The utility model is used for adjusting stratum profile craft for an oilfield flooding well on the sea and on shore, and addition agent can be fully swelled and continuously injected in a pipeline. The device comprises an online swelling part and an addition agent injection part which are connected by a swelling pipeline. The utility model does not have a polymer dissolving system, and the polymer is fully swelled and evenly dissolved in the pipeline. The utility model has the advantages of simple procedure, small area occupation and convenient and fast installation and move, and the utility model can be arranged on an offshore platform and realizes online swelling and continuous injection. The utility model has positive function in improving offshore water drive development effect, and changes the original mode of a shipborne injection device. The use cost of an original boat is saved, a series of questions brought by the original boat are solved, and the manufacture cost is reduced.
Description
Technical field
The utility model belongs to the continuous injection device of the online swelling of the oil production equipment of petroleum industry, particularly polymer, is used for marine and onshore oil field water injection well adjustment stratigraphic section technology, and blocking agent swelling in pipeline is injected continuously.
Background technology
At present, offshore oilfield faces oil reservoir serious heterogeneity, moisture fast rise two big contradictions, high permeability zone injects the invalid circulation of water, influence the water drive development effectiveness, adopt profile control technique to carry out effective shutoff to high permeability zone, adjust intake profile, enlarge the water drive swept volume, improve the water drive development effectiveness.The profile control of offshore oilfield water injection well mainly uses the boat-carrying form of construction work, because offshore platform space, weight capacity are limited, the profile control injection device integral body that land is used is arranged on the platform, is unpractical.Use the boat-carrying form of construction work, run into bad weather, consider safety factor, construction team can only withdraw, and cause and can not realize continuous construction, the stifled construction effect of transferring of influence, cost of production is high.Moreover original profile control injection device flow process complexity, profile controls such as polymer must dissolve in dissolution system earlier with material, and are underground by the high head injection pump injection again, strengthened the use amount of profile controls such as polymer with material.
Summary of the invention
The purpose of this utility model provides the continuous injection device of the online swelling of polymer, changes existing injection technique and can not inject the present situation of construction continuously.Make injection device and injection technology practical rationally, realize that online swelling injects continuously, improve the stifled construction effect of transferring.
Use the present technique solution can reach above-mentioned purpose: the continuous injection device of the online swelling of polymer comprises that online swelling part and auxiliary agent inject part, and online swelling part is injected part with auxiliary agent and is connected by the swelling pipeline.
Compared with prior art carry out polymer water plugging and profile controlling technology and have following significant advantage with the utility model:
1, do not have the polymer dissolution system, polymer is abundant swelling in pipeline, uniform dissolution.Owing to removed in the injection allocation process easily polymer solution is caused the capital equipment of shearing such as high pressure polymerisation thing injection pump etc., system is reduced greatly to the shear degradation of polymer solution, thereby also reduced the consumption of polymer.Realized that on-the-spot real-time modulation, scene inject continuously.
2, flow process is simple, floor space is little, can be installed on the offshore platform, not limited by weather, realizes that online swelling injects continuously.Make offshore oilfield realize that heavy dose of deep profile controlling becomes possibility, guaranteed marine profile control test effect, played positive effect improving marine water drive development effectiveness.
3, owing to changed the mode of boat-carrying injection device in the past, save the usage charges of boats and ships and a series of problems of using boats and ships to bring, reduced cost of production.
4, this device not only can be used for offshore oilfield water injection well chemistry deep profile controlling technology, also can be used for onshore oil field water injection well chemistry deep profile controlling technology.Since device simple in structure, main equipment is few, but skid, repeated use, it is quick that convenient removal is installed.
