【摘要】 本文以大庆油田三次加密矿场实践为依据，通过对试验效果的系统评价研究，提出了对三次加密井工艺技术的要求；分析了低效井的原因，研究了降低低效井比例的有效方法，并在杏一～三区矿场试验中得到了验证；通过对加密井单井经济技术界限研究，搞清了三次加密调整的投资成本构成，制定了三次加密调整井增加可采储量、厚度和产量界限；指出了三次加密潜力对象及其分布特征；提出了以精细地质研究为基础搞清薄差储层沉积特征及空间展布、以剩余油综合描述为手段定量描述各沉积单元的剩余油分布特征、以经济有效开发为目的的三次加密调整方法、原则和程序；制定了三次加密井初含水与可采储量测算方法；研究确立了扩大三次加密调整规模的途径。 项目研究成果适用于多油层砂岩油田高含水期加密调整，丰富了和发展了多油层砂岩油田多次调整的实践与理论。更多还原

【Abstract】 This paper was put forward to the demand for production techniques of third infilling by the systematic analysis of the test results based on the data of third infilling pilot in daqing oilfield.Through the causes of low producing well were analysised.the effective method of decreasing low producing well were researched.These methods were verificated in the infilling pilot area of Xing 1-3. The investment cost composition was made clear by studying the technical and economic limit of infilling well. On the bases, the recoverable reserve, thickness and production limit were determined, the potential and distribution characteristic were pointed out. This paper was put forward to the method, principle and procedure of third infilling in order to the economic effective development based on fine reservoir description and remaining oil research. Meanwhile, the calculation methods of initial water cut and recoverable reserve of third infilling well were studed, and the approach of third infilling scale was developed.This research result can be applied in the infilling adjustment in multi-layered and heterogeneous sandstone reservoir at late period of high water cut stage, so it developed the the practice and theory of infilling adjustment in multi-layered and heterogeneous sandstone reservoir.更多还原
