Abstract
The utility model provides an integrated process device for sand removal and fishing outside a pipe. The device comprises an oil string or a drill string, a releasing connection sand removal pipe spear, a sand removal pipe, a sand removal pipe rubber seal, an upper rubber seal, a sieve tube, a lower rubber seal and a pressure limiting check valve, wherein, the upper end of the releasing connection sand removal pipe spear is connected with the oil string or drill string while the lower end thereof is connected with a sand removal pipe string; the sand removal pipe, the sand removal pipe rubber seal, the upper rubber seal, the sieve tube, the lower rubber seal and the pressure limiting check valve are connected in sequence below the releasing connection sand removal pipe spear in the sand removal pipe string; and the oil string or drill string, the releasing connection sand removal pipe spear and the sand removal pipe string are installed in a bushing. The utility model has the characteristics of reasonable structure, convenient operation, continuously repeated sand removal and fishing, and the capability that one pipe string accomplishes multiple construction tasks, and is mainly applied in the oil recovery process involved in oil production.
Description
One, technical field:
The utility model relates to the tubing string and the kit of oil exploitation well, and the integral process device is salvaged in the outer sand washing of particularly a kind of pipe.
Two, background technology:
Tradition is salvaged the filter sand tubing string in selective sand control, the stratified injection water technology, the general method that adopts working rig to force and promote, though also can salvage sometimes, but there are following shortcoming or deficiency: 1. because the sand screen outer wall is crowded with back-up sand or reservoir sand, increased the upper lifting force of salvaging sand screen and layer separating packer greatly, traditional implement is difficult to reach the requirement of lifting force; Just need when 2. can not promoting to go up overhaul facilities, cause duty cycle long, cost is high.
Three, summary of the invention:
The purpose of this utility model provides the outer sand washing of a kind of improved pipe and salvages the integral process device, adopt reversible to draw to connect sand clean out pipe to drag for lance, sand clean out pipe, sand clean out pipe rubber envelope, go up the rubber envelope, screen casing, the co-ordinative construction of rubber envelope, pressure limiting ball-and-seat down, the shortcoming or the deficiency that had both effectively overcome or avoided existing in the above-mentioned prior art can improve fishing success ratio and operating efficiency again.
The integral process device is salvaged in the outer sand washing of pipe described in the utility model, comprise tubing string or drill string, reversible draw connect that sand clean out pipe drags for lance, sand clean out pipe, sand clean out pipe rubber envelope, goes up the rubber envelope, screen casing, rubber envelope, pressure limiting ball-and-seat down.Described reversible draws and connects sand clean out pipe and drag for lance upper end and be connected with tubing string or drill string, the lower end is connected with the filter sand tubing string, reversible in the filter sand tubing string draws and connects that sand clean out pipe drags under the lance in turn with sand clean out pipe, sand clean out pipe rubber envelope, goes up rubber envelope, screen casing, rubber envelope, pressure limiting ball-and-seat are connected down, and tubing string or drill string, reversible draw and connect that sand clean out pipe drags for lance and the filter sand tubing string is installed in the sleeve pipe.
Wherein, described reversible draws and connects sand clean out pipe and drag for lance and comprise top connection and coupled mandrel and sand clean out pipe, and locking nut and slips are installed on the mandrel in turn.Described slips is fixed on the mandrel by guider screw.Described rubber envelope and the relative respectively upper and lower side that is installed on screen casing of following rubber envelope gone up.
The utility model has following advantage compared with prior art:
1, have simultaneously sand washing and pull out the filter two functions, can salvage immediately after the sand washing;
2, sand washing and pull out two processes of filter and can carry out repeatedly improves operating efficiency;
3, the routine work tractor hoist can realize pulling out the filter construction;
4, avoid damaging sleeve pipe, shorten the engineering time, improve productivity effect, reduce cost.
Four, description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 connects the structural representation that sand clean out pipe drags for lance for drawing by reversible shown in Figure 1.
Five, the specific embodiment:
Consult Fig. 1 and Fig. 2, the integral process device is salvaged in the outer sand washing of a kind of pipe, comprise tubing string or drill string, reversible draw connect that sand clean out pipe drags for lance, sand clean out pipe, sand clean out pipe rubber envelope, goes up the rubber envelope, screen casing, rubber envelope, pressure limiting ball-and-seat down.Reversible draws and connects sand clean out pipe and drag for lance 2 upper ends and be connected with tubing string or drill string 1, the lower end is connected with filter sand tubing string 8, reversible in the filter sand tubing string 8 draw connect sand clean out pipe drag for lance 2 times in turn with sand clean out pipe 10, sand clean out pipe rubber envelope 3, go up rubber envelope 4, screen casing 5, rubber envelope 6, pressure limiting ball-and-seat 7 are connected down, tubing string or drill string 1, reversible draw and connect that sand clean out pipe drags for lance 2 and filter sand tubing string 8 is installed in the sleeve pipe 9.
Reversible draws and connects sand clean out pipe and drag for lance 2 and comprise top connection 21 and coupled mandrel 25 and sand clean out pipe 26, and locking nut 22 and slips 24 are installed on the mandrel 25 in turn.Slips 24 is fixed on the mandrel 25 by guider screw 23.Last rubber envelope 4 and the following rubber envelope 6 relative respectively upper and lower sides that are installed on screen casing 5.
During operation, every sand clean out pipe box cupling of the utility model place connects a sand clean out pipe rubber envelope 3, sand clean out pipe 10 bottoms connect goes up rubber envelope 4, screen casing 5, following rubber envelope 6, pressure limiting ball-and-seat 7 (pressure limiting 15Mpa), it is lowered in the filter sand tubing string 8, pump into sand cleaning fluid, sand cleaning fluid flows into filter sand tubing string and casing annulus from screen casing 5 under the restriction of last rubber envelope 4, screen casing 5 and following rubber envelope 6, realize the direct circulation sand washing.The main effect of the sand clean out pipe rubber at every sand clean out pipe box cupling place envelope 3 is to prevent that sand cleaning fluid from scurrying in the sand clean out pipe again from top filter sand tubing string.Transfer tubing string gradually, can progressively wash filter sand tubing string apposition sand from top to down, up to the tail pipe that pours the sand screen bottom.After pouring tail pipe, reversible draws and connects sand clean out pipe and drag for lance 2 and combine with filter sand tubing string 8, on carry and can realize salvaging.As above carry and meet card and pull out when motionless, withdraw from reversible and draw and connect sand clean out pipe and drag for lance 2 and carry out sand washing again and salvage, till extracting filter sand tubing string 8.
