针对渤海埕北稠油油田主力产层油井严重水淹、剩余油分布复杂、潜力储量的非常规稠油难以动用及海上平台空间有限等主要矛盾，以精细油藏描述为基础，一方面放大老井生产压差进行大泵提液，提升现有设备下的老井产量，另一方面，在油藏边部井网不完善区域部署调整井；在论证非常规稠油冷采产能基础上，确定以大压差开采馆陶组稠油，以提高潜力储量动用程度。这些方法的研究与应用使埕北油田成功实现了产量接替，同时也为海上今后进入开发后期的油田提供借鉴。

Measures have been taken to handle the issues of serious flooding in wells of main production layers, complex distribution of residual oil, dififcult to explore the potential unconventional oil reserves and limit space of offshore platform in Bohai Chengbei oil ifeld. Based on ifne reservoir description, for one thing, the production pressure differential of old well was enlarged to extract lfuid by large pump to promote the producing potential of old well with existing equipment;for another thing, adjusting wells were arranged in reservoir edge where well network is imperfect region; High pressure differential was adopted to develop heavy oil in Group Guantao to improve the producing degree of potential reserve on the basis of demonstrating production capacity of unconventional cold heavy oil. The research and application of these methods successfully realize the production replacement in Chengbei oil ifeld;meanwhile provide reference for offshore Oilifelds which is entering into the late stage of development.
