GEOTHERMAL RESOURCES SURVEY IN KAMCHATKA PENINSULA

堪察加半岛分布着29座活火山，具有两大火山链。堪察加半岛地热田活跃，部分地热田已被勘探开发。Paratunsky和Malkinsky地热田的地热流体位于Ptropavrovsk-Kamchatsky（P/K）附近，用于温泉，鲑鱼养殖场和农业养殖。Mutnovsky地热田位于P/K西南方向120公里处。约在现场开挖了90个钻孔，然后运行了12 MW的试验电厂。在不久的将来，将生产40 - 50 MW的电力，主要在Dachny现场。Mutnovsky地热田的地质构造为N-S方向的反构造和NE-SW方向的雕刻构造，断裂构造也与一般地质构造一样具有两个方向。地热流体的最高温度为300℃，等温线位于海平面以下750 m处。在扰动岩体周围估计了上升气流区，认为扰动岩体是本区的热源。地热储层规模，流体焓1270-1390 kJ/kg，南北向5 km，东西向3 km，埋深2 km。该地区的最佳容量被认为是72千瓦。

Twenty-nine active volcanoes with two major volcanic chains are distributed in Kamchatka Peninsula. There are many active geothermal fields in Kamchatka Peninsula, and some of them are explored and developed. Geothermal fluids of the Paratunsky and Malkinsky geothermal fields, which are located near Ptropavrovsk-Kamchatsky (P/K), are supplied for hot spring, salmon farm and agricultural farming. The Mutnovsky geothermal field is located 120 km from P/K in southwest direction. Ca. ninety drills have been excavated in the field, and then pilot power plant of 12 MW is operating. In near future, 40 - 50 MW electric power, mainly in the Dachny site, will be produced.Geological structure of the Mutnovsky geothermal field is antic-structure in N-S direction, and graven structure in NE-SW direction, and fault structure also shoes two directions as the same as general geological structure. The estimated maximum temperature of geothermal fluid is 300℃, and isotherm is located 750 m below sea level. Up flow zone is estimated around the diorite intrusion, which is considered as a heat source of this area. The dimension of geothermal reservoir, with fluid enthalpy of 1270-1390 kJ/kg, 5 km NS, 3 km EW and 2 km depth. The optimum capacity of the area is considered as 72 kW.
