为了精确测定随钻测井仪器在井眼中位置及井眼尺寸(井径),研究了利用随钻方位密度测井响应计算间隙(仪器壁和井壁的距离)和井径的方法。首先,利用蒙特卡罗模拟建立仪器的计算模型,并将模拟结果和实验数据进行了基准检测;其次,研究不同条件(即地层密度和泥浆密度变化)下间隙尺寸对探测器的影响;最后得到了间隙尺寸及井径的计算方法。结果表明:探测器测量的密度受间隙、泥浆密度、地层密度的影响,当地层密度与泥浆密度差(介质密度差)一定时,地层密度与远密度之差(测量密度差)和间隙成正比关系;通过测量的密度、地层密度和泥浆密度计算,可以获得间隙尺寸,利用仪器和井眼、间隙的几何关系计算井径,精度达到0.1 cm。
Background
2
Borehole diameter (bore diameter) and standoff are important parameters that affect the precision of the logging while drilling (LWD) tool.
Purpose
2
This study aims at the method of accurately calculating the instrument-to-hole standoff and borehole diameter by using the azimuthal density LWD.
Methods
2
A Monte Carlo simulation was used to establish the instrument calculation model
and the simulation results and experimental data were benchmarked. Then
the effect of 0~5 cm standoff on the response of the detector was studied by changing the standoff size
formation density and mud density. Finally
the standoff size can be calculated by measuring the detector's density
formation density
and mud density whilst the caliper can determined by using the geometric relationship.
Results
2
The density measured by the detector is affected by the standoff
mud density
and the density of the formation. When the difference between the formation density and the mud density (difference in the medium density) are constant
the difference between the formation density and the far density (measured density difference) are proportional to the value of standoff. The calculation accuracy of borehole diameter reaches 0.1 cm.
Conclusion
2
This study provides a theoretical foundation for calculating standoff and borehole diameter in practical projects in the future.
