Reservoir Characteristics And Logging Evaluation Method Research Of Kuidong Block In Kuihuadao Oilfield

In this paper,the oil-water layer recognition for the Kui Dong exploration and development process has exposed some problems,as well as the actual situation in the area of low resistivity reservoirs development,the geological features of the beach area reservoir understanding of the basis to carry out the intrusion of salt water slurrymechanism and rock physics experiments,the main controlling factors of low resistivity reservoir in a clear work area;at the same time,conventional logging and array induction,magnetic resonance MDT image logging as a means to carry out the beach area of low resistivity reservoirs measuredwells the Methods of Evaluation of identification research to,the establishment of low resistance oil and gas layer well logging identification method,the oil and gas layer well logging quantitative criteria for the classification and reservoir parameters logging interpretation model,improve the well logging of oil and gas layer to explain complies withrate and reservoir parameters log interpretation accuracy,and provide basic data for proven reserves and follow-up exploration and development.Through the mechanism of the Kui Dong Causes of low resistivity reservoirs,saline mud soaked,high clay content,clay high added conductive to the formation of the main reasons of the region of low resistivity reservoirs.Four property relations on the basis of the analysis of the causes of low resistivity reservoirs,the establishment of quantitative criteria for the classification beach area of low resistivity reservoirs logging qualitative identification and the effective thickness of the reservoir;in the core-scale logging on the basis of shale content,porosity,permeability,saturation,reservoir parameters log interpretation model.In this paper,the test oil drilling the Kui Dong,trial mining data and analyzed,combined with the achievements of the Kui Dong geological knowledge to establish a statistical model of the reservoir productivity index and reservoir permeability think oily amplitude,lithology andthe physical properties of reservoir capacity.Since the permeability is a comprehensive reflection of lithology,physical properties,therefore,to accurately determine the permeability is the key to productivity prediction.Use of core analysis data,magnetic resonance imaging array sensor and MDT research results,the layer plane radial steady seepage law principle to establish oil and gas production logging classification standard,and Kui Dong drilled to a total reservoir capacity forecast is fairly effective.
