摘　　要：针对天然水体体积计算难题,从水侵量的定义公式出发,以S理想边水驱油藏为例,以廖运涛方法获得的精确解为约束条件,主要是对采用的综合压缩系数进行校正,获得了理想边水驱油藏天然水体体积的简便估算方法,在类似油藏上应用取得了好效果,为选择合适的开发方式提供了重要依据。对于井网完善、已全面投入开发、完全依靠边水补充能量、以自喷为主的高渗透、稀油油藏,在经历几年的开发后有明显的油层压降情况下,只要能够落实清楚总压降值和与之对应的水侵量,就可以估算出天然水体的体积。至于该方法能否拓宽应用范围,尚需进一步探讨。Aiming at solving calculation puzzle of natural water body volume,taking S Ideal edge-water-driven reservoir for example and the exact solution from Liaoyuntao＇s Method as constraint conditions,the article achieves an easy calculation method for natural water body volume of ideal edge-water-driven reservoir on the basis of water intrusion calculation formula,and with mainly calibration to System compressibility.It has attained good result in application to similar reservoir and also provided important reference for choosing suitable development mode.For high-permeability,thin-oil reservoir which has complete well network and been brought into complete development,which completely depends on edge water supplement energy and mainly bases on natural flow;as long as the total pressure drop and relative water intrusion can be confirmed,the natural water body volume will be estimated when there is obvious oil layer pressure drop after several years＇ development.It needs deeper research to find whether the method can be more widely used.
