The invention has the beneficial effects that the device for automatically analyzing and optimizing the oil well and increasing yield, provided by the invention, monitors the flowing bottom-hole pressure in real time, coordinates with pulse conduction for stimulating the surrounding of the bottom hole, can boost free air to enter oil by promoting the energy of a reservoir stratum, can achieve the purpose of uniformly mixing air and oil, can further reduce the liquid viscidity, can increase the liquidity of oil in water and can increase yield. Meanwhile, on the pipeline, the raw oil temperature is increased through a heat tracing device, the liquidity is enhanced, and the extraction efficiency is prevented from being influenced by pipeline scaling.

Description

technical field [0001] The invention relates to the technical field of oil exploitation and transportation, in particular to an automatic oil well analysis and optimization stimulation device. Background technique [0002] In oil extraction operations, because a part of the oil will stick to the pipeline, the water content in the oil will increase over time, which will cause a large number of air bubbles in the pumped liquid, hindering the flow of the liquid, causing equipment failure or clogged. Usually, by pressurizing the pumped liquid, the gas enters the solution, thereby improving the fluidity of the oil on the water, reducing the viscosity, thereby reducing the water content and increasing the flow rate. However, as well conditions and the composition of the pumped fluid mixture change, so does the optimal bottomhole flowing pressure; currently, only data is provided by downhole sensors. Manual adjustment of well parameters is required, causing delays in optimizing o...

Problems solved by technology

However, as well conditions and the composition of the pumped fluid mixture change, so does the optimal bottomhole flowing pressure; currently, only data is provided by downhole sensors

Requires manual adjustment of well parameters, resulting in delays in optimizing operating conditions

Downhole sensors may be bad, or malfunctioning, but are difficult and expensive to install or repair

Even if there are downhole sensors, other testing equipment is needed to measure, and it can only be measured intermittently; and the current oilfield pipeline transportation adopts a three-pipe process, which has low efficiency, poor waterproof performance, and pipelines are prone to fouling
