Abstract
Description
Technical Field
[0001] The utility model relates to a novel solar hot water circulation oil well dewaxing device, in particular to an oil well underground dewaxing device which utilizes a solar collector to generate hot water and stores it in a hot water storage tank; drives a pipeline circulation pump through an intelligent control part; and connects two symmetrical inlet and outlet circulation loop hot water pipes arranged in a gap cavity between an oil well casing and an oil pipe to form a sealed integral pipeline. Background Art
[0002] At present, the widely used oil well dewaxing technologies mostly adopt electric heating, heating belt, electromagnetic heating, and traditional high-pressure steam dewaxing. The dewaxing effect is not ideal. It not only requires a lot of equipment, vehicles and personnel, consumes a lot of manpower, material resources and electricity, but also has complicated process operations. It needs to be repeated every once in a while, and it is necessary to stop work and production during construction, resulting in serious waste of energy and financial resources and reduced production efficiency. Some dewaxing equipment is also very expensive, which greatly affects the unit oil production efficiency ratio. How to develop a dewaxing equipment with low cost, low use cost, no consumption of conventional energy, no need for repeated shutdowns, can achieve efficient removal of wax, improve oil production efficiency, reduce oil production energy consumption ratio, and better serve oil production; this is the goal of the majority of oilfield production science and technology workers, and it is also the expectation of the majority of oil production workers. Based on this, after years of research, design and planning, we proposed this scheme, namely the design of solar hot water circulation oil well dewaxing device. Summary of the invention
[0003] The utility model provides a solar hot water circulation oil well dewaxing device, which consists of a solar hot water collection and storage part; an intelligent control part; a pipeline circulation pump part; and an underground hot water dewaxing part. The four parts are interconnected to form an integral device. It overcomes the drawbacks of the existing oil well underground dewaxing technical equipment, which is high in cost and complicated in operation process, and each operation requires a large amount of manpower, material and financial resources to be consumed, and the oil production operation needs to be stopped, resulting in a decrease in oil production. The equipment is left underground all year round, and does not require repeated operations to save a lot of manpower and material resources. Automatic dewaxing does not require stopping the oil production operation and does not affect the oil production output. The energy generated by the hot water comes from solar energy, which can generate long-term benefits with a one-time investment, energy saving and environmental protection, and the circulating power pump consumes only a small amount of electricity when it is started, and no energy is consumed at other times. The overall energy-saving and efficiency-enhancing effect is remarkable. It is a necessary equipment for efficient oil production operations of oil wells in major oil fields, with strong market competitiveness and huge social and economic benefits.
