Described axial locking mechanism comprises the pin that was fixed on the liquid main body inner wall, is distributed in head tank, Lower tank on the outer wall of inner tube along circle alternate, on outer wall of inner tube, also be provided with the rotation transposition gathering sill that is oppositely arranged with high Lower tank, the junction of described high and low position groove is two groups of relative inclined-plane teeth that tilt in the same way with the junction of each rotation transposition gathering sill, and the crown of every group of inclined-plane tooth is all on the inclined-plane that axially aligns another group inclined-plane tooth.
Described axial locking mechanism comprises that also elasticity was connected in the spring that is used for the coupling mechanism force answer between liquid main body and the interior pipe.
Be provided with sealing ring in the both sides of interior pipe liquid pass hole on the outer wall of pipe in described, the outer wall of interior pipe and the pressure measurement liquid pass hole of crossing the liquid main body correspondence position both sides under mated condition not are set with sealing ring.
The upper/lower terminal of described urceolus is fixed with upper and lower joint.
On the described inwall of going up the last positioning pipe that locating slot is located in the urceolus to be connected.
The pipe lower end guide pipe that is connected down in described, described time locating slot is located at down on the guide pipe inwall, and the end opening of following guide pipe is the little enlarging of outer imperial palace.
Have locating slot in the direct-reading delaminating pressure testing seating nipple of the present invention, after dropping into the down-hole, the direct-reading delamination pressure gauge can accurately be located cooperation according to the position of locating slot, realizes the pressure measurement of random layer; Because the axial bridge-type flow channels in the liquid main body is walked around liquid pass hole radially excessively, both do not communicate, therefore oil reservoir to be measured right liquid pass hole dock with measuring cell and seal when measuring zonal pressure, the oil of other layers can be up through axial passageway bridge, and do not influence the ordinary production of other layers; And the present invention is provided with in crossing the liquid main body and manages in mobilizable, should in pipe can be implemented in the resident of diverse location in the liquid main body by axial locking mechanism, thereby realize the butt joint of both flowing holes or do not dock two states, thereby make the present invention after finishing pressure measurement, can carry out the water blockoff measure.
