Detailed Product Description

   The refined reservoir characterization is a technology of integrated study and appraisal of the reservoir on the basis of 3-D quantitative description of variety of reservoir characteristics The final result is to built a 3-D and (or) 4-D reservoir geological module which represents the reservoir geometrical configuration, margin condition, physical characteristics, permeable flowing feature, fluid nature and its distribution.

   Therefore, it is a fusion of geology, seismic, well logging, test and computer technology. It can characterize the trap, reservoir attributes, internal fluid nature and its spatial distribution, thus providing a necessary and reliable geological basis for working out the development strategy and selecting technical measures. The practice proved that each development decision, the adjustment and the implementation are based on the refined reservoir characterization, from the discovery to final abandons of the oil field.

1. refined stratigraphic correlation and division

   On the basis of the reservoir lithology and the fossil, using fully the data from seismic prospecting, well drilling and logging as well as the core analysis, It uses the correlation method of cycle correlation, hierarchical control with stable marker horizon as the control to ensure the match of all levels of depositional cycle and correlation accuracy of oil layer group, sandstone group and the beds. Taking the standard well as the center, It defines the marker horizon and the auxiliary marker horizon with lithological and electrical feature, then carries out the identification, tracking and correlation, builds standard stratigraphic section and correlates all wells on the fault blocks from spot to line, then to area.

2. precise structure interpretation

   It conducts the interpretation of 3-D seismic data on horizon, fault and closure with low height, combining with accurate layer demarcation in many standard wells.

3. study of sedimentary micro-facies

   It studies sedimentary micro-facies and identifies its facies type of major oil sandbed using core and well log data, then builds the relationship between log facies and sedimentary facie, as well as constructs the sedimentary facie cross-section and micro-facies map. Finally, it elaborates on sedimentary feature of different micro-facies and sandbody distribution, constructs sedimentary module, as well as explains sedimentary environment, distribution regularity of micro facies and depositional evolution history in the area.

4. study of reservoir characteristics

   It carries out the researches of lithology, physical properties, connectivity and interlayer and intralayer heterogeneity of reservoir, explains the regularity of vertical and horizontal distribution, estimates reservoir taking the subbed as an unit.

5. geological modeling

   The geological module is the key for oil reservoir modeling. Its accuracy greatly influences the authenticity of the attribute, equal model and numerical simulation. The geology modeling of an optimal block may provide the technical support for tapping potential and adjustment of oil field.

6. Reserves calculation

   It calculates the geological reserves of petroleum by taking fault block, oil measure and subbed as a unit, respectively.

7. Effect appraisal of water-injection development

   It conducts precise estimation on the rationality of development formation, the well pattern, the pressure system of injection and recovery, as well as the effect of yield increasing measures in the main development district on the basis of development history, the present situation and phase division in the entire area, thus explaining the main feature and the rule of oil-water movement, thus giving a concrete comment.

8. Analysis of flooding characteristics

  It studies the flooding characteristic at different watery phases with the help of static and dynamic data of the development.

9. refined reservoir numerical simulation

   The reservoir numerical simulation is the only method of quantitative description of flowing regularity of multiphase fluid in a heterogeneous layer so far and can solve the problem which can not be solved by other methods. The numerical simulation may repeat the calculation of development course with different way and then screens the best development program.

10.researches on the adjustment, tapping potential and dispose

   It carries out the researches on the adjustment, tapping potential and dispose of the profitable area, thus giving an improved proposal after integrated estimation of oil reservoir.
