Abstract

The invention relates to an oil well exploiting device, in particular to a water-adding viscosity-reducing device. The technical scheme is that the water-adding viscosity-reducing device is mainly composed of a well filed, an oil outlet pipe, a metering station and a water-adding pipe. The well filed is respectively connected with the oil outlet pipe and the water-adding pipe, the oil outlet pipe is connected with the metering station, the metering station comprises a metering separator and a heating furnace, the heating furnace is fixed on the oil outlet pipe, and the oil outlet pipe is connected with the metering separator through the heating furnace. The water-adding viscosity-reducing device has the advantages that the exploiting of high-viscosity crude oil is achieved, the water-adding viscosity-reducing device is put into production easily and is convenient to manage, production is stopped easily and is safe, the well filed and a main line are not provided with the heating furnace, fuel is saved, and back pressure is reduced effectively.

Description

technical field [0001] The invention relates to an oil well exploitation instrument, in particular to a water-mixed viscosity reducing device. Background technique [0002] In oilfield exploitation, especially in the exploitation of heavy oil wells, due to the high viscosity of crude oil, the oilfield cannot be normally exploited. At present, chemical additives are commonly used in oilfield exploitation, which increases the cost of oilfield exploitation. Contents of the invention [0003] The object of the present invention is to provide a water-mixed viscosity reducing device for the above-mentioned defects in the prior art, which solves the problem of high-viscosity crude oil exploitation. [0004] The technical solution is: it is mainly composed of a well site, an oil delivery pipeline, a metering station, and a water mixing pipeline. The well site is respectively connected to the oil delivery pipeline and the water mixing pipeline. A metering separator and a heating f...
