电缆地层压力测试资料在埕岛油田的应用研究

电缆地层压力测试是在裸眼井中直接测量储集层的地层压力，以获取地层压力资料。但由于油藏受构造和流体性质的影响，地层压力在纵向和横向上呈现出多种有规律的变化。在埕岛复式油藏研究中，使用电缆地层压力测井资料，根据流体性质对压力产生不同的影响，计算油、气、水的密度，确定了油水界面，正确解释了油气水层；还利用构造对压力产生特殊影响，分析了沉积的非连续性等。在分析和研究过程中，利用相关的资料如试油、地层倾角资料加以证实，从而获得满意的结果。由于埕岛油田还处于开发初期，地层压力是原始的，随着开发进一步深入，压力亏空等现象将会日趋明显，利用地层压力测试资料分析这种现象，既经济又快捷，在油田开发中，必将起到更重要的作用。

Application of formation pressure test data by cable to Chengdao oilfield

To obtain formation pressure data, formation pressure test by cable measures formation pressure of reservoir directly in open hole. But because structure and fluid property have influence on reservoir, formation pressure presents varied regular change longitudinally and transversely. In the research on Chengdao complex reservoir, using formation pressure log data and according to the different influence of fluid property on the pressure, the densities of oil, gas and water are calculated, oil water interface is determined, the intervals of oil, gas and water are interpreted correctly; Using the special influence of the structure on the pressure, depositional uncontinuity is analyzed. During the analysis and research process, correlated data (test data and formation dip data) are conformed, then satisfied result is obtained. Because Chengdao oilfield is at early development period, formation pressure is original. As development goes on, phenomena of pressure deficit will be serious day by day. Analyzing formation pressure test data, is characteristic of quick and economic and will take more important effect on oilfield development.
