Analysis of logging parameter model of Jurassic complex reservoir in Xinjiang Shenquan Oilfield

The study discusses the characteristics of Jurassic reservoir in Shenquan Oilfield Xinjiang. Qiketai Sanjianfang formation mainly develops delta front facies and shore shallow lake sand bodies.The lithological are fine sandstone siltstone, physical properties target layer medium porosity permeability. space is pore type, composed secondary pores, including intergranular dissolved intragranular pores intercrystalline with good connectivity between pores. According to analysis data well logging, core analysis, production performance DST Oilfield, porosity, permeability water saturation models established respectively:The interpretation model by using acoustic wave shale content; parameter realized applying graph based cluster method neural network algorithm. oil obtained Archie formula. logging results, it can meet needs evaluation, oil-water distribution original geological reserve parameters. After analyzing calculation method, considered that Xinjiang has better properties.
