摘要/Abstract

摘要： 针对目前条带状油藏在压力传播方面研究的不足，从建立的简化条带状油藏模型出发，结合物质平衡原理，运用两参数连续模型和稳态逐次替换法，建立了定产和定压条件下的压力传播数学模型。不仅给出了条带状油藏的压力传播规律，同时也填补了低渗透油藏在一维不稳定渗流压力传播规律研究的空白，并对模型进行了相关应用及影响因素分析。认为：产量模型和定压模型的压力传播规律，时间均是传播距离的二次多项式，且在压力传播速度上，与产量呈正相关，与井底流压呈负相关。此外，还得出了获得最大产量所对应的最佳井底流压模型。

关键词: 压力传播规律, 模型, 条带状断块油藏, 物质平衡原理, 两参数连续模型

Abstract: There is a shortage of researches on pressure transmission in banded fault block reservoir. In view of this,this paper develops mathematical models by using steady state replacement method and material balance law based on two-parameter continuous model to study pressure transmission in low permeability reservoir under constant production rate and constant pressure. The research not only presents the law of pressure transmission of banded fault block reservoir,but also fills the blank in researches on one-dimensional unsteady seepage pressure transmission law in the low permeability reservoirs. The model was applied and the influencing factors were analyzed, and conclusions were drawn that in both constant yield model and the constant pressure model,time is quadratic polynomial of transmission distance. The pressure transmission velocity is positively correlated with the yield, but negatively correlated with the bottom hole flowing pressure. In addition, the model of optimum bottom hole flowing pressure corresponding to the maximum output was obtained.

Key words: pressure transmission law, the model, banded fault block reservoir, the material balance principle, two-parameter continuous model
