Abstract
The utility model relates to a tool used for fixing a casing pipe in the oil field production. The tool has the structure that a center slide block is inserted into a body, and the center slide block and a connecting rod are connected by an upper pin shaft. The connecting rod and an anchor fluke are connected by a lower pin shaft, and the anchor fluke and the body are connected by a pin shaft. A positioning ring is arranged on the upper end of the body. A pin passes through the positioning ring and is clamped in a pin groove in the center slide block. The utility model has the advantages that well depth is large; when stress situation is complex, the use of the utility model is still very safe; the utility model is very convenient and safe in use in the fixing well production.
Description
The utility model relates to the instrument that is used for fixing sleeve pipe in the oil drilling well cementation.
At present, on-the-spot used earth anchor comprises body, connecting rod and slide block etc., and there is following shortcoming in this earth anchor: because the external diameter of slide block is less than casing inner diameter, and when well depth is big, the bottom pressure height, the stressing conditions complexity is out of order easily; And its anchor fluke is not replaceable etc., therefore uses inconvenient.
The purpose of this utility model is to provide a kind of safety, and earth anchor easy to use.
The utility model is realized in the following manner: first kind of embodiment is, a kind of earth anchor, form by body 11, central slider 5, connecting rod 7 and ram's horn 9 etc., central slider 5 is inserted in the body 11, connect by upper pin between central slider 5 and the connecting rod 7, connect by lower bearing pin between connecting rod 7 and the anchor fluke 9, connect by bearing pin between anchor fluke 9 and the body 11, locating ring 2 is placed in the upper end of body 11, and pin 3 passes in the cotter slot that snaps in again behind the locating ring 2 on the central slider 5.
Another kind of embodiment is: a kind of earth anchor, form by body 11, central slider 5, central tube 12, connecting rod 7 and ram's horn 9 etc., central slider 5 is inserted in the body 11, connect by upper pin between central slider 5 and the connecting rod 7, connect by lower bearing pin between connecting rod 7 and the anchor fluke 9, connect by bearing pin between anchor fluke 9 and the body 11, the external diameter of central slider 5 is greater than the upper strata casing inner diameter, pin 3 is positioned at outside the sealing range of sealing ring 4 and sealing ring 12 on the body 11, is in the position of no seal request.
Advantage of the present utility model is owing to adopted the external diameter of the external diameter of locating ring location and central slider greater than sleeve pipe respectively, and is therefore bigger at well depth, during the stressing conditions complexity, its use is also very safe, and anchor fluke adopts replaceable mode, in well cementation is produced, easy to use, safety.
Fig. 1 is the structure chart of first kind of embodiment of the utility model;
Fig. 2 is the structure chart of second kind of embodiment of the utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail.
The earth anchor of first kind of embodiment as shown in Figure 1, by body 11, central slider 5, central tube 12, compositions such as connecting rod 7 and ram's horn 9, central slider 5 is inserted in the body 11,11 of central slider 5 and bodies pass through O shape rubber seal 4 and O shape rubber seal 12 realizes sealing, connect by upper pin 6 between central slider 5 and the connecting rod 7, connect by lower bearing pin 8 between connecting rod 7 and the anchor fluke 9, connect by bearing pin 10 between anchor fluke 9 and the body 11, locating ring 2 is placed in the upper end of body 11, pin 3 passes in the cotter slot that snaps in again behind the locating ring 2 on the central slider 5, and anchor fluke 9 is a field-replaceable unit.
The earth anchor of second kind of embodiment as shown in Figure 2, by body 11, central slider 5, central tube 12, compositions such as connecting rod 7 and ram's horn 9, central slider 5 is inserted in the body 11,11 of central slider 5 and bodies pass through O shape rubber seal 4 and O shape rubber seal 12 realizes sealing, connect by upper pin 6 between central slider 5 and the connecting rod 7, connect by lower bearing pin 8 between connecting rod 7 and the anchor fluke 9, connect by bearing pin 10 between anchor fluke 9 and the body 11, the external diameter of central slider 5 is greater than the internal diameter of upper strata sleeve pipe 13, pin 3 is positioned at outside the sealing range of O shape rubber seal 4 and O shape rubber seal 12 on the body 11, is in the position of no seal request.
The operating principle of this earth anchor is as follows, kit is connected in the bottom of production string string by casing coupling 1, when cementing operation finishes, cementing plug comes downwards to the earth anchor place and is pressed on the central slider 5, when this pressure reached to certain value, pin 3 was cut off, and central slider 5 is with can be descending, because 6,8,10 these three bearing pin distributions triangular in shape, and stub axle 10 is fixed on the body 11, so when bearing pin 6 is descending with central slider 5, just outwards upset under the effect of connecting rod 7 of anchor fluke 9, continue the moulding plug, embed the stratum until the tip of anchor fluke 9, carry whole bunch tube on again, at this moment, because anchor fluke 9 is the wedging stratum, the actual lower end that is equivalent to bunch tube is fixed, on carry sleeve pipe, force sleeve pipe elongation, carry to builder's tonnage, promptly reach sleeve pipe is applied prestressed effect.
