Fine Description Of Triassic Reservoir In B181-B468Wellblock In HQ Oilfield

Fine reservoir description research combined with geology, geophysics, reservoirengineering and numerical simulation technology and other disciplines, to study the remainingoil distribution features and law as the core, by conducting comprehensive reservoircharacteristics, to study the dynamic aspects of development to establish fine3D geologicalmodel of reservoir, and then through the establishment of numerical model to simulationprojections for oilfield development plan and development index and optimization,optimization of production measures and optimizing development plan.Since B181-B468wellblock HuaQing oilfield put into production, although the overallproduction conditions are relatively stable, but also began to reveal some productioncontradiction, for example: the exploited horizon, more complex, injection-production relationbetween part well group decreased fluid producing, low single-well production, displacementsystem is difficult to establish effective pressure and so on, seriously affecting the effects ofthe oilfield development, this paper probes into the above problems according to therequirements of fine reservoir description and ideas for research.This paper through the celebration of HuaQing B181-B468oilfieldwellblock Triassicgeological characteristics of the study, divided into comparing unit, analyzes the peace of thedistribution characteristics of sedimentary micro-facies profile, the evaluation of reservoirheterogeneity and the flow unit classification evaluation, application of a variety of methods toevaluate the block reservoir development effect, finally through the reservoir3D geologicalmodeling and numerical simulation model establishment and fitting to determine remaining oildistribution features, so as to develop the stable technology policy.
