Study On The Ultra-low Permeability Reservior Enrichment Area Optimization In Haituozi Area

In view of the difficult that ultra-low permeability reservoir is multiple source, high shalecontent, thin sand body, side faster, low single-well-production and poor development benefit,through the technology research of the lithology reservoir study, combines with the fracturingtechnology, it formed the ultra-low permeability reservoir enrichment area optimization andefficient development technology series, and achieved the continuous and effectivedevelopment of unused resources in Haituozi area.Through the study on sedimentary microfacies and relationship between production andmicro-characteristics and the deeply study on ultra-low permeability reservoir, it has beenclear about the production factors. And that0.47μm-throat radius,0.3mD-permeability is thetechnical threshold of effective development in Haituozi area.Study on reservoir character parameter inversion, permeability of sand body, andetechnology research of the lithology reservoir, the major reservoir distribution has been clear.It finaly concealed leading technology of subtle lithologic reservoir enrichment areaoptimization.
