摘　　要：针对海拉尔盆地贝301断块注水开发过程中,注采系统不完善、储层动用程度低、含水上升较快等问题,运用油藏精细描述方法,进行精细构造解释、细分沉积微相、储层分类研究,优化开发调整技术,按照分区分类调整思路,考虑平面和纵向的开发矛盾,分别制定个性化调整对策。通过井网加密、注采系统调整、分层系调整、结合"调、压、补、堵"及水平井挖潜等措施,油田水驱控制程度提高12.8%,全区月产油由0.876 8×104t上升到1.384 3×104t,综合含水下降27.5%。初步形成了复杂断块油藏个性化调整技术,对同类油田的开发调整有重要的借鉴意义。In the development of water flooding Block Bei 301 in Hailar Basin,there exist the problems of imperfect injection-production system,low displacement efficiency and rapid raise of water cut.The fine interpretation of structure,fine classification of sedimentary microfacies,study on reservoir classification and optimization of development adjustment techniques are conducted by using reservoir fine description.Individual adjustment strategy is drawn up respectively based on the idea of adjustment by regions and by classifications,on considering vertical and lateral development contradiction.The waterflooding control degree is increased by 12.8%,monthly oil production in all the regions increases from 0.876 8 × 10 4 t to 1.384 3 × 10 4 t,gross water cut falls to 27.5% by drilling infill wells,adjusting injection-production system,the adjustment by strata series in the combination of the measures of ' adjusting,pressurizing,compensating perforation and shutting-off' and tagging reserve potential The individual adjusting techniques for complex fault reservoirs is initially formed,which is significant to the development adjustment of similar reservoirs.
