The Inspiring Journey of Alraiah Abdelgadir:A Standout Overseas Employee at CNLC

In 2006,at the age of 37,Alraiah Abdelgadir joined the Sudan/South Sudan work zone of China National Logging Corporation(CNLC)as a probationary employee.At that time,his greatest contentment stemmed from having a secure job that enabled his children to attend school without worry,his wife to manage the family with ease,and his parents to peacefully enjoy their retirement years.Over 18 years,he evolved from a "struggling newcomer"to an "ambitious dream pursuer,"now serving as an assistant manager in the work zone.

电容式阵列持水仪CAT在海外油田高含水直井中进行产液剖面测量的适用性分析

在产液剖面测量中,常用的流体识别定量计算方法为电容式持水率计CWH以及流体密度仪器,但只在直井和含水较低(0-48%)的情况下,持水率计CWH和密度仪器的测量精度较高,能够达到理想的测量效果,如果是稠油井,密度仪器分辨油水的能力也将大大降低。当前苏丹油田的大部分生产井含水都高达80%以上,超出CWH的测量范围,且有些为稠油井,所以常规含水仪器很难达到区分油水的目的。Sondex公司的MAPS系列仪器中的电容式阵列持水仪(CAT),具有阵列安装的12个电容传感器,同时测量靠近套管周围流体的电容,从而通过产生的精确的截面图来成像显示油水的分布以及含量,含水测量范围为0-100%,能够达到在高含水油井中进行产业剖面测量的目的。但是CAT仪器通常在大斜度井或者水平井中才能够得到更精确的测量数据,在直井中是否能得到较好的测量效果还有待确认。本文通过对CAT仪器测量原理的介绍以及直井中CAT计算结果与CWH计算结果的对比,分析了高含水直井中CAT仪器的适用性。从几口井的测量结果显示,能够半定量进行含水计算,大致判断产出剖面,与单CWH仪器相比能够得到较好的测量效果。
