模拟分析了近钻头伽马成像测井仪器穿过倾斜界面进入高放射性泥岩层的扇区成像特征 …

Optimal field development often entails placing the wells in prescribed locations within the
reservoir. An error of a few meters in height above the oil/water contact or with respect to the …

The work is dedicated to the development of a new downhole resistivity microimaging tool
for logging while drilling (LWD) in oil and gas wells. The purpose of this research is to create …

High resolution electrical imaging is an important component for the detailed geological
interpretation of logs such as structural, sedimentological, or geomechanical analysis …

A novel method for quantitative geosteering by using azimuthal gamma-ray logging is
proposed. Real-time up and bottom gamma-ray logs when a logging tool travels through a …

An 'Intelligent'wired drill-pipe system has recently been used on a large offshore
development in North West Australia for Apache Energy Limited. The IntelliServ® network is …

На основе векторного метода конечных элементов разработан алгоритм трехмерного
численного моделирования сигналов нового отечественного прибора–микроимиджера …

常规随钻测量工具的测点离钻头较远, 无法及时准确判断钻头处的地层岩性和倾角,
储层钻遇率较低, 也不满足储层精确描述的要求. 为此, 研究了高转速条件下地层伽马射线动态 …

Transmission of real-time data acquired during drilling from downhole MWD or LWD sensors
is now an integral part of almost all drilling operations. The value of the data received …

Unconventional shale environments have traditionally been evaluated with wireline logging
tools. Recently, it has become more common to evaluate these wells with logging-while …
