南海某区岩石物理测试及规律分析

为了解决南海某勘探区目前存在的地球物理问题，选取了27块岩心，设计了针对样品岩石骨架、饱和流体（水，油和气）、变温变压以及变饱和度等四种类型实验，进行了岩石物理测试。得到P型、S型以及C型组合参数等3类岩石物理数据。利用测试的岩石物理数据，分析了该区岩石物理参数受温度、压力等地层环境的影响，明确了该区流体类型对岩石物理参数的影响情况，并建立了该区岩石物理参数对流体的敏感性序列，讨论了不同流体饱和度对岩石物理参数的影响，最终建立了该区岩石物理参数模板，为该区储层预测和油气检测研究提供指导。

Petrophysical testing and rules analysis in some exploration area of South China Sea

Aiming at solving the geophysical problem in some exploration area in South China Sea, 27 cores were used to perform the petrophysical testing including the four types of experiments as follows： rock sample skeleton, saturated fluid （water, oil and gas）, varying temperature ＆ pressure and varying saturation. Therefore, three types of petrophysical datas of P-, S- and C-type combination parameters were obtained. With the measured data, this paper discussed the influence of stratum environment （i.e. tem- perature and pressure） on petrophysical parameters, clarified the impact of fluid types on petrophysical parameters and built up the sequence of fluid-sensitivity of petrophysical parameters in the area. Finally, the effects of various fluids＇ saturation on the petro- physical parameters were discussed and the petrophysical parameterers template in the work area was eatablished, which would be helpful in guiding the work of reservoir prediction and oil ＆ gas testing research.
