Zhejiang oilfield's first geothermal well test the water
China oil network news at the end of August, Zhejiang oilfield first geothermal wells 102 wells to successfully test the water. In only 7 days, the Zhejiang oilfield has completed the design, preparation, preliminary preparation, drilling, drilling and perforating. This result proves that the northern Jiangsu region has good geothermal resources base, and provides a powerful data support for the further development of geothermal wells.
Field data show that the wells of geothermal resources development and utilization purpose layer temperature of 88 degrees Celsius, stratified test mode, up to now has been completed second layers of water, the wellhead temperature of 68 degrees Celsius, sunrise liquid 280 cubic meters, 700 cubic meters of accumulated liquid.
The design of the well is carried out by air lift test with air compressor. It needs to monitor the downhole pressure and temperature in real time. The process is the first application in Northern Jiangsu Province, and the oil production plant in Northern Jiangsu province attaches great importance to the implementation. In order to speed up the organization, both parties formed a joint research group task decomposition, the nearest fast, separately to implement the equipment resources, and the underground pressure air compressor, direct reading meter, mineral composition analysis and other key work focus tracking, in August 25th the successful completion of all the preparatory work before the test.
The day before, the national development and Reform Commission, the National Energy Bureau, Ministry of land and resources jointly issued the first five year plan of geothermal energy development and utilization of geothermal energy, "" 13th Five-Year "plan". The plan, "13th Five-Year" period, China will add geothermal heating (cooling) area of 1 billion 100 million square meters, to 2020, geothermal heating (cooling) area has reached 1 billion 600 million square meters. Strengthening the exploitation and utilization of geothermal resources is of great significance to the sustainable development of Northern Jiangsu province.
In July, Zhejiang oilfield has completed the pilot project of photovoltaic power generation in Northern Jiangsu province. The breakthrough of the geothermal utilization project is a new progress made by Zhejiang oilfield in the field of new energy development and utilization.
