Description
Technical field
The utility model relates to a twin-well vocal imitation skill field, realizes specifically the device that two protective casings are installed in a kind of conduit.
Background technology
In reality, a twin-well technique is routinely cannot in pit shaft, realize two protective casings are installed, main cause is because pit shaft inside dimension is more limited, during mounting technique sleeve pipe, will make two sleeve pipes draw close just and can not interfere shaft in wall to center, after Dan Xiang draws close at center, can cause again two, the upper strata fan-shaped flange of four-way junction of casing mutually to interfere, also not have at present a kind of technique to realize two protective casings are installed in conduit.
Therefore, for overcoming the deficiency of above-mentioned technology, design a kind of device that two sleeve pipes are installed, just inventor's problem to be solved of realizing in conduit.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide the device of realizing two protective casings of installation in a kind of conduit, the restriction that protective casing is not installed because of pipe inner wall and upper strata four-way junction of casing, can be arranged on smoothly in conduit, save well head space, equipment investment cost is low, and oil and gas production improves obviously, has very high practical value.
The utility model solves the technical scheme that its technical problem adopts: in a kind of conduit, realize the device that two protective casings are installed, it is characterized in that: device comprises two casing head of well heads, casing hanger, protective casing, conduit, the slips that falls, two casing head of well heads bottom is provided with down slips, the slips that falls blocks conduit, sealing ring sealing duct, two casing head of well heads are inner with casing hanger Suspension Technique sleeve pipe, sealing device Sealed casing pipe hanger, casing hanger bottom belt length imports groove.
Further, described conduit, sealing ring, the slips that falls are of a size of 26 inches, and protective casing, casing hanger are of a size of 95/8 inch.
Further, described casing hanger bottom is directly connected with protective casing upper end, and the casing hanger top lifting tool that is threaded hangs the connected protective casing of more piece below casing hanger.
The beneficial effects of the utility model are:
1, the utility model is saved well head space greatly, at the pit shaft that originally can only bung down, twin-well mouth is installed, and equipment investment cost is low, and oil and gas production improves significantly.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model process principle figure.
Fig. 3 is that the utility model structure connects upper strata four-way junction of casing schematic diagram.
Description of reference numerals: 1-casing hanger; The two casing head of well heads of 2-; 3-conduit; 4-protective casing; 5-falls slips; 6-sealing device; 7-sealing ring; 8-upper strata four-way junction of casing assembly; A-casing hanger lower surface and sleeve pipe external diameter intersection point; B-casing coupling starting point; C-casing coupling starting point is to box cupling external diameter horizontal-extending intersection point.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 realizes the apparatus structure schematic diagram that two protective casings are installed in a kind of conduit of the utility model, device comprises two casing head of well heads 2, the casing hanger 1 of 95/8 inch, the protective casing 4 of 95/8 inch, the conduit 3 of 26 inches, the slips 5 of 26 inches, two casing head of well heads 2 bottoms are provided with the slips 5 of 26 inches, 26 inches are fallen slips 5 and block the conduit 3 of 26 inches, the sealing ring 7 of 26 inches seals the conduit 3 of 26 inches, the inner casing hanger 1 with 95/8 inch of two casing head of well heads 2 hangs the protective casing 4 of 95/8 inch, the sealing device 6 of 95/8 inch seals the casing hanger 1 of 95/8 inch.
Fig. 2 is the utility model process principle figure, and it is in definite value situation that the utility model utilizes A point and B point distance, make that A point and B point try one's best away from, the angle between AB line segment and AC line segment will be very little, when just negligible as far as to a certain degree time.
Fig. 3 is that the utility model structure connects upper strata four-way junction of casing schematic diagram, after casing hanger 1 installation of 95/8 inch, screw thread place is lifted by crane in top and slice off, and polishes smooth, and upper strata four-way junction of casing assembly 8 is installed.
In the utility model field-mounted process, the casing hanger 1 of 95/8 inch is directly connected with the protective casing 4 of 95/8 inch, rather than be indirectly connected by conventional double male joint and female box cupling, casing hanger 1 top of the 95/8 inch lifting tool that is threaded, hang the protective casing 4 of 95/8 inch that more piece is connected below, the total Beijing South Maxpower Technology Co. Ltd of sleeve pipe reaches 350 tons, during setting of casing due to Action of Gravity Field, it is flexible that the protective casing 4 of 95/8 inch can become, thereby the box cupling that makes the protective casing 4 of 95/8 inch can be close to 26 inches conduit 3 inwalls and in lower going-into-well, when being lowered into the casing hanger 1 of 95/8 inch, because the casing hanger of 95/8 inch 1 bottom imports groove from belt length, the casing hanger of 95/8 inch 1 can be imported to two casing head of well head 2 inner chambers, enough far away of the distance of ordering due to Action of Gravity Field and A point and B, the casing hanger 1 that can make script depart from 95/8 inch is centered in two casing head of well head 2 inner chambers by force, thereby two 95/8 inch of protective casings 4 of the interior installation of the conduit 3 of realizing 26 inches, the utility model is saved well head space greatly, at the pit shaft that originally can only bung down, twin-well mouth is installed, equipment investment cost is low, oil and gas production improves significantly.
