靖安油田杨66延9油藏早期开发技术政策研究

Jing'an oilfield 66 Yang Yan 9 oil reservoir early development of technology policy research

杨66延9油藏在开发过程中面临着能量保持水平低、油井见效程度偏弱、油藏开发强度偏小,需进一步提高油藏开发水平的问题。本文在分析总结油藏开发过程中的动态变化特征及规律的基础上,重点通过油藏工程方法计算,同时借鉴同类油藏开发特点及变化规律,分析制定更符合油藏开发实际的压力保持水平、注水强度、注采比及采液强度等技术指标,通过不断优化注水技术政策,促使油藏进一步见效,提高油藏开发水平。

66 Yang Yan 9 oil reservoir facing low energy to maintain the level, the degree of effective weak wells, reservoir development intensity is too small, need to further improve the level of reservoir development issues in the development process. Based on the analysis summarized reservoir development process dynamic characteristics and rules on focusing through reservoir engineering calculations, drawing on similar reservoir development characteristics and changing law, the analysis to develop more in line with the pressure to maintain the lev- el of actual reservoir development, water injection strength, injection-production ratio and liquid production strength technical indicators through continuous optimization of water injection technology policies to promote effective reservoir further improve reservoir development level.
