Wuqi Oilfield Of Yanchang East Wu Cang Bao6-9Comprehensive Evaluation Of Reservoir Length

Through the chang6、9reservoir fine description, study of reservoir distribution,according to the principle of economy and high efficiency through comprehensive study andnumerical simulation to determine the development way and scheme deployment; Fromoptimization of drilling, oil extraction, and the ground system research on the aspects such asdesign, select suitable for block development and production needs of scientific and practicaltechnology, making scientific and reasonable overall development project plan, to providereasonable and efficient development demonstration area of technical support, to ensure thatfurther improve the level of demonstration area construction capacity and water drive recoveryfactor reached the leading level of the domestic similar reservoir, to extend the efficientdevelopment of oilfield other blocks provide exemplary role. The project’s main task is to:application of yanchang formation in shanbei region reservoir accumulation theory andresearch experience, to chang6, Wu Cang fort east oil region chang9reservoir fine reservoirdescription, reservoir comparison as well as the comprehensive evaluation of reservoir. Toreservoir, the concealment of the delta reservoir accumulation in geomorphology theory, acomprehensive assessment for scrolling development goals clear advantage. The district6reservoir as the concealment of the delta reservoir, but as a result of delta front facies sandbody appears mainly in northern area, and give priority to with distributary channel, so chang6small sand layer thickness, poor physical property, development is difficult; chang9reservoir belongs to lithologic reservoir in the area belongs to regional enrichment, because athalf deep lake environment, has the good source rocks, and the development of underwaterturbidite fan provides a good reservoir, and its so chang9subaqueous fan development zone isthe next step exploration and development of key areas.
