萨北开发区井震结合断层区精细挖潜研究
|
摘要
萨北开发区纯油区西部断层较为发育,受其影响,局部区域井网不规则、注采关系不完善、剩余潜力较大。2010年以来,完成了该区块高密度三维地震数据采集和开发地震构造解释,重新精细刻画断层分布、注采关系及潜力分布,并以此为基础,开展了井震结合断层区精细挖潜研究。根据不同区域剩余油分布特点,优选出复杂断块区注采系统调整、大断层附近整体部署高效直井、断层间窄条带区域大斜度井挖潜及常规措施调整等4种挖潜模式,取得了较好的开发效果,为断层区的精细挖潜提供了重要的技术支撑。
Due to the developed fault in the West of Sabei Development Area, local well pattern is irregular, relationship between injection and production is imperfect, and the surplus potential is great. Since 2010, data acquisition about high density 3D seismic and seismic structural interpretation have been completed, the fault distribution, variation of injection production relationship and potential distribution were described. Based on this, a research of fine research on well seismic combined with fault zone is carried out. According to the distribution characteristics of residual oil in different regions, the system adjustment on injection and production system in complex fault zone, arrangement of the efficient vertical wells near the large fault, productionpotential digging of high angle wells in the fault between narrow strip and implemented conventional measures are selected. After the implementation, good development effects have been achieved, and it provides important technical support for fine potential digging in fault zone.
