综合处理工艺是基于对非均质开采层的渗滤场,通过注水井和采油井进行化学剂处理,以便同时提高油藏的波及面积和驱油程度。波及面积的提高是靠控制驱替剂在非均质地层中的方向性作用,使驱替剂渗入难以驱替的含油层带,而在酸化之前向地层中注入定量的化学剂,以阻止酸法渗入高渗透层。该综合处理工艺在亚柯夫油田间П—1+2层进行了矿场试验。结果表明:难以采出的原油储量来出率提高10%~12%;增产100t原油需化学剂1t。本工艺技术获乌克兰专利。
The integrated treatment process is based on a percolation site for heterogeneous production layers that is treated chemically with water injection wells and production wells to simultaneously increase reservoir area and flooding. The increase in sweep area is controlled by the directivity of the displacing agent in the heterogeneous formation, causing the displacing agent to penetrate into the hard-to-displace oil-bearing zones and injecting quantitative chemicals into the formation prior to acidification to prevent acid Law into the high permeability layer. The integrated process conducted field tests on the П-1 + 2 floor of the Yakov field. The results show that crude oil reserves, which are difficult to be extracted, increase the yield by 10% ~ 12% and increase the production of 100t crude oil by 1t. The process technology by the Ukrainian patent.
