含油饱和度分布状况、压力分布状况、水驱油方向等,可预测未来油田生产状况,而单井单层的产、注量受这些场分布状况的影响,数值模拟中单井产、注量的时空拟合状况也能反映出所拟合的这些场的准确程度。数值模拟技术的重点由获得高精度的含油饱和度场、压力场转化为采用合理、科学的方法,提高单井、单层产液、产油、注水等数据拟合精度。但目前的单井拟合方法较为简单,没有系统的考虑油藏状况,因此拟合精度低。研究了数值模拟原理和油藏实际生产之间的关系,并提出了“井区拟合+含油饱和度场+压力场+沉积相带图”进行综合分析的拟合思路。
Oil saturation distribution, pressure distribution and water flooding direction can predict the production status of future oilfields. However, the single-well single-layer production and injection are affected by the distribution of these fields. In the numerical simulation, single well production and fluence The spatiotemporal fit also reflects the accuracy of these fields that are fitted. The focus of numerical simulation technology is to obtain high-precision oil saturation and pressure fields by using reasonable and scientific methods to improve the data fitting accuracy of single-well, single-layer liquid production, oil production and water injection. However, the current single-well fitting method is relatively simple and does not systematically consider reservoir conditions, so the fitting accuracy is low. The relationship between the numerical simulation principle and the actual production of the reservoir is studied, and a fitting idea of “well area fitting + oil saturation field + pressure field + sedimentary facies band diagram” is proposed.
