Reservoir Evaluation Of Tangjiagou Area Of Wayaobao Oilfield

The reservoir evaluation is based on the control reserves submitted by the pre exploration stage, through the implementation of evaluation work, the reservoir is described by various technical means, and then, to evaluate the geological characteristics, development characteristics and economic value of the reservoir. Through the evaluation, there is no economic value of the reservoir, it is time to end the evaluation of the workload; through the evaluation, with the value of development of the reservoir, to submit proven reserves, and to complete the development plan design.Wayaobao oilfield Tang Jia Gou area, its main production layer is Chang4+5 and Chang6, but the output rate is relatively low, and being a comparatively large amount of pre exploration reserves did not use, it is urgent to carry out further regional reservoir evaluation. This paper makes full use of geological data, core data, well logging data and production data,through the use of practical methods and techniques,geological evaluation and development characteristics of the reservoir in the study area were evaluated,and then the development scheme design was carried out.Aspect of geological, mainly to evaluate the stratigraphic characteristics, reservoir characteristics, reservoir characteristics, reserves etc;aspect of development,mainly to evaluate characteristics of reservoir development, the characteristics of temperature and pressure, the driving type, production characteristics, well net and development technology etc.and the development principle of "overall deployment, priority evaluation, advanced water injection, step by step implementation, real-time adjustment" was put forward; development plan design, combined with the understanding of reservoir geology and development characteristics, practical, to study the implementation details, including drilling, mud logging, well logging, completion, open the oil and gas reservoir, production, water injection wells, reservoir dynamic monitoring, etc, and then put forward suggestions and requirements.The results of this study in Tangjiagou area of Wayaobao oilfield provides a basis for further efficient development, it can also provide reference for the scientific development of other similar wells or oil fields.
