Resource Quantity Calculation And Software Realization By Analogy Method In Aksu Area

Under the background of the national 13 th five year plan for resource evaluation,it is planned to carry out the study of oil and gas resource evaluation in Aksu.Based on the geological conditions and survey of exploration in Aksu area,a resource calculation system based on analogy method is developed to further clarify the distribution and potential of oil and gas resources in Aksu area and provide resource basis and technical support for exploration deployment decision-making and medium and long-term planning and deployment.Analogy method is selected as the main evaluation method in this evaluation.Based on the calculation process of analogy evaluation method,the database design of analogy evaluation system is completed.The function design includes five functions:data management,scale area parameter management,analogy standard,evaluation area and achievement release.It is an evaluation system that integrates the functions of geological parameter collection,geological condition evaluation,analogy standard adjustment and multi method resource calculation in the scale area and evaluation area.To achieve the scale area and analogy area one to many and many to many comprehensive analogy single process resource calculation,greatly reduce the time of repeated calculation,and effectively reduce the difficulty of large data correction in the later stage of calculation.Taking the scale area of Kelasu structural belt and the evaluation area of ancient mubezi structural belt as examples,this paper expounds the working principle and working process of the evaluation system.In this evaluation work,on the basis of previous research results,combined with the current situation of oilfield development in this area,14 different types of blocks and zone level scale areas are dissected and established.15 evaluation units are established for the four major structural unit zones and layering systems of Kuche depression,Tabei uplift,northern depression and Tazhong Uplift in Aksu area,and the evaluation system is completed by analogy method Unit resource calculation.According to the calculation results of oil and gas resources of Kuqa depression,Tabei uplift,northern depression and Tazhong uplift,the resources of Kuqa depression are 199626000 tons of oil equivalent,that of Tabei uplift is 2365263825 tons of oil equivalent,that of northern depression is 341020425 tons of oil equivalent,and that of Tazhong uplift is 17503830 tons of oil equivalent.The total amount of oil and gas resources in Aksu area is 308094855 tons of oil equivalent.
