SN油田S19块阜三段储层相控测井解释与评价

Logging Interpretation and Evaluation by Deposition-facies Control of Ef_3 Reservoir in S19 Block, SN Oilfield.

如何提高复杂小断块油田的测井解释符合率是长期以来困扰人们的一大难题。通过对SN油田S19块关键井S19-1阜三段储层岩心相、测井相的研究 ,并通过高分辨率层序地层对比和多井相分析 ,提取反映各沉积微相岩性、物性、电性的GR、AC、Rt参数建立相应的解释模版 。

How to improve accuracy of logging interpretation of small complicated fault blocks is a tough problem. Through studying Ef 3 reservoirs core facies, logging facies of key well S19-1 in S19 block of SN oilfield, multiwell-facies analysis and correlation of sequence stratum with high resolution, we got three parameters (GR, AC, R t) related to lithology, physical and electrical properties of rocks for corresponding depositon-facies controlled interpretation plots, thus realizing facies-controlled log interpretation and multi-well evaluation. The result obtained from practical application is good, which provides a new method for logging interpretation in the future.
