Dessert Optimization and Oil Potential Analysis of M9 Block in W Oilfield

Abstract

Abstract This article first explains the fine structure of the M9 block, and the encryption equal value line is finely constructed into a diagram to identify the micro -amplitude structure. Use the block drilling to complete the inner plane and vertical distribution statistics of the block. Essence Using the seismic section interpretation technology, multi -attributes and detailed portrayal of the broken layer, implement the overall structural characteristics and TEZHEN characteristics of the block, carry out multi -attribute analysis and research on the oil layer sandstone group, preferably seismic attributes sensitive to the development of sandstone, and obtain each through the calculation of the well -shaking combination calculation. Unit sandstone thickness quantitative prediction diagram, analyze the characteristics of the oil and water distribution of the block, combine the favorable positions of the well deployment, combine the characteristics of the structure, the break, and the sandy body distribution, and prefer the dessert area. The original large sedimentation law understands that the “single structure favorable oil control zone” is required to re -evaluate the high -risk zone, and combine the fine structure interpretation with the sand body reservoir prediction. Improve the success rate of the evaluation control well in the dessert area, and follow the deployment of the block well after the guidance.
