基于MFC应用程序基本框架的CH4-H2O-NaCl体系包裹体PVTx计算软件开发

摘要

Fluid inclusions including CH4-H2 O-NaCl system are widespread in reservoirs, and their parameters of P-V-T-x are very important for determining hydrocarbon accumulation stage and process. Since the calcula-tion of above parameters is complicated, the automatic calculation of parameters using computer program is often used by geologists. By means of the PVTx calculation software for CH4-H2O-NaCl system in fluid inclusions based on Microsoft Foundation Class (MFC) program frame, the homogenization pressure in CH4-H2O-NaCl system in fluid inclusions are automatically calculated according to indoor temperature, homogenization tempera-ture, ice temperature and Raman shift of fluid inclusion. The calculation results are directly showed in the P-T phase diagram and the gas-liquid saturation curve is obtained in the situation. The software in calculating is quick and perfect, and affords important consult in choosing tool and language for developing processing software of homogenization temperature of fluid inclusion.%储层中CH4-H2 O-NaCl体系包裹体广泛存在，其PVTx参数是了解油气成藏期次、探讨成藏过程的重要依据。由于上述参数的计算过程繁琐复杂，利用计算机程序自动计算参数成为国内外地质学家普遍采取的手段。基于微软的MFC类库及其应用程序框架开发的CH4-H2 O-NaCl体系包裹体PVTx计算软件，通过室温、包裹体均一温度、包裹体冰点温度以及包裹体拉曼位移的具体实验检测数据，自动计算输出CH4-H2 O-NaCl体系包裹体均一压力，同时，能够将计算结果直观地表示在P-T相图中，得到在该组成条件下的气-液饱和曲线。该软件计算快速准确，界面友好，拓展性强，为包裹体测温数据处理软件开发在选择开发工具和语言上提供了参考。
