Abstract
The utility model relates to an antiwax tube, in particular to a solid chemical flow-disturbing antiwax tube for downhole operation. The utility model is characterized in that the utility model comprises a body (3) of the antiwax tube in which filling materials (4) are arranged. Aiming at the problems in the background technique, the utility model is provided with a flow-disturbing antiwax tube with a long serviceable life, a good weatherability and a low cost that can effectively prevent the oil tube from paraffinning.
Description
Technical field
The utility model relates to a kind of anti wax pipe, the Solid-state Chemistry flow-disturbing anti wax pipe of especially a kind of down-hole effect.
Background technology
In oil recovery process, at the tubing wax problem, common solution is to inject chemical paraffin inhibitor in oil-water well at present.Though this method can be slowed down tubing wax to a great extent, but because the influence of natural environment, human factor and technical limitation, the effect of this anti-wax technique is periodically very short, weatherability is very poor, in order to reach the effect that continues wax control, injection chemical paraffin inhibitor that just must continuous and quantitative, the operation cost in the time of will causing like this utilizing this kind wax control mode wax control is very high.
The utility model content
The utility model is for solving the above-mentioned technical problem that exists in the background technology, and the flow-disturbing anti wax pipe that a kind of life cycle length, good weatherability, cost are low, can effectively prevent tubing wax is provided.
Technical solution of the present utility model is: the utility model is a kind of anti wax pipe, and its special character is: this anti wax pipe comprises anti wax pipe body 3, is provided with filler 4 in the anti wax pipe body 3.
Above-mentioned filler 4 is that the without hindrance formula of interior edge is connected with the connected mode of 3 of anti wax pipe bodies.
The filling mode of above-mentioned filler 4 is a filling type or fixed.
Be provided with flow-disturbing bar 5 in the above-mentioned filler 4.
The two ends of above-mentioned anti wax pipe body 3 are respectively arranged with the fixedly baffle ring 2 of filler 4.
Above-mentioned anti wax pipe body 3 two ends are respectively arranged with union 1.
Above-mentioned anti wax pipe body 3 adopts the movable connection method or the mode of fixedlying connected with 1 of union.
The movable connection method of 1 employing of above-mentioned anti wax pipe body 3 and union is for being threaded.
The utility model solves the technical problem of tubing wax by the anti wax pipe that is provided with high efficiency packing in the down-hole, its high efficiency packing has the chain link with the alkane structural similarity, the polar group that has some again, it is dissolved in the oil, produce the eutectic effect with the wax in the crude oil, suppress the growth of wax crystalline substance then by the polar group outside extending in, thereby the wax deposition of oil well is reduced, reach the effect of wax control, so the utility model can effectively prevent and slow down the tube inner wall wax deposition; The utility model places high efficiency packing in the anti wax pipe body simultaneously, be provided with union at the anti wax pipe two ends, so its construction is simple, safe and reliable, life cycle is long, greatly reduces the cost of wax control.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, be provided with filler 4 in the anti wax pipe body 3 of the present utility model, filler 4 is that the without hindrance formula of interior edge is connected with the connected mode of anti wax pipe body 3.The filling mode of this filler 4 can also can be a filling type for fixed.Also be provided with flow-disturbing bar 5 in filler 4, flow-disturbing bar 5 is used for making filler 4 fully to dissolve, and the two ends of anti wax pipe body 3 are respectively equipped with the fixedly baffle ring 2 of filler 4, and the two ends of anti wax pipe body 3 also are respectively arranged with union 1.Union 1 links to each other with anti wax pipe body 3 two ends, and its connected mode can adopt movable connection method or fixedly connected mode, specifically decides on working environment, and movable connection method is connected to suitable threadably, specifically can adopt the API standard thread.Joint 1 is special for cooperating oil pipe to connect, and is decided by oil pipe when specifically using.
The utility model can be connected the following any position of pump barrel of flow string; be lowered to pit shaft with oil pipe; during use; according to the wax deposition environment of oil pipe and the quantity and the loading position of degree selection anti wax pipe; adopt the protected mode of using anti wax pipe to prevent or reduce the wax deposition of oil pipe to oil pipe, utilize the comprehensive regulation to reach the purpose of oil-water well oil pipe wax control.
