吴起油田X255C6油藏滚动扩边提高单井产量技术研究

Wuqi oilfield Xin255 region Chang 6 low permeability reservoir research to improve the yield of single well early technology

本文主要以吴起油田五谷城X255C6油藏为研究对象,针对C6低渗透油藏低产井的储层特性和不同开发阶段,以油藏为单元,结合沉积微相研究,在实践的基础上,逐步形成了以注水开发为主,细分建产单元、强化随钻分析、精细测井解释、优化储层改造等与之相适应的提高单井产量的方法及技术,并根据油田开发实际,不断调整完善,使低品位油藏单井产能得以充分发挥,最终提高了采收率和效益,也为长庆油田同类油藏及0.3 m D储层有效开发奠定了技术储备。

Aiming at the Xin255 oilfield＇s Chang 6 reservoir quality of low permeability layer and low yield in different development phase, according to the Chang 6 low yield wells in low permeability reservoir and reservoir characteristics of different stages of development, the reservoir as a unit, combined with sedimentary microfacies study.On the basis of practice,gradually formed the waterflood development, construction of production units, strengthening subdivision drilling analysis, fine logging interpretation, reservoir reconstruction and optimization of the corresponding increase single well initial production methods and technology.And according to the actual development of oilfield, continuously improving the low-grade reservoirs single well early productivity into full play, not only improve the oilfield development level, the ultimate recovery and benefit,but slso provides technical reserves for the similar reservoir in Changqing oilfield and 0.3 m D reservoir development.
