【摘要】：随着油田开发的进行,吉林油田经过长时期开采,新探明的区块属于低渗透油油藏的较多,这些井日产液量只有几吨,如果按照常规开采方式,很难做到经济开采。根据国外有关资料和国内各油田前期所做的工作,采用小井眼开采方式,可在一定程度上降低开采成本,实现经济有效开发的目的。小井眼开采方式在钻井方面从技术、设备上都能够实现,降低了开采成本,但这也给后续的小井眼开发带来的一些技术难题;从举升工艺、注水工艺两方面来说,都需要进行相关工艺的研究与攻关,本论文通过研究深井(2000m)条件下的分层注水工艺和测调试工艺,举升系统的优化设计及降低举升系统投资的问题,新型举升工艺的研究,小套管井的油藏监测问题,小套管井措施配套工艺工具的系列化定型,形成了一整套满足小井眼开发需要的工艺技术。
[Abstract]:With the development of oil field, Jilin oilfield after a long period of production, the newly proved blocks belong to the low permeability oil reservoir more, these wells have only a few tons of daily fluid production, if the conventional production mode, it is difficult to achieve economic exploitation. According to the relevant data of foreign countries and the work done in the early stage of each oil field in China, adopting the small hole exploitation method can reduce the production cost to a certain extent and realize the purpose of economic and effective development. The small hole exploitation can be realized in drilling technology and equipment, which reduces the production cost, but it also brings some technical problems to the subsequent small hole development. In terms of lifting technology and water injection technology, it is necessary to study and tackle the key problems of related technology. This paper studies the stratified water injection technology and the testing and debugging technology under the condition of deep well (2000m). The optimization design of lifting system and the problems of reducing the investment of lifting system, the study of new lifting technology, the reservoir monitoring problem of small casing well, the serialization of supporting process tools for small casing well, A whole set of technology to meet the needs of small hole development has been formed.
