孤东地区浅层气藏开发技术对策

从开发过程中面临的主要矛盾出发，通过气藏工程分析，结合开发实践，对孤东地区浅层气藏的开发技术对策进行了分析。研究表明，通过占高点布井和合理控制气层射开程度，可延长气井的无水采气期，避免气井过早见水；早期防砂和适当控制气井产量可控制气井出砂；通过井下截流，可提高气井自身的携液能力，延长带水采气期；气井出水之后，采取有效的排液措施是进一步延长气井寿命的关键。

Technical development strategies for shallow gas reservoirs in Gudong area

Beginning from the principal contradiction of the development,the technical development strategies for the shallow gas reservoirs in Gudong area are analyzed based on reservoir engineering analysis as well as development practice.The results show that drilling gas wells at top structure and rationally controlling perforation interval of the gas-bearing formations can prolong the water-free gas production period and can avoid premature water breakthrough of the gas wells.Early sand control and rational gas production control can be helpful to solve the sand production problem of the gas wells.Downhole closure may enhance the liquid lifting ability of the gas wells themselves and prolong the gas production period with water of the gas wells.After water breaks through to the gas wells,effective liquid-removing measures are the key technique to prolong the life of the gas wells.
