注硼中子寿命测井施工工艺设计方法研究

On Technical Design of Boron-injection Neutron Decay Logging Operation

注硼中子寿命测井工艺包括注硼施工工艺和测井施工工艺 2部分。应用研究表明 ,从现有仪器性能、产层地质状况、井眼环境等方面着手 ,针对注硼浓度、注入压力选择、测井时机把握等进行精心设计 ,能够有效改善和提高注硼中子寿命测井在产层动态参数监测和评价应用中的效能。

Boron-Neutron decay logging includes boric acid injection technology and logging operations. Research shows that, in the light of existing logging tool's performance, geologic settings of producing zones and borehole environment, etc.,carefully designed concentration of boric acid injection, injection pressure, logging time control help us effectively improve performance monitoring and evaluation of the producing zones.
