油田开采时应用氚的氧化物——氚水作为油田注水的指示剂。由于氚水实际上不被岩石所吸附、便宜、放射毒性很低又不产生外照射,因而研究范围在不断扩大。为此,应对此项工作的辐射情况和辐射安全措施加以研究。把指示剂注入所要研究的油层有二种方 Oilfield exploitation of tritium oxide - tritiated water as an indicator of water injection. As tritiated water is practically not adsorbed by rock, it is cheap, has low radiotoxicity, and does not generate external radiation, so the scope of the study is constantly expanding. To this end, research should be conducted on the radiation situation and radiation safety measures for this work. There are two ways to inject the indicator into the reservoir to be studied
