摘要
塔河油田碎屑岩区块一直以中生界为主要目标产层,塔中地区顺9区块志留系柯坪塔格组的油气突破,不仅为塔河油田带来新的产能阵地,同时开拓了该区新的勘探领域——古生界志留系砂层。该区储层属低孔低渗,砂泥岩阻抗部分叠置,给储层预测带来较大难度。反演作为一种常用的储层预测手段,相对于其他属性方法,可做到定量预测储层。本文以塔河托甫台为例,利用反演法对该区砂体进行定量预测,为探井部署提供有力依据。
The main target of Tahe oilfield clastic block has been the Mesozoic.The oil and gas breakthrough of Siluri-an Kepingtage in shun9 well block not only brings new capacity positionsarea to Tahe oilfield,but also explores new ar-eas of exploration-sandstone of Paleozoic Silurian.The reservoir of this area is low porosity and low permeability,the im-pedance of sandstone and mudstone is partially superimposed.So,the reservoir prediction has great difficulty.Inversion as a common method of reservoir prediction can be quantitative with respect to other property methods. This paper uses the inversion method to predict sand body quantitatively for Tuofutai block of Tahe,and provides a strong basis for well deployment.
