高温井径伽马磁定位组合测井仪在冀东油田的应用

Application of High Temperature Caliper-gamma-CCL Logging Tools to Jidong Oilfield

多臂井径成像测井仪是用来评价套损、检测射孔质量和检测套管状况的仪器。两次起下仪器增加劳动强度,设计一种伽马磁定位仪器,组合多臂井径仪器,一次下井完成井径、伽马和磁定位信号的录取。仪器研制完成后,在大庆油田进行了现场试验,仪器能在150℃/80 MPa下稳定、可靠地工作。在冀东油田完成10口井的生产任务,能准确地测量套管腐蚀变形程度。该仪器能为监测套管的状况,延长油水井的使用寿命,提供详实可靠的资料。

The multi-arm caliper imaging logging tool is used to evaluate the casing damage, detect the quality of the perforation and the cas- ing. Since the two-time lifting and lowering of the tool can increase the intensity of labor, a type of gamma-CCL tool is designed to be com- bined with multi-arm caliper instrument. Hence one-time lowering of the tool could complete the extraction of well diameter, gamma and CCL signal. After the completion of the instrument, field experiments are carried out in Daqing oil field. It has been proved that the instru- ment can work stably and reliably under 150/80MPa. The production taskes of 10 wells in Jidong oilfield show the new instrument can ac- curately measure the casing corrosion and deformation degree. It can provide detailed and reliable basis for monitoring casing conditions and prolonging the service life of the oil wells.
