低渗储层堵塞机理研究

Study on plugging mechanism of low permeability reservoir

目前低渗储层在油田开发中占有重要的地位,由于低渗储层孔喉小、储层物性相对较差,在开发过程中易产生孔喉堵塞问题。本文对低渗储层的堵塞机理进行了分析。

Low permeability reservoirs play an important role in the development of oilfields. Due to the low porosity and lowphysical properties of reservoirs,the pore-throat clogging problem is likely to occur in the development process. In this paper,theblocking mechanism of low permeability reservoir is analyzed.
