Abstract: Lukqin Western oil reservoir is buried deep,fluid viscosity is high,reservoir property is relatively poor,but rich in reserve capacity.Due to the poor reservoir fluid flow,the development is relied on natural energy or the supporting shaftdoped thin rod pump lift to reduce the oil viscosity,as a result,single well production is low.The laboratory test proved to be a significant reduction in crude oil viscosity with the application of natural gas stimulation,and it can in-crease production per well.The natural gas injection stimulation has been carried out in site and has achieved better yield increasing effect.
