温度场、压力场、能量场和应力场是流体动力场研究的主要内容。现今温度场一般根据钻井实测地温及大地热流测试确定,古地温场主要依据包裹体均一温度确定。压力场的研究方法颇多,主要有声波测井、实测地层压力和地震层速度方法,前两种方法主要应用于已钻探区,后者则重点应用于非钻探区。在进行能量场分析时,应注重在三维烃源岩体和流体输导体系发育的格架下,恢复古流体势。通常情况下,应力值较大的地域,其流体压力值也较高,对某一具体地区而言,首先应划分单井纵向压实-压力带,然后划分压力系统,最后进行正演模拟,探讨压力形成机制。地下流体动力场之间存在着互相联系、彼此耦合的关系,因此,须用整体的观点系统研究。
Temperature field, pressure field, energy field and stress field are the main contents of fluid dynamic field research. Nowadays, the temperature field is generally determined according to the measured ground temperature and the earth heat flow test. The paleogeothermal field is mainly determined by the homogenization temperature of the inclusions. There are many research methods of pressure field, mainly acoustic logging, measured formation pressure and seismic velocity method. The first two methods are mainly applied to the drilled area, the latter are mainly applied to the non-drilling area. In the analysis of energy field, attention should be paid to restoring paleo-fluid potentials under the framework of the development of three-dimensional source rocks and fluid transport systems. Generally, the stress value of the larger area, the fluid pressure value is also higher, for a specific area, we should first divide a single longitudinal compression - pressure zone, and then divide the pressure system, and finally forward modeling, Explore the mechanism of stress formation. Underground fluid dynamic field exists between the interconnected and coupled relationship, therefore, must use a holistic perspective systematic research.
