Abstract
A set of well cementing equipment comprises a slurry mixing system and a slurry injection system. The slurry mixing system comprises a centrifugal pump. The slurry injection system comprises a well cementing plunger pump. The well cementing equipment further comprises the following components: a driving motor which is used for driving the centrifugal pump, and a driving mechanism which drives the well cementing plunger pump. In the slurry mixing system of the well cementing equipment, a hydraulic driving motor is adopted for driving. Relatively to a diesel engine, the caused displacement fluctuation of the centrifugal pump is smaller so the slurry mixing density is smoother thereby obtaining higher strength of the solidified cement and obtaining a purpose of improving the well cementing effect.
Description
Technical field
The utility model relates to a kind of petroleum machinery equipment, particularly a kind of cementing equipment.
Background technology
Cementing equipment is to be used for carrying out the equipment that cement paste mixes slurry and infusion in the well cementing operation process.Cementing equipment generally includes auxiliary automatically controlled, gas control of the slurry system of mixing, filling system and other and hydraulic control system.Filling system adopts diesel engine to drive fluid torque-converter usually, drives the power transmission mode of well cementation plunger displacement pump again by shaft coupling.And mix slurry system and the shared diesel engine of filling system, by Diesel Driven hydraulic motor and hydraulic jack, thereby drive each centrifugal pump, agitator and the ash discharging valve that mixes in the slurry system.
Yet, because the diesel engine speed fluctuation range is big, should not accurately control, cause the centrifugal pump flow oscillation big, mix the pulp density instability, influence well cementation effect.
Summary of the invention
In view of this, be necessary to provide a kind of cementing equipment that improves the well cementation effect.
A kind of cementing equipment, comprise and mix slurry system and filling system, described mixed slurry system comprises centrifugal pump, and described filling system comprises the well cementation plunger displacement pump, and described cementing equipment also comprises and is respectively applied for drive motors that drives centrifugal pump and the driving mechanism that drives the well cementation plunger displacement pump.
