Abstract
A thermal recovery ram preventer comprises a middle flange on the side surface of a housing, a disc shaft driven by a piston, and a disc assembly, and is characterized in that a cooling cavity is arranged between a piston cylinder accommodating the piston and the middle flange. Circular cooling water (liquid) is injected into the cooling cavity from the outside of the thermal recovery ram preventer, so as to safely isolate heat quantity of well liquid and control system hydraulic oil in the piston cylinder for guaranteeing safe operation of a control system.
Description
[technical field]
The utility model is a kind of thermal recovery ram preventer, is installed in thermal production well mouth, the well kick that prevention stratum high pressure band of gas crude oil and water may form and the generation of blowout.
[background technology]
Thermal recovery technology is widely used in the collection of oil-field thick-oil and underground heat, because thermal recovery technology all needs to carry out in hot environment, common preventer can't adapt to.For head it off, except the resistance to elevated temperatures that improves the preventer encapsulant, need prevent that also the heat of well liquid is delivered to the oil pocket of blowout preventer hydraulic cylinder, guarantee the trouble free service of control system.
[summary of the invention]
The technical scheme that the utility model adopts cooling chamber to isolate stops the heat of well liquid to be delivered to the oil pocket of blowout preventer hydraulic cylinder, and hydraulic fluid temperature is no more than the design temperature of control system in the preventer, guarantees that thermal recovery is working properly to carry out.
The technical solution of the utility model is: a kind of thermal recovery ram preventer, comprise the spacer flanger of housing side, by flashboard axis and flashboard assembly that piston drives, and it is characterized in that holding between the piston cylinder of piston and the spacer flanger and be provided with cooling chamber.
In the such scheme, inject the cooling water (liquid) of circulation to cooling chamber from thermal recovery ram preventer outside, can separate the control system hydraulic oil in the heat of well liquid and the piston cylinder safely, guarantee the safe operation of control system.
[description of drawings]
Accompanying drawing is the structural representation of thermal recovery ram preventer.
[specific embodiment]
Be further described below in conjunction with embodiment of the present utility model and accompanying drawing thereof.
Thermal recovery ram preventer as shown in drawings, the flashboard axis 1 and the flashboard assembly that comprise the spacer flanger 4 of housing side, drive by piston 5, characteristics of the present utility model are to be provided with cooling chamber 3 between piston cylinder 2 that holds piston 5 and spacer flanger 4, and other structures and common preventer are as good as.Can dispose cooling medium such as water in the cooling chamber 3 according to regular circulation, take away heat, make the heat of well liquid in the preventer body the least possible be delivered to control system, comprise flashboard axis 1, piston cylinder 2, piston 5 and hydraulic pressure wet goods, guarantee the safe operation of control system.
Claims (1)
1. thermal recovery ram preventer comprises the spacer flanger of housing side, by flashboard axis and flashboard assembly that piston drives, it is characterized in that holding between the piston cylinder of piston and the spacer flanger being provided with cooling chamber.
