The Reserves And Deliverability Evaluation Of Su 10 Block Of Sulige Gas Field

The Su 10 block lies in the northwest of Sulige gas field. Though the exploration and comprehensive research for several years, much changes of the gas bearing area and series of strata has taken place and the reserves of Shan 1 section was not proven in the first reserves reporting, so the recomputation of reserves must be carried out. In view of the reservior characteristic, this paper chooses volumetric method as the appraisal method of reserve, on the ground of which, this paper caculates the reserve parameters, gets the reserve, and evaluats the dependability of the reserve. For the low permeability gas well, it is important to evaluate the productivity, which affects the working system and gas well production. Considering that, choosing isochronal flow test and single point test as productivity appraisal method. Because the accuracy of isochronal flow test is low, it needs to be corrected. The modified isochronal flow test is able to evaluate the productivity precisely. Also, Classifying the appraisal results, and giving a certain production to each category. The results of research can offer references and lay foundation for sequent gas reservoir engineering design and development program and risk investment, etc.
