观音桥区块石炭系气藏开发经验及启示

观音桥石炭系气藏2006年5月天西4井率先投入试采,因生产任务紧张,被迫提高采速生产。气藏本身为边水气藏,直接诱发气井于2008年10月见地层水。由于产水量大,于2010年2月水淹停产至今。部分储量受地层水封割,给后续开发带来了极大挑战。从该气藏开发经验和教训中得到启示:气藏开发应结合自身实际,严格按照合理开发程序和速度,才能取得良好的开发效果。

Development Experience and Enlightenment of Guanyinqiao Block Carboniferous Gas Reservoir

Tianxi 4 well of Guanyinqiao carboniferous gas reservoir was put into trial mining firstly in May 2006.Due to tight production tasks,it was forced to raise the production speed.It is the edge water gas reservoir,and formation water is seen directly inducing gas well in October 2008.Because of a large amount of water produced,it was discontinued since February 2010.Parts of the reserves are sealed cut by formation water,which brings great challenges for subsequent development.We can obtain the enlightenment from development experience and lessons of gas reservoir,i.e.the development of gas reservoir should combine with its actual conditions and follow the reasonable speed and program of development,so that it can achieve good development results.
