Application of shallow efficient reservoir identification method in Jiyuan oilfield
Reservoirs with shallow burial depth and good reservoir porosity and permeability conditions in the Ordos Basin have high economic development benefits.However,due to the high level of exploration and development in the Jiyuan oilfield,the shallow efficient reser-voirs that have not yet been discovered have characteristics such as strong concealment,small reservoir scale,and local enrichment and high production.Conventional exploration and evaluation methods are difficult to meet the actual needs of efficiency construction.Therefore,based on production practice and the review of old wells,this article innovatively formed five key technologies,including target area prediction technology,fine sand body characterization and prediction technology,fine logging secondary interpretation technology,favorable area selection technology,measure well optimization evaluation technology,and es-tablished a sequence of shallow efficient reservoir identification technologies.The G179 Chang 2 oil reservoir was successfully explored and developed using this technology se-quence,annual average well production capacity of 3.4 tons after reaching production ca-pacity.The results indicate that shallow efficient reservoirs have achieved good results in rolling production efficiency within favorable areas.The research results have guiding signifi-cance for the exploration and development of shallow efficient reservoirs in Jiyuan oilfield.
