Application of Intelligent Cable Production Technology in Multi Layer Combined Production Directional Wells:Taking B38 Well in Bohai X Oilfield as an Example
Due to depleted development,the reservoir degassing of B38 well after 2 years of production caused oil and gas interference affected the normal production of the well.Due to limitations in well conditions such as high inclination,multiple layers,and long well sections,this well does not have the ability to apply"Y"type separation production columns for testing and gas control measures,and requires the application of new oil production technology.The intelligent sub production technology with cables can be applied to various well types,and real-time monitoring and production control of production parameters such as production,pressure,and temperature in each layer of the oil well can be achieved through ground controllers.At the same time,it also provides a large amount of data support for reservoir analysis,evaluation,and decision-making.By applying this technology,the B38 well accurately identified the degassing interval,took measures to close the main gas producing interval and control the secondary gas producing interval,slowed down oil and gas interference,and restored normal production of the oil well.This technology has been applied 10 times in Bohai Oilfield,with significant oil increase effect and good promotion value.
