Abstract
The utility model relates to an oil filed well pipeline reinforcing and supporting device, which resolves the problems of the prior art that the oil field pipeline is extruded or deformed by various extra-high pressure external extrusion forces. The external part of the oil field pipeline is sleeved by a plurality of outer sleeve pipes. Two ends of each outer sleeve pipe are respectively connected to the oil filed pipeline through a cementing valve body. A set cement layer is disposed in a ring-shaped space formed by the oil field pipeline and the outer sleeve pipe. The oil filed well pipeline reinforcing and supporting device can resist the strong external extrusion force of a stratum to some extent, and can reduce cost of reinforcing an oil field.
Description
Technical field
The utility model relates to the field, oil field, especially relates to a kind of oil well pipe strengthening bracing or strutting arrangement.
Background technology
At oil field well; pipeline often can run into super-pressure and squeeze the stratum outward; such as salt rock stratum, shale layer etc.; because these bottoms are wriggled easily; cause out husky extruding to wait to produce various super-pressure and squeeze power outward, often can cause that oil field pipe is squeezed to be ruined or be out of shape, had a strong impact on the production of Oil/gas Well; increase workover cost, more can cause oil well to scrap when serious.
Summary of the invention
The utility model technical issues that need to address are: in order to overcome the problem of above-mentioned middle existence, provide a kind of power of squeezing, cost-effective oil field pipe reinforced support device again can resisted to a certain extent outside the stratum.
The technical scheme that its technical problem that solves the utility model adopts is: described oil well pipe strengthening bracing or strutting arrangement has comprised several cementing valve bodies and several outer tubes, described outer tube is sleeved on the outside of oil field pipe, the two ends of each outer tube are connected with oil field pipe by the cementing valve body respectively, are provided with the Behavior of Hardened Cement Paste layer in the annular space that described oil field pipe and outer tube form.
More specifically, the quantity of described outer tube is 1-20, specifically can determine according to the geographical situation of the length of oil field pipe and region, place the quantity of required outer tube.
Further, described cementing valve body is to adopt thread connecting mode to be connected with oil field pipe with outer tube, and this kind connected mode convenient disassembly is convenient to install and maintenance.
The beneficial effects of the utility model are: squeeze outside the super-pressure in oil well in the geographical situation on stratum; be provided with the double combination casing protection; and the centre has additional the Behavior of Hardened Cement Paste layer; reached and to have resisted to a certain extent the requirement of squeezing power outside the stratum; reduced the cost of reinforcing oil well; oil well is simplified the structure, and save drilling cost, the cementing operation process is also simple.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the overall structure schematic diagram of a kind of oil well pipe strengthening bracing or strutting arrangement described in the utility model.
Accompanying drawing acceptance of the bid score state as follows: 1, cementing valve body, 2, outer tube, 3, oil field pipe, 4, the Behavior of Hardened Cement Paste layer.
The specific embodiment
1 pair of the utility model is described in further detail by reference to the accompanying drawings now.This accompanying drawing is the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
Oil well pipe strengthening bracing or strutting arrangement comprises several cementing valve body 1 and several outer tubes 2 as shown in Figure 1, the outer cover of described oil field pipe 3 is equipped with several outer tubes 2, the two ends of each outer tube 2 are connected with oil field pipe 3 by cementing valve body 1 respectively, are provided with Behavior of Hardened Cement Paste layer 4 in the annular space that oil field pipe 3 and outer tube 2 form.The design of two-layer equation sleeve pipe can be resisted to a certain extent and be squeezed power outside the stratum, can reduce again the cost of reinforcing oil well, and oil well is simplified the structure, and saves drilling cost, and the cementing operation process is also simple.
According to the geogen of region, pipeline place and the length of oil field pipe, the quantity of described outer tube 2 can adopt 1-20.
Cementing valve body 1 is to adopt thread connecting mode and outer tube 2 to be connected with oil field pipe to be connected.This connected mode convenient disassembly is convenient to install and maintenance.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the manual, must determine its technical scope according to the claim scope.
