Abstract

The Paratunsky geothermal field has been in operation since 1964, mostly in a self-flowing mode, with a discharge rate of approximately 250 kg/s of thermal water at temperatures of 70‒90°С (47 MW, with the waste water having a temperature of 35°С). The water drawn from the field is used for local heating, spa heating, and for greeneries in the villages of Paratunsky and Termal’nyi (3000 residents). The potential market of thermal energy in Kamchatka includes Petropavlovsk-Kamchatskii (180 000 residents), Elizovo (39 000), and Vilyuchinsk (22 000). The heat consumption in the centralized heating systems for Petropavlovsk-Kamchatskii is 1 623 000 GCal per annum (216 MW). A thermohydrodynamic model developed previously is used to show that the Paratunsky geothermal reservoir can be operated in a sustainable mode using submersible pumps at an extraction rate of as much as 1375 kg/s, causing a moderate decrease in pressure (by no more than 8 bars) and temperature (by no more than 4°С) in the reservoir. Additional geothermal sources of heat energy may include the Verkhne-Paratunsky and Mutnovsky geothermal fields.

使用Paratunsky地热田为堪察加半岛供热

摘要

自1964年以来，帕拉通斯基（Paratunsky）地热田一直以自流模式运行，在70 90°С（47 MW）的温度下，排热水量约为250千克/秒的热水，温度为35°С）。从田间抽出的水用于当地供暖，温泉供暖以及Paratunsky和Termal'nyi村（3000名居民）的绿化。堪察加半岛的热能潜在市场包括彼得罗巴甫洛夫斯克-堪察加（18万居民），埃利佐沃（39 000）和维留琴斯克（22000）。Petropavlovsk-Kamchatskii的集中供热系统的热量消耗为每年1623000 GCal（216兆瓦）。先前开发的热流体动力学模型用于显示Paratunsky地热储层可以使用潜水泵以高达1375 kg / s的抽气速率以可持续的方式运行，从而导致压力适度下降（不超过8巴） ）和温度（最高不超过4°С）。其他的地热热能来源可能包括Verkhne-Paratunsky和Mutnovsky地热田。
