摘要(Abstract)：

徐深气田D区块为含底水的火山岩气藏,部分边部气井产出地层水,影响气井产能和气田开发效果。针对D区块不同出水类型的气井,以"体考虑、分类治理"为原则,制定了适合该区块的合理开发对策。考虑压降单元、断层分割、储层连通,划分6个井区,在各井区实施"低排高控"整体开发对策,保持高部位气层的压力,减缓边、底水的锥进,对单井生产尽量做到"产气量、压力、产水量"三稳定,避免底水快速锥进。结果表明:D区块实施控水采气、合理配产后,延缓了边底水过快侵入气藏,延长了气井无水采气期。
Block D of Xushen Gasfield is the volcanic gas reservoirs with the bottom water.Because of the formation water produced in the gas wells on the partial sides of the block,the well productivity and developed effects are affected.In the light of the gas wells with different types of the produced water,according to the principle of"overall consideration and classified management",the reasonable developing strategies adopted for the block were established.Considering the pressure dropped units,fault segmentation and reservoir connectivity,six well blocks were divided.Each well block takes "low discharge/drainage and high control"as the overall developing strategy,the reservoir pressures in the high-position should be maintained,and moreover the edge and bottom water conings must be slowed down.The production of the single well was managed to ensure the three stabilities:"gas production,pressure and water production"and furthermore the rapid bottom water coning is avoided.The achievements showed that after the water control,gas production and reasonable production allocation implemented for Block D,the rapid encroachment by the edge and bottom waters was delayed,thus the gas production periods without the water were prolonged for the gas wells.
