【摘要】：油藏评价是在预探阶段所提交的控制储量基础之上,通过评价工作量的实施,利用各种技术手段对油藏进行描述,从而对影响油藏的地质特征、开发特征以及经济价值做出评估。对于经过评价,没有经济价值的油藏,要及时终止评价工作量；对于经过评价,具有开发价值的油藏,要提交探明储量,并完成开发方案设计。瓦窑堡油田唐家沟区域,其主要开发层位为长4+5和长6,目前开发难度较大,采出率较低,还存有较大量预探储量没有动用,亟待开展进一步的区域油藏评价工作。本文充分利用研究区地质资料、岩心资料、测井资料及生产动态资料,用切合研究区实际的方法和技术,对研究区油藏进行了地质评价、开发特征评价,进而展开开发方案设计。地质方面主要对油藏地层特征、储层特征、油藏特征、储量等进行了分析和评价；开发特征方面主要对油藏开发特征、温度压力特征、驱动类型、生产特性、井网及开发技术工艺等进行了分析和评价,提出了“整体部署、优先评价、超前注水、分步实施、实时调整”的开发原则；开发方案设计,结合对油藏地质及开发特征的认识,切合区域实际,对研究区开发方案做出了设计和部署,并对方案实施细节,包括钻井、录井、测井、完井、打开油气层、投产、注水井实施、油藏动态监测等方面,提出了详细的建议和要求。本文的研究成果对瓦窑堡油田唐家沟区域进一步的高效开发提供了依据,也可为其它类似井区或油田的科学开发提供借鉴。
[Abstract]:Reservoir evaluation is based on the controlled reserves submitted in the pre-exploration stage. Through the implementation of the evaluation workload, various technical means are used to describe the reservoir, thus affecting the geological characteristics of the reservoir. Evaluation of development characteristics and economic value. For the reservoirs with no economic value after evaluation, the workload of evaluation should be terminated in time, and the proven reserves should be submitted and the design of development schemes should be completed for the reservoirs with development value after evaluation. In Tangjiagou area of Wayaobu Oilfield, the main development horizons are Chang45 and Chang6. At present, the development is difficult, the recovery rate is low, and a large number of pre-exploration reserves are not used, so it is urgent to carry out further regional reservoir evaluation work. This paper makes full use of the geological data, core data, logging data and production performance data of the study area, and makes use of the practical methods and techniques in the study area to carry out the geological evaluation and development characteristic evaluation of the reservoir in the study area. Then the development scheme design is carried out. Geological aspects mainly analyze and evaluate reservoir stratigraphic characteristics, reservoir characteristics, reservoir characteristics, reserves, etc. Development characteristics mainly include reservoir development characteristics, temperature and pressure characteristics, driving types, production characteristics, etc. The well pattern and development technology are analyzed and evaluated, and the development principles of "overall deployment, priority evaluation, advance water injection, step by step implementation, real time adjustment" are put forward, and the development scheme design, combined with the understanding of reservoir geology and development characteristics, is put forward. In accordance with the regional reality, the development plan of the research area is designed and deployed, and the details of the implementation of the scheme are made, including drilling, logging, logging, completion, opening oil and gas layers, putting into production, implementing water injection wells, monitoring reservoir performance, and so on. Detailed suggestions and requirements are put forward. The research results of this paper provide the basis for further high efficiency development in Tangjiagou area of Wayaobu Oilfield, and can also be used for reference for the scientific development of other similar well areas or oilfields.
