Optimization Of Ur Group And Favorable Reservoir Prediction Target Area Under The Eight Districts South

Wuerhe reservoir of Karamay Oilfield locates in Baijiantan District of Karamay City,at present, reservoir control factors and real oil domain is not implemented.In this paper, in order to seek and evaluate potential area, development of peripheral drilling deployment,expand the scope for the purpose of exploration and reserves, by means of core,logging,well logging,dynamic monitoring data, based on sedimentology,petroleum geology, reservoir geology,logging geology,reservoir physics theory is based on the previous structure interpretation result analysis,analysis of favorable reservoir seismic and logging the sensitive parameters as the means, through the comparison of multiple parameters inversion test,analysis, the initial establishment of glutenite forward model (DEN initial inversion data body),the lower Wuerhe section of sandstone and conglomerate favorable reservoir distribution and analysis of reservoir control factors, comprehensive evaluation and selection of favorable area, proposed drilling deployment proposal.The main research is as follows:(1)Being well-seismic stratigraphic correlation, analysis results show that wells have good matching relationship between seismic data, well and seismic reflection layer is consistent;only in the structural high part of western poor consistency;(2)The fine structural interpretation,implementation of256well reverse faults,256well East thrust and817well faults,are the early fracture of lower Wuerhe formation,up to top surface of unconformity surface cutoff, extends downward to the lower Carboniferous strata;(3)Establishing the core facies and logging facies and seismic facies and sedimentary facies of the relationship, the sedimentary facies of the lower Urho group, the research into the subfacies and microfacies;(4)Being to reservoir sensitive parameters were screening analysis, draws the screening condition for reservoir:the normalized SP...
