure, easy to operate, safe and reliable, alleviate post operation personnel's labour intensity, and the pressure of the drill precise control has the automatic drill effect of repaying of nourishing, and improves drill footage, and the drilling efficiency height reduces drilling well, operating cost.
Four, description of drawings

Fig. 2-A-A view of the present utility model.
In the accompanying drawing, 1-top connection, 2-abutment sleeve, 3-sliding sleeve, 4-slideway, the last short circuit of 5-, 6-plunger shaft, 7-piston, 8-piston sleeve, short circuit under the 9-, 10-short circuit through hole, 11-lower contact, 12-centre bore.
Five, the specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
The utility model comprises: top connection 1, abutment sleeve 2, sliding sleeve 3, slideway 4, upward short circuit 5, piston 7, piston sleeve 8, short circuit 9, lower contact 11 down; Its integral body is columnar structured, abutment sleeve 2 is an one with piston sleeve 8, abutment sleeve 2 is positioned at top, with be provided with box thread top connection 1 and be threaded, piston sleeve 8 is positioned at the bottom, being provided with the cross section in the abutment sleeve 2 is dolioform slideway 4, slideway 4 bottoms are plunger shaft 6, the bottom of plunger shaft 6 is the short circuit through holes 10 less than plunger shaft 6 diameters, sliding sleeve 3 is installed in the slideway 4, sliding sleeve 3 is threaded with the upper end of last short circuit 5, and the lower end of last short circuit 5 is threaded with the upper end of piston 7, and piston 7 is installed in the plunger shaft 6 of piston sleeve 8, the lower end of piston 7 is threaded with the upper end of following short circuit 9, the lower end of following short circuit 9 is threaded with lower contact 11, and lower contact 11 lower ends are provided with male thread, and 11 are provided with centre bore 12 from sliding sleeve 3 to lower contact.
Operating principle: the drilling well autocompensation installation is installed on the required drill string weight of control the pressure of the drill, and when drilling well, sliding sleeve 3, piston 7 slide in abutment sleeve 2 and piston sleeve 8 with following short circuit 9, can carry out axial stretching.Drill bit is met to bottom or plug face, transfers tubing string, and sliding sleeve 3, piston 7 take in the sleeve with following short circuit 9, stop to transfer tubing string, and drill bit creeps under this device lower drilling string weight effect; Outside sliding sleeve 3, piston 7 and following short circuit 9 were stretched out piston sleeve 8 simultaneously, distance was crept in compensation, realizes creeping into automatically.
