影响低渗油藏储层驱替压力系统建立的最主要因素是启动压力梯度。所以,在低渗透油藏的开发中,应按照一定标准适当缩小注采井距来提高驱替压力梯度,采取整体压裂措施减小启动压力梯度。此外,采用数值模拟的方法对油藏开发方案进行优化,优化项目主要包括注水和压裂时机的选择。这对低渗透油藏的高效开发有重要的意义。
The most important factor that affects the establishment of reservoir displacement pressure system in low-permeability reservoirs is the initiation of pressure gradient. Therefore, in the development of low-permeability reservoirs, the well spacing should be narrowed down according to certain criteria to improve the displacement pressure gradient, and the overall fracturing measures should be taken to reduce the starting pressure gradient. In addition, the numerical simulation method is used to optimize the reservoir development plan. The optimization project mainly includes the selection of the timing of water injection and fracturing. This is of great significance for the efficient development of low-permeability reservoirs.
