摘要/Abstract

摘要： 针对海上疏松砂岩注水井周围经长期冲刷易发育大孔道的问题，通过引入Barree-Conway模型对大孔道内高速非达西渗流进行描述，采用迭代方法对高速非达西渗流导致的强非线性问题进行处理，并结合线源、Laplace变换及数值离散方法构建考虑高速非达西渗流的发育多条大孔道的注水直井试井解释模型，并对典型压力动态曲线及相关参数的影响展开分析。研究结果表明：①考虑高速非达西渗流的发育多条大孔道的注水直井不稳定试井半解析模型可以有效处理多条大孔道发育及大孔道内的高速非达西渗流，且计算结果更加可靠。②发育多条大孔道的注水直井的典型压力曲线可划分为井储、过渡段、双线性流、线性流、大孔道干扰及径向流等6个流动阶段。考虑高速非达西渗流后，早期压力及压力导数曲线均明显向上移动，近井大孔道内导流能力出现明显下降。随着大孔道数量的增多，压力及压力导数曲线明显下移，同时大孔道内高速非达西渗流的影响程度减小。③将此模型应用于渤海油田注水井参数解释，可实现大孔道的定量表征。

Abstract: To focus on the issue of high permeability flow channels developed upon long-term strong water erosion in offshore unconsolidated sandstone，the Barree-Conway model was employed to describe the highvelocity non-Darcy flow within flow channels. An iterative method was adopted for the strong nonlinearity caused by high-velocity non-Darcy flow. Then a pressure transient model of vertical injection well with multi flow channels considering high-velocity non-Darcy flow was obtained through line source，Laplace transformation and numerical discretization methods，and the typical pressure dynamic curves and related parameters were analyzed.The results show that：（1）The semi-analytical model for unstable well-testing in vertical injection well with multi flow channels considering high-velocity non-Darcy flow can effectively address both the development of multi high permeability flow channels and high-velocity non-Darcy flow within these channels，and the calculation results are more reliable.（2）The typical pressure curves of vertical injection well with multi flow channels can be divided into six flow stages：wellbore storage，transition flow，bilinear flow，linear flow，flow channel interference，and radial flow. When high-velocity non-Darcy flow is considered，both the early stage pressure and pressure derivative curves move up significantly，and the flow conductivity capacity of the multi flow channels near wellbore shift down significantly. As the numbers of flow channels increase，the pressure and pressure derivative curves decrease significantly，while the influence of high-velocity non-Darcy flow within the flow channels diminishes.（3）The model was successfully applied to the parameters interpretation of an injection well in Bohai Oilfield，then the quantitative characterization of flow channels can be achieved.

Key words: vertical injection well, large pore channel, high-velocity non-Darcy flow, line source, Laplace transformation, numerical discretization methods, well testing interpretation model, iterative method
