摘要
深部液流转向技术是目前常用的稳油控水技术之一。针对渤海油田窄河道型油藏,常规深部液流转向体系注入困难的问题,开发一套适用于该类油藏的深部液流转向体系。通过室内实验,确定体系包括凝胶体系BHTP-1和颗粒体系BHTP-2,体系段塞为弱凝胶+中等凝胶+BHTP-2+强凝胶的组合方式,增油效果较好,驱油效率提高15%以上。该体系在渤中25-1南油田成功应用7井组,已累计增油2.4×104m3,措施效果明显。
Profile control technique is one of the commonly used techniques for stabilizing oil and water control. It is problem that arrow channel type reservoir which is difficult to be injected with conventional profile control agent. It is necessary to develop a suitable profile control agent. Through the research, the agent includes the gel BHTP-1 and the grain BHTP-2. It is the best that the agent is a combination of weak gel ＋ medium gel ＋BHTP-2＋ strong gel. The oil displacement efficiency is increased by more than 15 %. The successful application of the 7 well group in BZ25-1s oilfield, oil increasing 2.4×104m3.
