介绍了千12块的储层地质特征,地球水化学测温测压的技术原理,给出了千12块63-447、65-447、64-48、66-48等4口井在蒸汽吞吐第5轮次过程中温度压力变化结果。对比TP-9000型4参数测试仪测试结果表明:地球水化学测温测压技术可提供相对准确的生产动态参数(如吞吐过程中油藏的温度、压力等),且可实现不关井、不停产、不起下管柱、连续大面积的测试,及时准确地为油田高效开发提供理论依据。

This paper introduces the geologic features of Qian 12 unit, the principles of earth hydrochemistry temperature and pressure measuring technology, and presents the tetn-perature and pressure variations during fifth steam soaking in wells 63-447, 65-447, 64-48 and 66-48 in Qian 12 unit. Comparing with the measuring results obtained from TP-9ooo four-parameter measuring device, it indicates:the earth hydrochemistry temperature and pressure measuring technology can provide relatively accurate production behavior pa-rameters(for example, the temperature, pressure and so on of the reservoir during steam soaking), can realize measurement without shutting in, without pulling and dropping tubing strings, and can provide theoretical basis accurately and in time for the efficient development of an oil field.
