Research On Reservoir Heterogeneity Of The 3^rd Member Of Hetaoyuan Formation In Shuanghe Oilfield

This article synthesis using modern sedimentology theory,based on the research in deposits in the micro characteristic of the double river oil field fan delta front,using the material about oil well logging and core analysis,to do the research about reservoir microscopic heterogeneity,the level heterogeneity,the level heterogeneity as well as the plane anisotropic characteristic of double river oil field nucleus three sectionsⅢin oil line。The reservoir microscopic heterogeneity research,observed the analysis detritus pellet ingredient through the mirror,to determine the hole,throat's size,the distribution,the disposition and the connectivity and the rock component,the pellet arrangement way,the matrix content and agglutinated the type and so on , to show the reservoir micro heterogeneity。In the level the anisotropic research,according to the reservoir lithological character and the electrical characteristic,to divide the level in the band three kinds,to count in the single sand body the band integer,to accumulate band thickness,the band frequency and the band density,according to the band the micro granulated substance in vivo frequency and the density,to summarize the band distributed characteristic。Then explain the reservoir the non-isotropic characteristic through in the different rhythm of sedimentation type graduation and the computation sand body the penetration coefficient coefficient of variation,the advance coefficient as well as the grading。The level the anisotropic research,basing on the lamination factor,the sandstone density and the overlap coefficient describes the sand body growth and the distribution;using the master curve correlation method to determine that the insulation lithological character and thickness and summarize the insulation distributed characteristic。Granulated substance body's plane heterogeneity,according to deposits the micro granulated substance body to count its geometry shape parameter differently;according to each well's well logging interpretation material to obtain a group to reflection that the reservoir characteristic the parameter which changed in the plane,including the reservoir thickness distribution,the porosity as well as the penetration coefficient,and became the chart。According to deposits differently the micro granulated substance in vivo Shan Shati growth situation and the growth characteristic total invoice granulated substance body to summary the deposits micro controls in the plane distributed rule。Selecting the typical characteristic joint well section plane,analyzing the section plane,restoring the old extensively the environment of deposition,to determine the environment of deposition in the time,the spatial evolved rule and instruct the source analysis。And according to each well the log information,to process various parameters of the reservoir。Then,carries on the interpolation according to the gram Riggin interpolation to the well,to obtain a group to reflect that the reservoir characteristic the parameter chart which changed in the plane,including reservoir thickness distribution,porosity as well as penetration coefficient plane mop,total invoice granulated substance body plane distribution and link rule。Based on the above research,appraisal reservoir's heterogeneity has the high reference value to the oil-field development adjustment。...
