Research on Liquid Loading Diagnosis Technology of Horizontal Well in Ledong Gas Field
摘要
Abstract
Because of lacking liquid loading monitoring methods and targeted theoretical models in offshore oil fields,a liquid loading diagnosis technology of horizontal well for Ledong gas field is established.It includes pre-diction models of critical liquid-carrying flow rate and pressure drop gradient, which considers the impact of the deviation angle.The results show that the maximum critical liquid-carrying flow rate and pressure drop gradient ap-pear in deviated hole,especially in the hole with deviation angle of 30°~50°,leading to liquid slippage easily.By liquid loading diagnosis technology,the liquid accurate situation in Ledong gas field is diagnosed,with 100%accura-cy rate.The liquid loading height of L3 well is calculated,which successfully helps caber foam drainage in L2 well. The liquid loading diagnosis technology of horizontal well provides scientific basis for gas recovery by water drainage.关键词
