Abstract
The invention discloses a plugging tool used in the exploitation and test process of petroleum, natural gas, salt brine, terrestrial heat and the like, and specifically relates to a multi-stage packing bridge plug which comprises a first connecting sleeve (1), a second connecting sleeve (4), a release ring (5), a mandrel (6) and a base (7), wherein the first connecting sleeve (1), the second connecting sleeve (4), the release ring (5) are all sleeved on the mandrel (6); the second connecting sleeve (4) is connected on the release ring (5); and the mandrel (6) is further sleeved with a first rubber cylinder (2) and a second rubber cylinder (3). The multi-stage packing bridge plug disclosed by the invention is simple in structure, convenient to use and easy to manufacture, and has long service life.
Description
Technical field
The present invention relates to a kind of oil, natural gas, bittern, underground heat etc. exploited capping tools used in the test process, particularly relate to a kind of multistage packing bridging plug.
Background technology
At present, in that oil, natural gas, bittern, underground heat etc. are exploited in the test process, when multilayer is successively tested; When needing layer position that shutoff do not test; The general bridging plug that adopts carries out packing, and along with the degree of depth of oil gas well development is more and more darker, the bridging plug resistance to compression rank that adopted in the past is low; Bearing capacity and heatproof design all can not be satisfied the needs of deep well high pressure operation, influence operating efficiency greatly.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly exploits capping tools used in the test process--multistage packing bridging plug to oil, natural gas, bittern, underground heat etc.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: multistage packing bridging plug; Comprise adapter sleeve one, adapter sleeve two, the ring of giving up, axle and base; Adapter sleeve one, adapter sleeve two and the ring of giving up all are sleeved on the axle, are connected with adapter sleeve two on the ring of giving up, and on said axle, also are set with packing element one and packing element two.The design of packing element one and packing element two can be strengthened buffering, and can dilatancy, well shutoff aspect under the effect of stress.
Be provided with between adapter sleeve one, the adapter sleeve two at said packing element one and packing element two.This structure can better guarantee under the extruding force effect of adapter sleeve one, two pairs of packing elements one of adapter sleeve and packing element two, makes packing element one and the shutoff of two pairs of aspects of packing element after the expansion.
Be provided with screw thread 20～50mm on one's body in adapter sleeve one, two weeks of adapter sleeve.
Different at said packing element one with the material of packing element two.Packing element 1 is oil resistant, alkaline-resisting, acidproof, resistant to elevated temperatures rubber with packing element 23, the sealing performance during with the assurance packing.
The bearing capacity of the multistage packing bridging plug of the present invention reaches 105Mpa, and heatproof reaches 200 ℃, can satisfy the needs of present deep well high pressure packing.Multistage packing bridging plug has that compact conformation, external diameter are little, cable sets, and is easy to bore the sleeve pipe that removes, is applicable to plurality of specifications; The monolithic slips is avoided setting midway and is prone to bore and removes; The give up packing element and the ratchet lock ring of ring, multistage different hardness of unsteady metal formed reliable sealing system between sleeve pipe and seal; Multistage packing bridging plug can be realized comprehensive optimization of properties of product, to substitute the bridging plug of buying from joint venture always; Continue innovation on this basis, and realize the large-scale production of new product and apply purpose.
In sum, the multistage packing bridging plug of the present invention is rational in infrastructure, practical, and physical life is long.
