Research On The Fine Description And Deployment Adjustment Of Huan 17 Block In Dujiatai Reservoir

Huan 17 block is located between Jinzhou city and Panjin city(Liaoning provinc e), of which south is Bohai bay. The structure is located in the southwest of the wes t slope, Western Sag, Liao graben basin, of which north is Jin 99 block, south is Jin27 block and east is Jin 4 block. The construction area is about 4 km2.The block main problems is that oil wells in reported area of the region all been discontinued due to cover bad oil wells, high moisture and other reasons, and the re st of the regional structure and reservoir knowledge is not very clear. In order to enh ance the developing effect of the block, it is necessary to carry out research to deepe n understanding of geology, find out the distribution of the remaining oil, and propos e the next step to develop countermeasures, which focus on structure and reserve of t he eastern well region. based on previous research and rich array of three-dimensional seismic, drilling, logging, core, oil test mining, development trends, and oil analysis data, fully using of geological, geophysical, and development of dynamic data, develo ping the advantages of multi-disciplinary joint research, and playing the new theories, new technologies and new methods of multi-disciplinary of sequence stratigraphy, sedi mentology, petroleum geology, geophysics, etc.to research based on petroleum geology theory, the structural features within blocks, sand distribution, reservoir characteristics,fluid characteristics, the relationship between oil and water pressure system can been find out, the effect on waterflooding can been evaluated and the direction of adjustm ent and block development potential can been identified to improve block developmen t effect.Based on block structure, the characteristics of the reservoir and the reservoir reu nderstanding, and according to main problems of the block, the adjustment are put for ward for two secondary fault block deployment, plan adjustment 2 wells, and 3 of ex isting wells reperforating stopes measures, further perfecting injection-production well s pacing, to improve reserves producing degree.
