Description
Technical field
It is a kind of oil pipe reduced pipe connection frame and operating device the utility model relates to drilling tool technical field.
Background technique
In recent years, it is gradually widely applied by the oil field well construction operation of Core equipment of coiled tubing, range relates to
And the multiple fields such as drilling well, complete well, formation testing, oil recovery, well workover.Under normal conditions, it is generally used whole coiled tubing and carries out oil
Field engineer operation, but this scheme will try to find some other ways with regard to infeasible in some special cases.For example, oil well ultra-deep is (such as
7000 meters or more), if necessarily leading to the roller superelevation, the ultra-wide that store oil pipe, no still according to the thinking for using whole coiled tubing
Meet the requirement of highway transport statute, or working well can not be transported at all；For another example, when the latus rectum of downhole tool is smaller
When, allow by oil pipe outer diameter also accordingly become smaller (such as below 1.75 inch), if using the whole oil pipe compared with small diameter tube,
Mechanical property or the requirement for not being able to satisfy operation technique in other respects.Single coiled tubing is size-constrained, mechanical performance
Demand is unable to meet production,
Coiled tubing is usually wound on vehicle-mounted working drum and is stored and transported.Loaded bassinet structure size and space
Limitation, and for keeping oil pipe performance, guarantee traffic safety, meet the considerations of various aspects such as job requirements, the main body of roller
The diameter of part --- tube filler can neither too small (greater than, equal to 40 times coiled tubing outer diameters), can not be too big.Although continuous oil
The rigidity of pipe, toughness and Anti-pull-press comprehensive mechanical performance are very outstanding, and the ability of resistance to deformation is also very strong, but passes through roller
It is still inevitably plastically deformed after winding, is in bending state when expansion.Therefore, often there is such situation: making
When industry, although its bending deformation reduces after coiled tubing passes through the clamping of injector, correction, it can be once detached from injector,
It is still curved under free state, therefore, the free segment axis of two sections of reducing coiled tubings as connecting object can not be right
In.And the connector as core component, the well control due to that must pass through blowout prevention box and its underpart during the well entry process fill
It sets, so that its outer diameter is limited by chamber size in blowout prevention box and well control device.Therefore, connector maximum outside diameter is usually and coiled tubing
Middle Large Diameter Pipeline person is identical, and self structure must be exquisite, small and exquisite, but brings radial dimension amount of redundancy is few, rigidity is big etc. again therewith
Problem, causes its applicable narrow space, and fault-tolerant ability is poor.So connector is to the continuous pipe free segment of the reducing to be connected
Axial alignment degree requires very high.The coiled tubing that deformation occurs in use, leads to the freedom of two sections of reducing coiled tubings
Section cannot achieve centering, and correction difficulty is big, and before, the work of such connection reducing oil pipe is all in the shape without any auxiliary equipment
Under condition, the correcting deformed coiled tubing of the simple and crude tool such as manpower pipe wrench, crowbar is fully relied on, makes the two axis pair as far as possible
In, so as to connector by the free segment lock ring of reducing coiled tubing together.It is arduously also dangerous that this is time consuming.
