通过对电缆测井、随钻测井和过套管测井系列施工条件及资料对比分析发现,电缆测井系列施工条件相对容易,测井项目丰富,缺点是获得的地层测井参数受钻井液侵入影响大,精确度相对较低,随钻测井系列适用于大斜度定向井、水平井测井,测井资料因不受钻井液侵入影响,可获得较精确的地层参数,缺点是纵向分辨率较低,在复杂地面和地下地质条件下,过套管测井系列是电缆测井、随钻测井系列的有效补充,同时也是进行油藏管理的一种有效的测井系列,通过过套管测井,可详细地了解油藏的动态变化以及发现漏失或隐蔽的油气层。
Through the comparison of cable logging, logging while drilling and over-cased logging series construction conditions and data comparison, it is found that the cable logging series construction conditions are relatively easy and the logging items are abundant. The disadvantage is that the logging parameters obtained are affected by drilling fluid Invasion impact is large and the accuracy is relatively low. The LWD series is suitable for large-scale directional well and horizontal well logging. Because logging data is not affected by drilling fluid intrusion, more precise formation parameters can be obtained. The disadvantage is that longitudinal Low resolution, under complex ground and underground geological conditions, over-cased logging series is an effective complement to cable logging and logging while drilling, and is also an effective logging series for reservoir management through Cased hole logging provides a detailed understanding of reservoir dynamics and the discovery of missed or hidden reservoirs.
