The Study Of Geological Description In Guancaojian Area

Guan caojian oil region located in the in zhe village of jingbian Yang mijian,2km east ofyang mijian oil region, southwest is adjacent to changqing JingAn oilfield, has abundantgeological reserves Now the block evaluation is still under development stage, The ratio oftest well is is very small, the overall understanding of reservoir is not comprehensive.According to current situation of the region of research, this paper based on the analysis ofthe existing data, combined with the actual,reserves re-calculation and secondaryinterpretation for logging data is carried out based on sedimentary and petroleum geologyscience theory. Sand body distribution macro law is analyzed through detail research onprevious results, full use of logging data to division and correlation and drawing phasediagram of single well phase, even with well profile well and plane phase with coreobservation and logging data. Reservior microscopic characteristics is analysed by ordinaryslice data and physical testing. Reservoir classification and evaluation standard is establishedand small layer should be evaluated through integrating reservoir macroscopic andmicroscopic features. These initiatives ensure a steady increase of oil productiomn and oilproduction rate to a reasonable level in oil production area. The increasing and stable oilproduction target achieving provides an exemplary role for other block effective exploitationin Jingbian oilfield.
