摘要
鲁克沁油田西区油层埋藏深,流体粘度高,储层物性相对较差,但储量较为丰厚。由于储层流体流动性差,依靠天然能量开发或者配套井筒掺稀油降粘有杆泵举升开发,单井产量低。室内实验证明,进行天然气吞吐可大幅度降低原油粘度,提高单井产量,并开展了注天然气吞吐矿场试验,取得了较好的增产效果。
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.
