Detailed Description
As shown in fig. 1 to 3, fig. 1 to 3 show a structure of a supporting device 1 for receiving an inclinometer in this embodiment. The supporting device 1 includes a base 11, a supporting bracket 12 and an elastic member 13. The support bracket 12 and the elastic member 13 are disposed in the housing 11. The support bracket 12 is connected with the base body 11 in a sliding way, and the elastic piece 13 elastically supports the support bracket 12.
As shown in fig. 4 and 5, the holder body 11 includes a cylinder 111, a mounting seat 112 and a connecting member 113. The cylinder 111 is a straight cylinder. The cross-section of the cylinder 111 is circular. Barrel 111 includes a top end 114 and a bottom end 115 opposite top end 114. The mount 112 and the connector 113 are both disposed within the barrel 111. The mount 112 may be cylindrical coaxial with the barrel 111. The mount 112 is disposed at the bottom end 115 of the barrel 111. Opposite sides of the connecting member 113 are connected to a side wall of the mounting seat 112 and an inner wall of the cylinder 111, respectively. A connector 113 secures the mounting block 112 to a bottom end 115 of the barrel 111. The connecting member 113 may be provided in plural, and the plural connecting members 113 are uniformly distributed around the mounting seat 112. As shown in fig. 2, the mounting base 112 is provided with a mounting hole 110. The mounting holes 110 are through holes. The mounting hole 110 is provided coaxially with the cylinder 111.
As shown in fig. 2 and 3, the support bracket 12 includes a slide bar 121 and a receiving portion 122. The slide rod 121 is a straight rod, and the slide rod 121 is inserted into the mounting hole 110 of the mounting base 112. The cross-section of the slide bar 121 may be circular. The slide rod 121 is coaxial with the cylinder 111. The mounting hole 110 is in clearance fit with the slide rod 121, and the slide rod 121 can slide along the mounting hole 110. The receiving portion 122 is formed at an end of the slide rod 121 adjacent to the barrel tip 114. The receiving portion 122 is used for receiving a downward end of the inclinometer.
The elastic member 13 can be elastically deformed. The elastic member 13 is disposed between the mounting seat 112 and the receiving portion 122. Opposite ends of the elastic member 13 abut against the receiving portion 122 and the mounting seat 112, respectively. The elastic member 13 elastically supports the receiving portion 122.
When using this supporting device 1, the base body 11 of the supporting device 1 is fixed in advance in the drill rod so that the receiving portion 122 faces upward, and the rod-shaped inclinometer is thrown into the drill rod from the upper end opening of the drill rod, and the inclinometer freely falls along the drill rod. When this inclinometer striking supporting device 1's support portion 122 when supporting bracket 12 whole moves down, the elastic component 13 receives the compression and absorbs the energy that the inclinometer struck at this in-process for the process that the inclinometer struck support portion 122 obtains buffering, consequently, inclinometer and supporting device 1 are difficult to damage at collision in-process.
In an exemplary embodiment, the elastic element 13 is configured in the form of a sleeve or a spiral. The elastic member 13 is fitted around the slide rod 121. The elastic member 13 extends along the slide rod 121. The elastic member 13 may be, for example, a coil spring, a bellows, or a rubber tube.
Thus, the elastic element 13 is firmly mounted on the slide rod 121 and is not easy to fall off, and particularly, the slide rod 121 restrains the elastic element 13 from being bent during the compression of the elastic element 13, so that the elastic element 13 is compressed in the axial direction all the time.
In an exemplary embodiment, as shown in FIG. 2, the slide rod 121 extends through the mounting hole 110 of the mounting base 112, and two ends of the slide rod 121 respectively extend from two ends of the mounting base 112. The support bracket 12 further comprises a stop projection 125, the stop projection 125 being provided at the end of the slide bar 121 facing away from the receiving portion 122 and projecting radially outwardly therefrom. The stopper protrusion 125 may be circular ring-shaped. The diameter of the position-limiting protrusion 125 is larger than the diameter of the slide rod 121 and also larger than the diameter of the mounting hole 110. The stopper protrusion 125 cannot pass through the mounting hole 110.
When the rod 121 of the support bracket 12 moves upward to a certain extent, the limit projection 125 abuts against the end surface of the mounting seat 112, and since the limit projection 125 cannot pass through the mounting hole 110, the limit projection 125 limits the upward movement of the rod 121, thereby preventing the rod 121 from coming out of the mounting hole 110.
In an exemplary embodiment, the end surface of the top end 114 of the barrel 111 is an inwardly sloped first ramp 116. The first ramp 116 may be an internal conical surface coaxial with the barrel 11.
After the lower end of the inclinometer is in contact with the first inclined plane 116, the first inclined plane 116 can guide the inclinometer to enter the cylinder 111, and the inclinometer can be more centered after entering the cylinder 111 and being inserted into the cylinder 111, so that the deviation error of the inclinometer during measurement can be reduced, and the measured data can reflect the track data of the well more truly.
In an exemplary embodiment, as shown in fig. 2, 3 and 6, the docking portion 122 includes a base 123 and a plurality of cradling claws 124. The base 123 may be disc-shaped. The base 123 is disposed at one end of the slide rod 121. The base 123 and the slide rod 121 may be connected by a screw thread or by welding. A plurality of prongs 124 extend from the base 123. A plurality of prongs 124 are evenly distributed around the base 123. The holding claw 124 extends towards the inner edge of the top end 114 of the cylinder 111, and the surface of the holding claw 124 facing away from the mounting seat 112 is a second inclined surface 126. The distance between the second ramp 126 to the axis of the barrel 111 tapers in a direction approaching the bottom end 115 of the barrel 111. The second ramp 126 may be an inner tapered surface disposed coaxially with the barrel 111.
The lower end of the inclinometer enters the cylinder body 111 and then contacts with the second inclined plane 126 of the supporting claw 124, the second inclined plane 126 can guide the lower end of the inclinometer to approach to the middle of the supporting part 122 and finally abut against the base 123 located at the center, and the inclinometer is more centered, so that the deflection error of the inclinometer during measurement can be further reduced, and the measured data can reflect the track data of the well hole more truly.
In an exemplary embodiment, referring to FIG. 1, when the support bracket 12 is unstressed, the first ramp 116 of the barrel 111 is aligned with the second ramp 126 of the pawl 124.
When the support bracket 12 is not stressed, the elastic member 13 only bears the weight of the support bracket 12, and the first inclined surface 116 and the second inclined surface 126 of the cylinder 111 are aligned with each other. During the projection, if the inclinometer is firstly abutted against the first inclined plane 116, the inclinometer can smoothly slide into the second inclined plane 126 along the first inclined plane 116, and the inclinometer can smoothly slide into the middle of the supporting part 122.
In an exemplary embodiment, as shown in fig. 5, the diameter of the mount 112 is smaller than the inner diameter of the cylinder 111, and a gap between the mount 112 and the cylinder 111 forms the first fluid passage 14. As shown in fig. 6, the gap between two adjacent prongs 124 forms a second fluid passage 15. The first fluid passage 14 and the second fluid passage 15 are communicated with each other.
The drilling fluid can flow into the cylinder 111 from the second fluid passage 15 between two adjacent supporting claws 124 and then flow out from the first fluid passage 14 between the mounting seat 112 and the cylinder 111. Therefore, the supporting device 1 and the inclinometer cannot block the flow of the drilling fluid in the drill rod to influence the normal circulation of the drilling fluid.
