低渗敏感性油藏有效开发技术探索

The Investigation of Developing Low-sensitivity Oil Reservoir

随着油田开发的不断深入,提升"低产低效单元"采收率已逐步成为产量接替的重点,低渗透敏感性油藏开发成为必然趋势.为实现南坡油田甲A区块低渗敏感性油藏的有效开发,围绕该区块储层特点,开展评价性试验,在对油藏储层泥质含量高、敏感性强等开发难点研究基础上,针对性地提出开发工艺配套措施,并全程实施油藏保护.

With the increasing development of oil wells, the enhancing of low-production-low-efficiency recovery unit has become the production transfer focus, and the low-permeability reservoir development is the current trend. In order to effectively develop low-permeability oil in the A section of Nanpo oil well, this paper, with the reservoir layer feather as the focus, carries out an evaluative experiment, and on the basis of the investigation of high mud content in the oil reservoir, high-sensitivity-caused difficulty in developing, it proposes a systematic developing technology, and the measures of oil reservoir protection.
