RESERVOIR CONNECTION OF A FLUVIAL MULTI-LAYERED SANDSTONE RESERVOIR OF THE BOHAI P OILFIELD
-
摘要:
为解决渤海P油田注水开发过程中逐渐暴露出的注水井吸水不均衡、注入水单层突进、储量动用不均衡等问题，以搞清剩余油分布及指导油田井网优化。通过对压力变化、水淹状况、生产干扰情况及储层沉积、储层展布等方面的分析，对河流相多层砂岩油藏储层连通性及控制因素进行了研究。认为不同沉积类型条件下，馆陶组辨状河沉积储层连通性优于明化镇组曲流河沉积，相同沉积类型中，沉积规模广、砂体呈垂向叠加，且夹层不发育的储层连通性好。可见，研究区储层连通性主要受沉积类型、沉积规模、砂体叠加模式及夹层展布的影响。
Abstract:In the process of water injection in the Bohai P Oilfield, many problems appeared, such as the imbalanced water absorption of injection wells, injection water breakthrough, uneven utilization of reserves, and understanding of the distribution of residual oil. In this paper, reservoir connection and its controlling factors for fluvial multilayer sandstone reservoirs were studied through analysis of the data concerning pressure, water flooding, sedimentology and reservoir distribution. The results suggest that for different types of sediments, the reservoir connection of the Guantao Formation is better than that of the Minghua Formation in general. For the sediments of same type, however, the connection is better in the reservoirs with wide distribution, verticallysuperimpositionand lacking of intercalations.
