摘要:
特低渗透M油藏原始含水饱和度较高,弹性开采一段时间后,单井含水率呈现缓慢上升趋势。基于此生产特点,利用物质平衡原理,考虑岩石孔隙体积、流体体积以及高压物性参数随地层压力的变化,并结合油水相渗曲线,建立M油藏不同单井控制储量条件下的累计产水量增量与累计产油量、地层压力与累计产油量2套理论关系图版。文中以3口油井为例,实现了在不关井测压条件下,将实际生产动态数据与理论关系图版进行拟合,求取单井控制储量和单井地层压力。研究表明,该方法与压力恢复试井法的分析结果相近,且可靠性较高,在生产特征类似的特低渗透油藏中有一定的应用前景。
Abstract:
The original water saturation of the ultra-low permeability M reservoir is relatively high, and the water cut of the single well shows a slowly rising trend after a period of elastic production. Based on this production characteristics, using the principle of material balance, considering the change of rock pore volume, fluid volume and high-pressure physical parameters with formation pressure, combining with the relative permeability curves, two sets of theoretical relationship chart are established in M reservoir under different single well controlled reserves, which is cumulative oil production and the increment of cumulative water production chart and cumulative oil production and formation pressure chart. Taking three oil wells as an example, the single well controlled reserves and single well formation pressure were obtained by fitting the actual production dynamic data with the theoretical chart without shutting down the well. The research shows that this results are similar to those of the unstable well test analysis, which indicates that the method has high reliability and application prospect in the ultra-low permeability reservoir with similar production characteristics.
