摘要：

针对东胜气田盒1段底水气藏压裂裂缝易沟通下部水层,导致底水快速锥进,水淹气井后无产能,有效建产难度大的技术瓶颈。将遇水固结型支撑剂和二次加砂压裂技术结合应用,在压裂缝底部形成人工遮挡层,在控制裂缝高度的同时有效阻挡气水界面上升,提高气水渗透率比率,降低裂缝内水流阻力,延缓气井见水周期,实现致密低渗底水气藏经济有效开发。控水二次加砂压裂技术东胜气田盒1段底水气藏累计试验应用10口井,施工有效率达90 %,相比邻井常规压裂工艺产气量提高60 %,液气比降低31.7 %,其中JP58-A井测试无阻流量达20.4×10⁴ m³/d,在实现压裂增产的同时取得较好控水效果。

Abstract:

He-1 reservoir of Dongsheng Gas Field is a bottom water gas reservoir. Fractures are easy to communicate with the bottom water layer, resulting in rapid bottom water coning and there is no productivity after water flooding of gas wells. It is difficult to get effective production. Combined the research and development of water-consolidated proppant with the secondary sanding and high-pressure fracture control technology, the artificial shelter layer is formed at the bottom of the fracture, which effectively prevents the rise of gas-water interface while controlling the fracture height, improves the gas-water permeability ratio, reduces the flow resistance in the fracture, delays the water breakthrough cycle of gas wells, and realizes the economic and effective development of tight low permeability bottom water gas reservoirs. The water-contorl secondary sanding fracturing technology has been applied in ten wells of the bottom water gas reservoir in He-1 Member of Dongsheng Gas Field. The construction efficiency is 90 %. Compared with the adjacent wells fractured by the conventional means, the water production of the application wells is increased by 60 %, the liquid-gas ratio is decreased by 31.7 %, and the measured open flow capacity of Well-JP58-A is 20.4×10⁴ m³/d, which has achieved good water control effect while increase fracturing production.

Key words: secondary sanding, water-control fracturing, water-consolidated proppant, shelter layer, Dongsheng Gas Field
