摘要:
鸭儿峡M油藏具有断层发育、饱和压力低、边水极弱等特征，为了准确把握该油藏最佳注水时机，必须实时准确掌握地层压力水平。基于物质平衡原理，考虑岩石和流体的高压物性随地层压力变化，利用岩石孔隙体积和油水体积的动态变化关系，得到能够实时跟踪弹性开采阶段和注水开发阶段的地层压力计算公式，在实验准确获取岩石和流体高压物性参数后，实现地层压力计算。结果表明，采用物质平衡法计算的M油藏平均地层压力为405 MPa，与试井解释结果仅相差05 MPa；岩石孔隙体积缩小量与流体体积缩小量误差为20%，物性参数取值可靠。物质平衡法为应用生产动态资料实时准确评价封闭或弱、边底水油藏的地层压力提供了新的思路。
Abstract:
 The M reservoir in Yaerxia oilfield has the characteristics of fault development, low saturation pressure and extremely weak edge water. For clarifying the optimal water flooding time of the reservoir, it is necessary to understand the formation pressure accurately in real time. Considering that high pressure physical properties of rock and fluids change with the formation pressure, and the dynamic changes of reservoir pore volume and oilwater volume, the calculation formula of formation pressure was obtained according to the principle of material balance, and it can calculate the formation pressure after acquiring the highpressure physical properties of rock and fluids, so as to keep realtime track on the formation pressure in the elastic production and waterflooding stages. The results show that the average formation pressure of M reservoir obtained by using the material balance method is 405 MPa, only 05 MPa different from the results of well testing. In addition, the error of reservoir pore volume compressibility and fluid volume compressibility is 2%, suggesting that the value of physical parameters is reliable. The material balance method provides a new idea for the application of production performance data to evaluate the formation pressure of closed or weak edge/bottom water reservoirs in real time manner.
