摘要：

HJ油田高轮次蒸汽吞吐后储层物性变化明显而又难确定,对后续开发措施的设计与实施造成了严重阻碍。针对这一问题,以J151和J117两口井为研究对象,在计算油层冲刷倍数的基础上对一维物理模拟实验参数进行设计,研究了蒸汽吞吐开发过程中储层孔隙度、渗透率以及润湿性的变化规律。结果表明,高温蒸汽对地层的长期冲刷可导致储层的物性参数发生变化,各小层蒸汽波及范围内的孔隙度和渗透率随吞吐轮次的增加而增大,储层岩石的亲油性逐渐减弱,亲水性逐渐加强。结合实验研究结果,建立了油层冲刷倍数与储层孔隙度增长率之间的关系式,以及油层冲刷倍数与渗透率增长率之间的关系图版。运用以上关系式和图版可以预测储层在蒸汽吞吐开发过程中不同阶段的孔渗参数,关系式和图版也可推广至其他同类稠油油藏。

Abstract:

After multi-cycle steam stimulation in HJ Oilfield, the changes of reservoir physical properties are obvious and difficult to determine, which brings serious obstacles to the design and implementation of subsequent development measures. In order to solve this problem, the relationships among porosity, permeability, wettability and steam stimulation cycles are conducted by using one-dimensional physical simulation experimental setup after the design of sweep multiples based on two wells, Well-J151 and Well-J117 in HJ Oilfield. The results show that the physical property parameters of reservoir will change under the long-term sweep of high temperature steam. In the scope of steam sweep, both porosity and permeability all increase with the increase of the steam stimulation cycles. With the increase of steam stimulation cycles, the lipophilicity of reservoir rocks gradually weakened and the hydrophilicity gradually strengthened. Based on the experimental results, the relationship between sweep multiples and porosity growth rate, as well as the chart of the relationship between oil layer sweep multiples and permeability growth rate are established. The parameters of the porosity and permeability of reservoirs in different stages of steam stimulation development can be predicted by the above relationship and chart, and the relationship and chart can be also extended to other similar heavy oil reservoirs.

Key words: heavy oil, steam stimulation, sweep multiples, reservoir property, thermal recovery
