The utility model is achieved like this in order to achieve the above object: the dual cavity delivery device of oil gas well active metal wax removal de-plugging rod, mainly by last lubricator, box cupling and plug, down lubricator, connect valve and mobile water injecting pump, high-pressure hose, snap joint, pressure meter and atmospheric valve group are formed.It is characterized in that: the top of going up lubricator is equipped with box cupling and plug.Be connected with the connection valve in the lower end of last lubricator.The lower end that connects valve is connected with down lubricator.On last lubricator and following lubricator, be fixed with pipeline respectively, be connected with indicated pressure and antiaircraft pressure meter and the atmospheric valve group that acts on the pipeline.The lower end of following lubricator connects the production tree testing valve.Last lubricator and following lubricator inside form two independently airtight chamber.The production tree test strobe connects the last interface of the little four-way of production tree.The high-pressure rubber pipe of mobile water injecting pump is connected with snap joint on the little four-way of well head.The lower interface of the little four-way of production tree is connected with the production tree master valve, and two side interfaces of the little four-way of production tree have production tree to produce valve.Formed the 3rd independently airtight chamber.Be used with the little four-way of oil gas well production tree, guaranteed to add water and caber does not disturb mutually.
The beneficial effects of the utility model are: the dual cavity delivery device of oil gas well active metal wax removal de-plugging rod, realized adding water and caber does not disturb mutually, can add water continuously, active metal wax removal de-plugging rod and the successive reaction of injecting water have been guaranteed, improve paraffin removal from oil well plugging removal effect and security performance, have be convenient to operation, security performance is good, is convenient to characteristics such as operation.
Description of drawings
Fig. 1 is the theory structure schematic diagram of the dual cavity delivery device of the utility model oil gas well active metal wax removal de-plugging rod;
Among the figure: 1-moves water injecting pump, 2-high-pressure hose, 3-snap joint, 4-pressure meter and atmospheric valve group, lubricator under the 5-, the last lubricator of 6-, the box cupling of the last lubricator of 7-and plug, 8-connects valve, 9-production tree test valve, and the 10-production tree produces valve, the little four-way of 11-production tree, 12-production tree master valve, 13-Christmas tree big four joint, 14-down-hole oil tube.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified its embodiment.
Embodiment 1: consult Fig. 1.The dual cavity delivery device of oil gas well active metal wax removal de-plugging rod is the paraffin removal unit that is connected on the well recovery tree.Mainly form by last lubricator 6, box cupling and plug 7, following lubricator 5, connection valve 8 and mobile water injecting pump 1, high-pressure hose 2, snap joint 3, pressure meter and atmospheric valve group 4.In the bottom of the little four-way 11 of production tree production tree master valve 12, Christmas tree big four joint 13 and down-hole oil tube 14 are arranged.
A box cupling and plug 7 are installed on the top of last lubricator 6.Be connected with one in the lower end of last lubricator 6 and connect valve 8.The lower end that connects valve 8 is connected with a following lubricator 5.On last lubricator 6 and following lubricator 5, be fixed with pipeline respectively, be connected with pressure meter and atmospheric valve group 4 on the pipeline.The lower end of following lubricator 5 connects production tree testing valve 9.Last lubricator 6 and following lubricator 5 inside form two independently airtight chamber.Production tree test strobe 9 connects the last interface of the little four-way 11 of production tree.The high-pressure rubber pipe 2 of mobile water injecting pump 1 is connected with snap joint 3 on the little four-way 11 of well head.The lower interface of the little four-way 11 of production tree is connected with production tree master valve 12, and two side interfaces of the little four-way 11 of production tree have production tree to produce valve 10.Formed the 3rd independently airtight chamber.
The process of manipulating of the present utility model: consult Fig. 1.Before high-pressure oil-gas well being carried out active metal wax removal de-plugging rod delivery construction, the production tree of closing high-pressure oil-gas well two arms produces gate 10, pressure meter and atmospheric valve group 4 be housed, go up the last lubricator 6 of the box cupling of lubricator and plug 7, lubricator 5 and is connected the dual cavity lubricator that valve 8 forms and uses screwed connection to test on the valve 9 down production tree, the high-pressure hose 2 usefulness snap joints 3 of mobile water injecting pump 1 are connected on the little four-way 11 of production tree.Just form three at the well head of high-pressure oil-gas well like this and independently delivered chamber, that is: gone up lubricator 6, lubricator 5 and the little four-way 11 of production tree down.
High-pressure oil-gas well being carried out active metal wax removal de-plugging rod when delivering construction, close production tree test valve 9, open production tree master valve 12, with mobile water injecting pump 1 by high-pressure hose 2 and snap joint 3 injection clear water continuously in well; During caber, open the box cupling of lubricator and the chamber that plug 7 is put into active metal wax removal de-plugging rod lubricator 6, tighten the box cupling and the plug 7 of lubricator, open and connect valve 8 active metal wax removal de-plugging rods by reentering down in lubricator 5 chambers certainly, close and connect valve 8, then open production tree test valve 9 active metal wax removal de-plugging rods by conducting oneself with dignity by behind the little four-way 11 of production tree, production tree master valve 12, the Christmas tree big four joint 13, enter the paraffin blockage position of down-hole oil tube 14, be hampered back and injection water successive reaction reach the purpose of de-plugging.
The clear water that enters oil well has like this been realized separating of pressure system with active metal wax removal de-plugging rod, has guaranteed the successive reaction of clear water and active metal wax removal de-plugging rod, has improved the wax removal plugging removal effect; In operating process, last lubricator remain drying, do not need remaining clear water in the wiping lubricator, reduced the workload of constructing operation, also improved the safety of operation simultaneously.
