ENHANCE RECOVERY FACTOR BY IMPOSE ELECTRICITY ON OIL-LAYER

In order to enhance the development profit of low permeable oilfield,Improve the environment of production,We studied the technology production of imposing electric to oil-layers. This technology makes the direct and stable voltage electronic field acting on the parts of oil-layer, and constructs gradient of electric potential(physical field) in oil-layer. It acts on oil zone and its medium for a long time through chemical-electric way, for the electrodynamic purpose of eliminating the block of oil layers and for the electrochemical purpose to change the rocks physical property.In the end realize to enhance the recovery efficiency of oilfields. This paper demonstrates the feasibility and the theorise of stimulation by testing. It expounded the specific processes of testing in site,realizing ways and the testing effects and so on. From the point of testing, the process has matured, achieved connecting oil layers, and breaking down the blocks near the well, the technology is one of additional technology to stimulate low permeable oilfield to great profit.
