摘要:
针对陈家庄油田陈25块原油粘度较大、水驱效率低的特点,室内实验优选了一种降黏体系。通过仪器测试和模拟油藏条件,开展了流度比和岩心水驱实验。实验结果表明,降黏体系浓度600 mg/L,水溶液黏度提高8.2倍; 降黏体系浓度400 mg/L,地层条件下原油降黏率达到53.6%。体系浓度600 mg/L,水驱后注入降黏体系0.5PV,可提高驱油效率18.7%。注入降黏体系后,驱替压力明显上升。注入时机越早,提高水驱效果越明显。
Abstract:
There are higher viscosity oil and lower waterflooding recovery in block C25 of Chengjiazhuang oilfield.Aiming at these problems,a kind of water-based viscosity reducer was screened in lab.According to the real reservoir condition,a series of mobility ratio measurements and core flooding experiments were carried out. Experimental results show that adding the viscosity reducer solution with 400 mg/L concentration,the oil viscosity was reduced by 53.6% under condition of reservoir; the viscosity of the viscosity reducer solution with 600mg/L concentration is 8.2 times that of water,and the viscosity reducer solution of 0.5 pore volume(PV)after waterflooding was injected, a incremental oil recovery reached to 18.7%; after injecting the viscosity reducer solution,the displacement pressure was obviously increased; the earlier the viscosity reducer flood is,the higher the incremental oil recovery is.
