To Describe The Reservoir About Fan Xue Chang4+5,6Blocks Of Jiyuan Oilfield

In this paper, learn Jiyuan Oilfield Fan block reservoir, for example, the use of the latesttheories of modern reservoir description as a guide, the application of petroleum geology, highresolution sequence stratigraphy, sedimentology, structural geology, reservoir geologymanagement theory and research technology development technology multi-disciplinaryresearch conducted reservoir fine description Fan learn reservoir. Comprehensive study usingthe latest3D seismic, logging, logging, drilling, testing and analysis data, combined withscience block Jiyuan Oilfield Fan reservoir faults, tectonic crushing, sand developmentunstable characteristics, using high-resolution a variety of new methods of sequencestratigraphy rates, reservoir geology, reservoir flow units and other fine description of, andproduction of oil combine with dynamic data from multiple levels of structure, deposition,reservoir, and aspects such as mobile unit to carry out the study Jiyuan Oilfield block Fanreservoir fine description and conducted research and development of reservoir performance,the last of Jiyuan Oilfield oil Fan school district developed technology was arranged for JiyuanOilfield Fan school district to develop oil reservoir there are important theoretical and practicalsignificance. Achievements made in this article are:(1) According to the sedimentary faciesidentification marking systems: think long4+5, Chang6oil are in delta front facies, researchhorizons are from north to south;(2) Fan seniors.4+5, Chang6oil reservoir space mainly forprimary porosity, secondary porosity and fractures three types; a low-hole, low permeabilityreservoir lithology, the original drive type elastic solution gas drive;(3) Fan learn geologicaloil reserves of1736.40×04t; reasonable optimal value (4) Fan seniors4+5reservoirinjection-production ratio should be between1.0to1.1, the maximum injection wells wellheadinjection pressure is18.0~20.0MPa, reasonable considering the wellhead injection pressureshould be about12.0~14.0MPa, reasonable production pressure should be controlled between10.1~11.1MPa.
