摘要
八面河未动用储量主要为沙四段滩坝砂储量,其主要特点是层薄、渗透率低、油稠,难动用。在近3年技术攻关和现场试验摸索中,积极采取老井复查与新井评价相结合的方式,重点针对规模较大、适宜注水的区块开展储层再认识,落实储层、储量,借鉴低渗透油藏开发思路,实施先期注水,优化多段塞复合压裂工艺,提高单井产能,改善开发效益,努力实现难动用滩坝砂储量经济有效开发。
The undeveloped reserves in Bamianhe are mainly beach bar sand of No.4 section of Shahejie formation. Its main characteristics are thin layer, low permeability, heavy oil and difficulty of development. In the technical research and field test of the past three years, oil mine review and new mine evaluation were combined, the reservoirs in the large scale sections suitable for water injection are recognized, the reservoirs and reserves are committed. Referring to the development thought of low permeability oil reservoir, early water injection was carried out, multiple section compound fracturing technology was optimized, individual well deliverability was improved, and the development benefit was improved, thus the hard-to-produce beach bar sand reserves economy can be developed well.
