Research on direct push storage acoustic logging evaluation methods for ultra-deep reservoirs:A case study of fault-controlled carbonate reservoirs in Fuman Oilfield,Tarim Basin
摘要
Abstract
The new direct push storage logging technology has strong applicability and high well control safety,effectively solving the logging data acquisition problem under complex well conditions such as high temperature and high pressure,easy blowout,and frequent lost circulation in ultra-deep wells of Fuman Oilfield.However,the well type of Fuman Oilfield,dominated by highly deviated and horizontal wells,makes the instrument measurement not centered and the motion speed of the instrument not constant,which greatly affects the quality of direct push storage slowness,and the reservoir grading evaluation method mainly based on acoustic waves is incomplete,seriously affecting the evaluation of logging reservoirs.Based on the characteristics of direct push storage acoustic instruments,a method for extracting the direct push storage slowness of the P-wave and S-wave and processing the relative amplitude of the mode wave was developed.A reflection imaging processing method near the wellbore in horizontal wells was established,achieving effective evaluation of fault-controlled carbonate reservoirs in the wellbore and around the wellbore.The distance between the wellbore was calculated,and 3D imaging of the reflectors was performed.The effectiveness of the reflectors near the sidetrack wellbore was comprehensively evaluated.Those technologies have been applied on a large scale in the ultra-deep fault-controlled carbonate rocks of Fuman Oilfield,supporting the comprehensive effectiveness evaluation of reservoirs in the wellbore,around the wellbore,and near the wellbore.The logging interpretation accuracy rate has reached 96.7%,and the application effect is significant.关键词
