雷11块莲花油层属于复杂断块低阻底水稀油油藏,纵向上存在多套储层,由于储层非均质性严重以及各套储层油藏类型不同,导致油井大套井段合采后储量动用不均,影响区块开发效果,为此2011年提出分层开发的理念,即细分开发单元,针对不同类储层制定相适宜的开发方式,解决纵向上储量动用不均问题,但实施分层开发之间,有必要对其可行性研究。 Eleven Lianhua reservoir belongs to the complex fault block low resistance bottom water dilute reservoir, there are several sets of reservoirs in the longitudinal direction. Due to the serious reservoir heterogeneity and the different types of reservoirs, Due to the unequal use of reserves after the joint production, the effect of block development is affected. Therefore, the concept of layer development was proposed in 2011, that is, the development unit was subdivided, appropriate development methods were developed for different types of reservoirs, and uneven utilization of reserves Problems, but the implementation of stratified development, it is necessary for its feasibility study.
