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。
The cable formation pressure test measures the formation pressure of the reservoir directly in an open-hole well to obtain formation pressure data. However, due to the structural and fluid properties of the reservoirs, the formation pressure shows a variety of regular changes both vertically and horizontally. In the study of Chengdao multi-reservoir, the data of cable formation pressure logging were used to calculate the oil, gas and water densities according to different fluid properties and different pressures. The oil-water interface was determined and the oil-gas water layer was correctly interpreted. Structure has a special impact on the pressure, analysis of the deposition of non-continuity. In the process of analysis and research, the relevant data, such as oil test and formation dip information, are used to confirm the results. As the Chengdao Oilfield is still in the early stage of development, the formation pressure is primitive. With the further development, the phenomenon of pressure shortfall will become increasingly obvious. Using the formation pressure test data to analyze this phenomenon is both economical and quick. In oilfield development, Will play a more important role.
