Identification And Characteristics Of The Interlayer In The First Member Of Shahejie Formation In The Shawan Formation Of Chun 10 District

Based on the study of reservoir's basic characteristics in the Shayiduan's reservoir of chun 10 oilfield,and according to the geological conditions of the area,believe that three types of interlayers(shale interlayers,properties interlayers and calcareous interlayers)developed extensively in the area.In this paper G?-? interlayers,G?-? interlayers,S1 ?3-?2 interlayers,S1 ?2-?1 interlayers,innner interlayers and their distribution characteristics and the influence of steam stimulationl are identified and studied on the basis of sand body.It is very significant to how to manage the high water-bearing well,design the perforation section and layout the oil well in the later period of the oilfield.Firstly,combined with the geological conditions,conventional logging data,well logging data,core experimental data(rock thin section and Physical property data),the basic characteristics of the reservoir are studied that shows the possibility of the existence of interlayer in this area.Using crossplot method to identify high gamma reservoirs in case see them as interlay.Establishing the logging interpretation model of reservoir by using core analysis data calibration logging curve and based on empirical formula.Through porosity and permeability Relations Act,oil-bearing occurrence and radius of minimum flow pore throat,we ensure lawer limit of porosity and permeability.To analyze the logging response characteristics of each type of interlayers then we establish the standard of identifying interlayers.Based on the identification of single well,we study the distribution characteristics of the interlayer by the vertical and the horizontal plane.To combine with production data to determine the impact of the interlayer on the development of steam stimulation.Through the study of the basic features on the reservoir,we determine the interlays' types,identification method of interlay and vertical and plane distribution characteristics of interlay,combined with thermal dynamic production data analysis of the effect of interlayer on steam stimulation,provides a reliable logging interpretation for further oilfield development.
