Description

technical field [0001] The invention belongs to the technical field of oil field remote monitoring, and in particular relates to a mobile oil field water plugging and profile control remote monitoring system based on Web technology. Background technique [0002] Water plugging and profile control technology has always been an effective means for oilfields to improve water flooding development effects and achieve stable production of oil reservoirs. Water plugging is generally aimed at oil well construction, which is to control the water-oil ratio or control water production. Its purpose is to remedy the poor cementing quality of the oil well, reduce the permeability of the water-flooded layer, and increase the recovery of the oil layer. At present, the commonly used water plugging method in Changqing Oilfield is chemical method, which uses the chemical action of plugging agent to block the water outlet layer. Profile control generally refers to the construction of water inj...
