| Reservoir description technique is a new subject, comprehensive evaluation abroad inrecent20years development of the reservoir. It is based on the structural geology,sedimentology, mathematical statistics theory, the computer as a means, through theinteraction of geological, seismic, logging and testing technology of multi-disciplinary,multi-level, From the three-dimensional space to qualitative, quantitative, fine description ofthe reservoir properties.For the SuoTu oilfield, although it has been done in detail, but the understanding degreealso remain in a relatively shallow level, Based on the fine description of reservoir oil,effectively to map geological, structure, deposition, accumulation and enrichment area ofin-depth research and understanding, under the guidance of high-resolution sequencestratigraphy, the phase control, cycle comparison principle, the formation division basis, themain story in GⅠ, GIV is divided into5layers,8sedimentary units. In the regionalsedimentary system on the basis of analysis, phase of I Ai, lithofacies, seismic, GⅠ, G IVgroup was divided into1kinds of facies,2subfacies and6microfacies. The reservoir poretypes are mainly undeveloped intergranular pore, the main oil-bearing intervals generally lowporosity, low permeability reservoir. In the analysis of basin, in-situ stress cracks based onthe core observation and description, take, deviation analysis, and the adjacent oil analogyand fracture mechanics based on prediction method, research thought, crack suotu oilfield isrelatively developed, and more development in the near fault. Through in-depth research,study on the favorable block development suotu oilfield, north of the study area the mainblock for small anticline, an area of about2.0km2, area of well control degree is high, thegeological understanding more clearly, and few faults in the study area, conducive to thedevelopment of network deployment, favorable development block. |
