Abstract
The utility model relates to a kind of Tubing protector; especially the long-acting anode Tubing protector of edge in a kind of; this Tubing protector comprises top connection, adapting pipe body, long-acting anode and lower sub; described top connection is connected with adapting pipe body two ends respectively with lower sub, and described long-acting anode is arranged in the adapting pipe body.The utility model can prevent effectively and the corrosion damage and the fouling that slow down the flow string inwall that the utility model use simultaneously is extremely convenient, simple with replacing, and cost is low, and input-output ratio is big, benefit return rate height.
Description
One, technical field
The utility model relates to a kind of Tubing protector, the long-acting anode Tubing protector of especially a kind of interior edge.
Two, background technology
In oil recovery process, at oil and water well oil pipe serious corrosion and scale problems, the sfgd. of taking usually at present is to inject inhibiter in oil and water well.Though this method can be slowed down the corrosion of profit well casing bar to a great extent, but because corrosion factor complexity in the oil and water well, microbe species is various, or else they produce antibody with the difference of environment with stopping and develop, therefore be difficult to the concentration that the control inhibiter adds, can not effectively carry out anticorrosion oil pipe thereby both caused waste to improve cost.
Three, utility model content
The utility model is for solving the above-mentioned technical problem that exists in the background technology, and provides a kind of cost low and can carry out effective rot-resistant Tubing protector to oil pipe.
Technical solution of the present utility model is: a kind of Tubing protector; its special character is: this Tubing protector comprises top connection 1, adapting pipe body 4, long-acting anode 3 and lower sub 5; top connection 1 is connected with adapting pipe body 4 two ends respectively with lower sub 5, and long-acting anode 3 is arranged in the adapting pipe body 4.
The without hindrance mode of edge was connected with adapting pipe body 4 in above-mentioned long-acting anode 3 adopted.
4 of above-mentioned long-acting anode 3 and adapting pipe bodies are provided with high efficiency packing 2.
Above-mentioned high efficiency packing 2 is four sections.
Above-mentioned Tubing protector is tied with the insulation tape wrap outward.
Above-mentioned top connection 1, lower sub 5 are adopted clamping, are threaded or fixedlyed connected with 4 of adapting pipe bodies.
The utility model is a kind of technology that principle of cathodic protection is carried out electrochemical anti-corrosive of using; its metal alloy that a kind of current potential is more negative is connected with oil pipe as sacrificial anode; when operation and oil pipe RIH together; oil pipe and sacrificial anode are in and constitute a new macroscopical battery under the same electrolyte environment; negative potential is the anode of new macroscopical battery; oil pipe then becomes negative electrode; from anode bodies, provide a cathodic current to oil pipe by ionogen; make oil pipe carry out negative electrodeization; thereby realization galvanic protection; therefore the utility model can effectively prevent and the corrosion damage and the fouling that slow down the flow string inwall; the utility model use simultaneously is extremely convenient with replacing; simply; cost is low, and input-output ratio is big, benefit return rate height.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, embodiment
Referring to Fig. 1, the utility model comprises top connection 1, adapting pipe body 4, long-acting anode 3 and lower sub 5, adapting pipe body 4 adopts the material suitable with J55 oil pipe grade of steel to make, top connection 1 is connected with adapting pipe body 4 two ends respectively with lower sub 5, its mode of connection can adopt flexible connection or fixedly connected, specifically decide on Working environment, movable connection method is connected to suitable threadably, specifically can adopt the API standard thread.Top connection 1 and lower sub 5 are special for cooperating oil pipe to be connected, the oil pipe of use when concrete and deciding.Long-acting anode 3 is arranged in the adapting pipe body 4, the without hindrance mode of edge was connected with adapting pipe body 4 in it adopted, inner extruding connecting portion is appeared to hold and is adopted minor insulation, 4 of long-acting anode 3 and adapting pipe bodies are provided with high efficiency packing 2, high efficiency packing is good with four sections, and high efficiency packing can be guaranteed the electric current uniform distribution.Tubing protector is tied with the insulation tape wrap outward, and the insulation tape wrap guarantees that ionic normally exchanges.
The utility model is equivalent to the tubing pup joint of a lengthening, can be connected any position of oil pipe, is lowered to pit shaft with oil pipe.During use; the adding inhibiter can adopted; in the time of corrosion protection coating; adopt protected mode of the present utility model to strengthen anticorrosion to the oil pipe bar to the oil pipe bar again; utilize the comprehensive regulation to reach the anticorrosion purpose of oil and water well oil pipe bar, simultaneously model, quantity of the present utility model and the loading position of selecting long-acting anode 3 according to the corrosive environment and the degree of oil and water well.
