摘要:
针对疏松砂岩油藏开发过程中油井出砂影响产能的问题,提出了压裂充填防砂完井技术,实现在控制地层出砂的同时提高油井产量。应用数值模拟方法,以增产倍数作为目标函数,对不同储层、流体及井距等条件下的压裂充填防砂增产效果进行了计算分析,计算结果表明:压裂充填防砂后油井增产的倍数在1.3~2.6倍之间,其中增产效果对渗透率级差、低/高渗储层厚度比、原油黏度的变化不敏感,与储层渗透率、厚度及井距近似呈线性负相关。因此对于渗透率相对较低、厚度较薄及井距较小的油井,应用压裂充填防砂技术后,增产效果会更加明显。在渤海S油田的现场应用实例表明,压裂充填防砂技术有效提高了单井产能,较非压裂充填防砂井产能平均提高2.6倍左右,该技术对疏松砂岩油藏的有效开发及长期稳产具有重要的意义。
Abstract:
Considering the problem that sand production of oil wells affects productivity during the production of unconsolidated sandstone reservoirs,a fracturing-filling sand control completion technology was proposed to increase oil well production while controlling formation sand production. Using the numerical simulation method,with stimulation multiple as the objective function,the effects of productivity improvement under the different reservoir,fluid,and well spacing conditions were calculated and analyzed.The calculation results show that the stimulation multiple of oil wells after fracturing packing and sand control is between 1.3 and 2.6 times. The stimulation effect is not sensitive to changes in permeability difference,low and high permeability reservoir thickness ratios,and crude oil viscosity,but it is approximately linearly negative correlated with reservoir permeability,thickness,and well spacing. Therefore,for oil wells with relatively lower permeability,thinner thickness,and smaller well spacing,the stimulation effect will be more obvious after the application of fracturing packing sand control technology.Field application examples in the Bohai S Oilfield show that the fracturing packing sand control technology effectively increases the productivity of a single well,which is about 2.6 times higher than that of non-fracturing pack sand control wells. This technology is of great significance to the effective development and long-term stable production of unconsolidated sandstone reservoirs.
