Exploration of logging construction technology for target layers in ultra deep wells in Shunbei oil and gas field
In response to the high logging exemption rate and low data acquisition rate of the target layer in the ultra deep well of Shunbei oil and gas field,there are four difficulties:high risk of logging well control caused by well leakage,inadequate performance of logging tools to meet construction conditions,and lack of supporting logging well control operating procedures and logging technology for lost circulation wells.To im-prove the success rate,starting from preparation,well control measures,and logging technology,the well-bore&logging construction and targeted well control emergency plans should be prepared.The direct push storage technology with high instrument performance and low well control risks is introduced.The applica-tion results indicate that the technology and its supporting solutions has completed nearly 100 well logging operations for the target layer in the Shunbei oil and gas field,and the acquisition rate has increased from 31.25%in 2017 to 93.80%in 2022,which provides reliable logging data for stratigraphic understanding and reservoir evaluation,and is helpful to speed up the oilfield exploration and development.
