【摘要】 以榆树林东16井区升371和东160两相邻断块为例,根据两断块井网形式一致,但井排方向和裂缝主方向略有不同、砂体特征差异大的特点,在分析两断块油井不同的生产动态基础上,对该区井网的适应性进行了评价。并根据两断块的不同地质特点以及该区加密试验区的动态生产情况,以低渗透油藏的合理排距为依据,提出了井网加密和注水调整方式,符合该区的实际特点,利用数值模拟技术进行了研究,结果表明该加密调整方式可以取得较好的效果。更多还原

【Abstract】 On the basis of analyzing the different production performance,well pattern adaptation for Sheng 371 block and Dong 160 block in Dong16 borefield was evaluated according to their identical well pattern but different relation of well line direction and fracture direction and sand character.Adjusting methods of well pattern and injecting were proposed according to the different geological characters,production performance of well infilled test area in the two different fault blocks.Adjusting methods of well pattern and injecting were studied with numerical simulation technology and the result showed us it could bring a satisfying outcome.更多还原
