摘要:
四川盆地太阳背斜叙永区块地质复杂,页岩气储层龙马溪组、五峰组有机孔与微裂隙发育,富气页岩段含气量高,气层压力系数总体为1.2~1.6,处于弱超压状态。漏失与气层同层,固井压稳与防漏难度大;水平段长,位垂比大,套管居中、顶替效率不易保证;泥浆驱替困难,影响界面胶结或导致出现微间隙;分段强化压裂要求水泥石须具有良好的韧性。针对上述固井难点,通过研发弹性水泥浆体系和高效冲洗加重隔离液体系,结合浆柱结构设计、防漏压稳、提高顶替效率、预应力等固井工艺措施,形成了一套适用于该区块的浅层页岩气水平井固井技术,并进行现场应用11井次,为同类井固井提供了经验。
Abstract:
Xuyong block of the Taiyang anticline in Sichuan Basin has complicated geology. Organic pores and micro-fractures have developed in the shale gas reservoirs of the Longmaxi and Wufeng Formations,and the gas-rich shale section has a high gas content. The pressure coefficient of the gas layer is usually from 1.2 to 1.6,and it is in a weak overpressure state. The leakage is in the same layer as the gas layer,making it difficult to stabilize the cementing pressure and prevent leakage;long horizontal sections and high vertical ratios make it difficult to ensure casing centering and replacement efficiency;mud displacement is challenging,influencing interface cementation or generating microgaps,and staged enhanced fracturing requires tougher cement stone. A set of cementing techniques for shallow shale gas horizontal wells suitable for this block has been formed through research and development of elastic cement slurry system and high-efficiency flushing and aggravating isolation fluid system,combined with cementing process measures such as slurry column structure design,leakage prevention,and pressure stabilization,improving displacement efficiency,and prestressing,etc. This technology has been applied in 11 well times,providing experiences for the cementing of similar wells.
