Abstract
The utility model relates to an expansion packer, comprising a rubber ring, a tube core shaft and press rings. The tube core shaft is sleeved by the rubber ring which is in an interference fit with the tube core shaft. The press ring is provided with an axial inclined plane and is positioned at two ends of the tube core shaft and the rubber ring in pairs. The two ends of the rubber ring and the tube core shaft are coated by the press ring sealing. One of the press rings is provided with a vent hole. Air is injected in the rubber ring to reach the function of expansion packing. The packer enters a horizontal well along with a pipeline assembly, and the air is injected in the packer through an injecting pipeline. The rubber ring of the packer expands, which makes the rubber ring tightly contact with the hole wall and separates the underground pipeline from the ring-shaped gap of an open well. In this case, a multi-section grouting and well cementation and other work can be conducted.
Description
Technical field
The utility model relates to a kind of packing instrument that a kind of annular gap that is used for interior pipeline of directed horizontal well and bore hole carries out packing, pipeline and bore hole annular gap are carried out packing can carry out segmentation well cementation or other special operation, particularly a kind of soil environment is administered the packer of directed horizontal well completion operation.
Background technology
At present, external a lot of soil environments are administered and are all adopted peupendicular hole soil to be carried out modes such as exhaust or gas injection, carry out soil environment and administer, and domestic soil environment is administered at the early-stage.Yet, administer the directed horizontal wells that adopt for the large area region soil environment more, adopt horizontal well to mainly contain following advantage: to adopt horizontal well for the pollution in wide area zone, can reduce integrated cost; Adopt horizontal well to help controlling the further diffusion of pollution more; Have on the face of land under the situation in obstruction (for example building, river), can only adopt horizontal well to carry out soil environment and administer.When soil environment administer to adopt directed level, but, when implementing completion practice, need different pipe sections is carried out different operations, thereby need the annular gap between packing horizontal well gut line and bore hole, need to adopt the packer of different packing modes according to different bottoms.So, design a kind of swell packers that is usually used in layer of sand soil, satisfy the packing mode of horizontal well, can also be used for the particular section packing operation of directed horizontal well, be the technical barrier that the industry needs to be resolved hurrily.
The utility model content
In view of this, the purpose of this utility model be to provide a kind of can the directed horizontal well gut line of packing and the packer of bore hole annular gap, satisfy the completion practice requirement of directed horizontal well.
For achieving the above object, originally be that the technical scheme that utility model adopts is: a kind of swell packers, it comprises rubber ring, die axle and pressure ring, this die outer shaft sleeve is provided with rubber ring and mutual interference fit, this pressure ring is provided with axial slope and locatees the two ends that are arranged on die axle and rubber ring in pairs, and described pressure ring sealed packet is overlying on described rubber ring and die axle two ends; Offer air vent on the described pressure ring therein.
The axial slope angle of inclination of described pressure ring is not more than 5 °.
Described sealing coating scribbles fluid sealant for the junction.
Description of drawings
Fig. 1 is the packing sectional view of the utility model swell packers.
The specific embodiment
Be described below in conjunction with the specific embodiment of accompanying drawing the utility model swell packers.
As shown in Figure 1, swell packers of the present utility model, it includes rubber ring 1, die axle 2 and pressure ring 3, these die axle 2 outer rubber ring 1 and mutual interference fit of being arranged with, this pressure ring 3 is provided with axial slope and locatees the two ends that are arranged on die axle 2 and rubber ring 1 in pairs, and described pressure ring 3 sealed packets are overlying on described rubber ring 1 and die axle 2 two ends; Offer air vent 4 on the pressure ring 3 therein.Rubber ring 1 adopts expansion character greater than 400% rubber parts, this pressure ring 3 is provided with an inclined-plane and rubber ring 1 and die axle 2 and is tightly connected, the angle of inclination of this axial slope is not more than 5 °, because rubber ring 1 has better elastic, so this inclination angle of inclined plane promptly can guarantee to install, can also make each other closely to connect.Be tightly connected to scribbling fluid sealant in the junction.Offer air vent on a pressure ring 3 therein, in rubber ring 1, inject air, reach the effect of expansion packing.After being lowered to horizontal well, the air vent of swell packers is inflated operation by gas tube, be charged to setting pressure after, stop to inflate operation, and keep this pressure, promptly finish packing pipeline and bore hole annular gap, can carry out other operation, treat that predetermined operation is finished after, can exit.
Adopt the utility model expansion of structure packer, can be the completion of the directed horizontal well of soil and conventional pipe laying slip casting operation etc.And, according to the degree of depth in hole, can regulate the blowing pressure, satisfy the packing requirement of different depth horizontal well.
