Shandong Yikuang Drilling Technology Co., Ltd. produces all kinds of geological drill pipes, spiral drill pipes, triangular heavy-duty grooved drill pipes, special-shaped multi-angular grooved drill pipes, coal drill pipes, drill bits, drill pipes, etc., with complete specifications! Strength manufacturers, trustworthy! The company integrates research and development, production, sales and after-sales. Customers are welcome to purchase. Telephone: 0635-2311078. As a new geothermal resource, high-temperature dry hot rock can be widely used in power generation, heating, strengthening oil exploitation and other fields. If technological breakthroughs are achieved, large-scale development and utilization of dry hot rock will effectively reduce the greenhouse effect and the impact of acid rain on the environment. The cost of dry hot rock power generation is only.
As a new geothermal resource, high-temperature dry hot rock can be widely used in power generation, heating, enhanced oil exploration and other fields. If technological breakthroughs are achieved, large-scale development and utilization of dry hot rock will effectively reduce the greenhouse effect and the impact of acid rain on the environment. The cost of dry hot rock power generation is only half that of wind power, which is the cost of solar power generation.1/10. From the last century70Beginning in the 1990 s, many countries around the world have been conducting experimental studies on the development and utilization of hot dry rocks.
At present, the United States, Britain, Australia and other countries have established a number of experimental research bases for development and utilization. The United States has initially carried out experimental power generation of dry hot rock in some areas, and the commercial development of dry hot rock is still in the exploratory stage.
The use of dry hot rock is mainly three aspects：
The first one we have been talking about just now is power generation. Because dry hot rock if you play well, the highest temperature can reach650 degrees, general2,300The degree of resources is relatively common, according to the current technology.2,300Degree, we use it to generate electricity without too much problem, but the scale cannot be too large, mainly distributed power generation, the waste heat of power generation can also be used for heating, dry hot rock itself can also be used for heating, this is its second largest use, heating, heating, dry hot rock can also provide industrial steam, so it has a great potential in heating. In addition, many of our hot dry rocks are actually near the oil fields. During the exploitation of the oil fields, if we want to heat the rocks at the underground head of the oil fields, our oil production will increase greatly.
Of course, in addition, dry hot rock has more uses, such as our refrigeration, we now a lot of refrigeration can use absorption chillers, absorption chillers as long as100 more than degrees or with hot water90Many degrees of hot water can be cooled, some dry hot rock temperature is relatively low, we use it for heating in winter, and it can be used for cooling in summer. China is just getting started,Yiguang Technology Shandong Yiguang Drilling Technology Co., Ltd. produces various geological drill pipes for drilling engineering., spiral drill pipe,Triangular heavy grooved drill pipe,Special-shaped multi-edge grooved drill pipe, coal drill pipe,Drill,Drill pipe, etc., complete specifications!Strength manufacturers,Trustworthy!Company set research and development-Production-Sales-After-sales as a whole, welcome customers to purchase.Although we were in the last centuryThe exploration and development of geothermal has been carried out since the 1970 s, and the research on dry hot rock has not stopped, but this time the dry hot rock has been found and a breakthrough has been achieved. It should be said that the significance is still very significant.
The next step is to invest more money to promote this. In addition to some institutions such as the Ministry of Land and Resources, our big brothers such as PetroChina, Sinopec, and CNOOC should also put more energy into the development of geothermal, because this is after all a development direction for you in the future.
I also conducted this discussion with Academician Wang Jiyang, a very famous geothermal expert in China. Academician Wang is very optimistic about geothermal, but he thinks that we should treat such a technology objectively and calmly. This resource is indeed very good, and the amount of resources is indeed very large, but there is still a long way to go before it can be truly used, we need to make more efforts and more enterprises to participate. Therefore, we must promote the development of this resource, we must use an open market environment, and we must advocate more companies to participate in its exploration and development.
