Abstract
The invention discloses an axial vibratory impulse well cementation method and device, especially suitable for well cementation of an oil well with relatively high well cementation quality requirement. The method comprises the following steps: firstly, adjusting the parameters of a throttle valve and an elastic impact hoop of an axial vibratory impulse well cementation device (3) in a pit according to the characteristics and the well cementation requirements of a well body; secondly, lowering the axial vibratory impulse well cementation device (3), a float shoe (1) and a float collar (2) to the well depth of design along with a casing string (4), performing well cementation according to a normal program after putting in place, enabling the casing string (4) to generate axial vibration under the action of the axial vibratory impulse well cementation device (3), enabling a colliding pressure rubber plug to generating colliding pressure at the top of the axial vibratory impulse well cementation device (3) when cement reaches the cement top of design, and waiting for cementing, so that the well cementation operation is finished. According to the well cementation method and device, the axial impulse vibration can be generated and the vibration distance is long and can reach 500 m; the pressure of the whole well section orderly fluctuates, so that the substitution effect can be improved and the well cementation quality is high; the device is simple in structure, and the process is convenient, safe and reliable to implement.
Description
Technical field
The present invention relates to a kind of axial vibration pulse cementing method and device thereof, be specially adapted to the oil well cementing construction that cementing quality requirement is higher.
Background technology
The benefit of vibration cementing: 1. vibration frequency is when 150 ~ 200Hz, the intensity of Behavior of Hardened Cement Paste can improve 15%; 2. under the oscillator field effect of 50Hz, drilling fluid viscosity reduces by 20 ~ 30%, and on sleeve pipe, residual drilling fluid reduces 50%, also helps and removes borehole wall filter cake; 3. can greatly reduce cement paste gel strength, make cement paste keep head of liquid, be conducive to the intrusion preventing formation fluid, avoid altering groove; 4. the bonding quality at interface is increased.At present, a kind of vibration cementing method of on-the-spot application adopts ground vibration mode, although can realize the vibration of full well section, device, complex process; Another kind method is the radial vibration device adopting a kind of eccentric hammer, cement paste by time produce eccentric vibrating, feature be radial disbalance vibration, oscillation distances is short, limited efficiency.
Summary of the invention
The invention provides a kind of axial vibration pulse cementing method and device thereof, its equipment is simple, can produce axial vibration, increases oscillation distances, improves the cementing quality of full well section.
The present invention is achieved in that first according to well bore feature and cementing requirements, the choke valve of axial vibratory impulse cementing unit and the parameter of elastic impact hoop under adjust well, then by axial vibration pulse cementing unit, float shoe together with float collar, with arriving design well depth under casing string, cement the well by normal procedure after putting in place, under the effect of axial vibration pulse cementing unit, casing string produces axial vibration, when cement reach design return high time, bruising plug is in the top bruising of axial vibration pulse cementing unit, Hou Ning, completes cementing operation.Under the effect of axial vibration pulse cementing unit, tubing string oscillation distances reaches 500 meters, also makes whole well cementation produce the pressure of full well section and the pulse feature change of flow velocity simultaneously, thus improves cementing quality.
A kind of special purpose device of use of axial vibration pulse cementing method, it is made up of body, turbine rotor, an elastic impact hoop is provided with on turbine rotor top, an eccentric throttle valve is provided with in turbine rotor bottom, local towards when injecting cementing concrete, cementing slurry makes turbine rotor rotate, turbine rotor drives eccentric throttle valve to rotate, when the area of passage that the different angles of rotating are just corresponding different, different effects of damming makes the axial play of turbine rotor, on huge impact force action rotor top elastic impact hoop, drive tubing string axial vibration.
The present invention can produce axial impulse oscillation, and oscillation distances can reach 500 meters greatly; Full well section pressure fluctuates in order, can improve replacement effect, thus it is high to improve cementing quality; Structure of the present invention is simple, and process implementing is convenient, safe and reliable.
