摘要
气井积液是气田开发过程中的一个比较严重的问题,当气井存在井筒积液后,产气层和管柱内形成气水两相流动,压力与能量的损失也将逐渐增大,从而导致气井自喷能力逐渐减弱,产量迅速递减,最终因井底井筒积液而水淹停产。恢复气井的正常生产,需建立一套适用不同类型积液井的排水采气配套工艺技术,确保气井能够及时恢复生产。为此对于气井积液的识别与排水采气工艺优化研究对整个气田气井的开发具有重要的现实意义。
The accumulative fluid is a serious challenge in the development of gas wells, where gas and fluid phases both exist in pay zones and pipes full of flowing fluids, hence the loss of pressure and energy increases. As a result, the gushing capability and production rate of gas wells decrease, which turns them to be surging wells even abandoned wells suffering from the serious accumulation of borehole fluids. It is of great importance to recover normal production and establish series of integrated technologies about drainage gas production, so that gas wells may be developed more efficiently. Therefore, the verification of accumulative fluids in gas wells and optimization of drainage gas production techniques are playing significant roles in the overall development of gas fields.
