摘要:
在储层改造基础上进行蒸汽吞吐是低渗透稠油油藏的可行开发方式,探究开采过程中不同条件对储层原油流动能力的影响,并定量确定储量动用范围的变化规律,可为此类油藏的有效开发提供科学依据.分析基于蒸汽吞吐过程中的温度剖面变化和储量动用过程,定量描述了储层中原油流动能力的变化规律,建立了反映低渗透稠油油藏热采储层中渗流特点的数学模型,计算得到低渗透稠油油藏注热开采后压力分布及产量的分段式变化规律;提出通过原油流动及储量动用的极限动用半径、易流动半径和经济有效动用半径,来刻画低渗稠油储层注热开采后储量动用特点;通过研究不同动用半径的非线性变化规律,得到不同开采条件下的储量有效动用范围,为低渗透稠油油藏蒸汽吞吐热采开发合理井网设计提供关键参数.
Abstract:
Steam huff-n-puff along with reservoir stimulation techniques have been confirmed as a feasible development method for low permeability heavy oil reservoirs. Both the study upon the impacts of different production conditions on the flow capacity of reservoir crude oil, and the quantitative determination of the variation law of reserve utilization range, can provide the profound basis for the effective development of such reservoirs. In this paper, through the analysis of the changes of temperature profile in the process of steam huff-n-puff, the changes of crude oil flow capacity in reservoirs are described quantitatively. Also, a mathematical model that reflects the seepage characteristics during thermal recovery in low-permeability heavy oil reservoir is established, and as a result, the pressure distribution and production characteristics of each stage after heat injection can be obtained. For describing the production characteristics after heat injection in low-permeability heavy oil reservoirs, this paper defines some indicators for use including the ultimate utilization radius, easy-to-flow radius and effective economic-utilization radius. The range of recovered reserve can be also obtained under different production conditions by knowing the nonlinear change of utilization radius at different time. In all, the outcomes of this work can be used to help design the optimal well pattern for the low-permeability heavy oil reservoirs development by steam huff-n-puff.
