RIB测井技术在昆北油田的应用

RIB测井技术有效包含了声幅密度测井的所有信息,如声幅、变密度等,能够识别窜槽和孔洞,能够准确反映第一界面水泥环全方位胶结情况。RIB测井技术不同于以往的其它水泥胶结评价方式,它能有效评价水泥胶结的周向固井质量,能测量井周八个扇区水泥胶结曲线、VDL变密度地层胶结波列、升幅衰减曲线。

On the Application of RIB Logging Techniques in Kunbei Oil Field

RIB logging technique can help locate the minute crevices in cementing so as to accurately measure and assess well cementatior;s quality. It can obtain all the irfformation acquired through acoustic density logging such as acoustic amplitudes and variable densities and identify channelings and pores to demonstrate the accurate cementing conditions of cement sheathes on the first interface from all perspectives. Different from other cementing assessing methods, RIB logging technique is able to give a more precise evaluation of circumferential well cementing quality as well as measuring the cementing curves, VDL variable stratum cementing wave trains and growth declining curves of the eight sectors around the wells.
