Abstract
The utility model relates to a novel microwave-heating paraffin-removing device and belongs to the field of oil production equipment. The device comprises a microwave generator, a wellbore microwave transmission cable and a wellbore microwave receiver. An end socket is installed at a casing exit of a wellhead christmas tree and is used to fix the tip end of the microwave transmission cable. An adaptor is used to connect the microwave transmission cable with the microwave generator. The microwave generator is constituted by a magnetron and an output antenna. The bottom of the microwave transmission cable is connected with the microwave receiver which is immersed in the crude oil under the wellbore. The utility model has the advantages of simple structure, easy operation, reduced consumption of energy and cost, and reduced labor intensity.
Description
Technical field
The utility model belongs to equipments for oil extraction, particularly a kind of producing well heating using microwave wax-proofing apparatus.
Background technology
Crude oil wax, to solidify be the key factor that influences producing well output, perplexs the difficult problem of oil field ordinary production especially.In order to keep the ordinary production of the content of wax, high-solidifiability oil well, multiple clear wax control and pour-point depressing methods such as adopt that machineries, chemistry, electric heating, heat are washed in the production practices, chemistry more clearly wax control then be wherein use comparatively extensive, effect is a kind of preferably.Yet, the chemical paraffin removal and control method of field by using is based on liquid Wax removing agent at present, in the oil well production process, need regularly in well, to add liquid Wax removing agent, thereby oil recovery workman workload and labour intensity are bigger, complex operation, and need to be equipped with plant equipment such as vehicle, cost of production is improved.In recent years, the solid antiwax agent that oil well adopts is still in the anti wax pipe that is placed on the downhole pump below, using the later stage and using under the abnormality, solid antiwax agent deliquescing in the anti wax pipe, intensity reduces, and becomes fine grained chippings, fine grained chippings enters oil well pump, cause the holddown accident, influence wax control result and give full play to, be difficult to guarantee the oil well ordinary production.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of producing well heating using microwave wax-proofing apparatus is provided.
Producing well heating using microwave wax-proofing apparatus of the present utility model is to be made of microwave generator, pit shaft microwave transmission cable and pit shaft microwave receiver.Fix at the sleeve pipe outlet installation end socket of well head production tree and with the microwave transmission cable ends.Crossover sub is connected the microwave transmission cable with microwave generator, microwave generator is to be made of magnetron and output antenna.The microwave receiver that is immersed in the crude oil under the lower end of microwave transmission cable and the pit shaft is connected.
As further improvement of the utility model, the microwave transmission cable is a coaxial cable; Crossover sub is coaxial crossover sub; Microwave receiver is a microwave aerial assembly.Described coaxial cable is that flexible material is made, has realized the microwave transmission that part or small size are remote, have turnover.
Producing well heating using microwave wax-proofing apparatus of the present utility model can be provided with the more than one microwave receiver that places the different depth interval corresponding to the microwave transmission cable in pit shaft.Horizontal well and peupendicular hole all are suitable for this appliance arrangement.
The device structure of producing well heating using microwave wax-proofing apparatus of the present utility model is simple, easy to operate, energy saving economy, alleviated labour intensity.
