电杆越泵加热技术是把整筒抽油系改制成空心环流抽油泵，把空心抽油杆直接穿越过泵下到泵下一定深度，电缆下入空心杆中，利用集肤效应原理，同时对泵上、泵下及泵体内的原油加热，降低原油粘度及原油入泵阻力，提高油井产量。该技术解决了特稠油、超稠油入泵难的难题，是开采深层特稠油、超稠油这类无法动用油藏的一种切实可行的采油工艺方法。 Pole more pump heating technology is the entire cylinder pumping system is transformed into a hollow circulation pump, the hollow sucker rod directly through the pump to a certain depth under the pump, the cable into the hollow rod, the use of skin effect principle, at the same time On the pump, the pump and pump the body of crude oil heating, reduce the viscosity of crude oil and crude oil into the pump resistance, improve oil production. The technology solves the difficult problem of injecting extra-heavy oil and ultra-heavy oil, and is a feasible oil recovery method for deep-seated extra-heavy oil and ultra-heavy oil which can not be used.
