摘要:
CB油田是受构造控制,局部受岩性影响的油气富集程度较高的复杂断块砂岩油藏。油田自上而下探明5套含油层系,有6个地质特征。针对CB油田开发初期所暴露出的问题,及时改变了开发策略,改变早期制定的逐层上返的开发方式,加大了新技术应用,走细分层开发之路。在深化地质研究与细分层开发技术政策研究的基础上,通过利用水平井与常规井组合开采以及有序细分层开发确保了油田采收率不断提高。从CB油田提高采收率实践中认识到技术的进步,特别是开发思路的转变,观念的转变为采收率的提高打下了基础。
Abstract:
CB Oilfield belongs to the rich complex small fault block sand stone reservoir predominated by the structure and influenced by lithology locally. Aiming at the main problems and inconsistency in initial oilfield development stage,exploitation strategy and development mode of developing upward in turn were changed. New technology was widely used, such as subdivision of strata. On the basis of fine reservoir description and technology policy research of subdivision of strata, the combination development method of horizontal and general wells and calculated subdivision of strata whose purpose was a long- term stable production were carried out, which insures the enhancement of oil recovery. Through the practice of enhancing oil recovery in CB Oilfield, it was realized that the technology progress and the translation of exploitation consideration are important bases of enhancing recovery.
