Jin 33 Block Geological Research And Residual Oil Evaluation

Jin 33 Block developed since 1981 by natural energy,development reservoir are Xing-long and Re-he layers,by influence of the tectonic and sedimentary environment,the fault block development contradiction is outstanding,Xing-long reservoir edge-bottom water energy is sufficient,now the reservoir is in high water cut period,the remaining oil dispersed,adjustment is difficult.By influence of the turbidite depositional body of ES3 which is Re-he reservoir,oil well production is low.For further mining block residual oil and gas potential,take reservoir study.Stratigraphic division and correlation adopt seismic geological method,use SeisWare interpretation system for fine structure interpretation,and then take sedimentary facies analysis and case study for the development of reservoir.Combined with the tectonic evolution,fault distribution,reservoir prediction,accumulation law research,etc.,to carry on the comprehensive evaluation,and provide strong technical support for next step exploration.Stratigraphic classification use Jin 33 block drilling data,considering the work area sedimentary characteristics and formation thickness,by using well completion logging from different parts of the slope profile,set up north south east west stratigraphic correlation profile.The block tectonic background is complex,the region layer buried depth is with big difference,the seismic data quality is poor.The conventional,a single research method is difficult to achieve the accuracy requirement of the explanation,therefore,in this work we use multiple modules in the system of Landmark workstation,combination with drilling,oil test data for the fine structure interpretation of seismic data in the area.According remaining oil distribution study,combining with the understanding of the comprehensive geological study,put forward the corresponding adjustment of deployment and the salt solution,has good potential in effect.
