摘要
河西务油田呈北东、南西向展布,由十余个断块组成,是典型的多断块复杂油气藏。该油藏具有埋藏深、孔隙度小、渗透率低、储量丰度低、地层压力高、油气比高的特点,为典型的高压低渗透油藏。为解决油田各断块低效生产的开发现状,提高断块开发水平,本文提出的治理方案以油田中部复杂小断块为切入点,完善注采井网,恢复地层压力,提高水驱控制程度;重新认识油藏类型,开展开发技术政策研究;结合测井复查和动态信息,开展层间挖潜,提高油层动用程度。
The Hexiwu Oilfield is distributed north-east and south-west,consisting of over ten fault blocks,which is a typical complex oil and gas reservoir with multiple fault blocks.The reservoir has the characteristics of deep burial,low porosity,low permeability,low reservoir richness,high formation pressure,and high oilgas ratio,which is a typical high-pressure low-permeability reservoir.In order to solve the low-efficiency production situation of the oilfield's various fault blocks and improve the fault block development level,the scheme takes the complex small fault block in the middle of the oilfield as the starting point,improves the injection and production well network,restores the formation pressure,and improves the water drive control degree;re-recognizes the reservoir type and conducts development technology policy research;at the same time,combines the logging re-verification and dynamic information to carry out inter-layer exploitation,and improves the utilization degree of the oil layer.
