Description
Technical field
The utility model is related to a kind of well cementation auxiliary equipment for reducing cementing concrete porosity, belongs to petroleum machinery equipment.
Background technology
In Process of Oil Well Drilling, Service Life of Casing may be caused to shorten, occur safe thing because cementing quality is bad
Therefore wait harm.Wherein, it is easy if cementing concrete and sleeve pipe weak bonding particularly in the gas reservoir development of high pressure acid gas-containing
Generation gases at high pressure crush toxic and harmful gas invaded formation in sleeve pipe leakage, gas reservoir and pollute or even go out ground with crack channelling
Table causes great casualties.Therefore develop one kind to be intended to improve cementing concrete bonding quality, cementing concrete hole can be reduced
The well cementation auxiliary equipment of rate is extremely necessary.Cementing quality can be improved using the equipment, it is ensured that sleeve pipe working strength and service life
Efficiently produce and lay the foundation for oil security.
The content of the invention
The purpose of this utility model is:It is cementing to ensure cementing quality to improve cementing concrete and sleeve pipe in drilling process
There is provided a kind of well cementation auxiliary equipment for reducing cementing concrete porosity for the safety progress produced with subsequent development.
In order to achieve the above object, the utility model uses following technical scheme:A kind of reduction cementing concrete porosity
Cement the well auxiliary equipment, including frequency converter, around thread casing, plug, magnetic ellipsoid, cementing concrete, after pad, ampere wires;It is special
Levy and be:Ampere wires are wound in coiling sleeve outer wall, ampere wires are divided to two strands to come and go winding and be connected with the frequency converter on ground;
Plug is located at coiling sleeve bottom, for separating cementing concrete and after pad;Magnetic ellipsoid is dispersed in cementing concrete, with well cementation
The outer annular space that cement enters between thread casing and stratum.
The utility model has the advantages that:(1)Promote the cementing of cementing concrete and sleeve pipe, it is ensured that cementing quality,
Ensure that oil security is efficiently produced;(2)It can be used using extensive most of oilwell drillings, with suitable practicality and wide
Market;(3)Equipment is simple, is easily installed and promotes;(4)Cost is low, pollutes small.
Brief description of the drawings
Fig. 1 is overall construction drawing of the present utility model.
Fig. 2 is coiling sleeve structure figure of the present utility model.
Embodiment
As shown in figure 1, in order to achieve the above object, the utility model uses following technical scheme:One kind reduces well cementation water
The well cementation auxiliary equipment of mud porosity, device includes frequency converter 1, coiling set 2, plug 3, magnetic ellipsoid 4, cementing concrete 5, rearmounted
Liquid 6, ampere wires 7;It is characterized in that:Ampere wires 7 are being wound around the outer wall of thread casing 2, two strands of ampere wires 7 point come and go winding
And be connected with the frequency converter 1 on ground;Plug 3 is located at around the bottom of thread casing 2, for separating cementing concrete 5 and after pad 6;Magnetic
Ellipsoid 4 is dispersed in cementing concrete 5, the outer annular space entered with cementing concrete 5 between thread casing 2 and stratum.
As shown in Fig. 2 device is included around thread casing 2, ampere wires 7;It is characterized in that:Ampere wires 7 are wound in coiling
On the outer wall of sleeve pipe 2, the stage casing of ampere wires 7 is located at around the bottom of thread casing 2, by way of two strands wind, and makes the external change of two joints
The formation current loop of frequency device 1.
As shown in Figure 1 and Figure 2, the utility model patent realizes that the method for reducing cementing concrete porosity is:Around thread casing
The ampere wires 7 of external frequency converter 1 are wound on 2, it is incidentally upper strong around thread casing 2 by making to the input current of ampere wires 7
Magnetic field;Magnetic ellipsoid 4, which is mixed into cementing concrete 5, to be injected in thread casing 2, then is driven by the separation of plug 3 and after pad 6, Gu
The toric space that well cement 5 enters between thread casing 2 and stratum;When plug 3 is reached around 2 bottom of thread casing, to electricity
The input current of conductance line 7, forms the high-intensity magnetic field of change, and magnetic ellipsoid 4 vibrates in the high-intensity magnetic field of formation with changes of magnetic field;It is logical
Stratum and the annular gap between thread casing 2 can be fully populated with by crossing the vibration cementing cement 5 of magnetic ellipsoid 4 so that well cementation water
Mud 5 can be preferably with stratum and cementing around thread casing 2, realizes the effect for reducing cementing concrete porosity.
The utility model has simple in construction, and cost is relatively low, it is contemplated that the advantages of working well.It can reduce to a certain extent
Cementing concrete porosity improves cementing quality, to ensure that oil security is efficiently produced, it is to avoid because cementing quality is not in drilling process
Cause casualties and property loss well.
