Development and Application of a Leakproof Stage Cementing Collar with Packer in the Shunbei Oil & Gas Field

摘要:
顺北油气田二叠系固井极易发生漏失，环空水泥缺失长度超过2 000 m，导致生产期间套损严重。针对该问题，研制了封隔式分级箍，并进行了室内性能评价试验和现场应用。室内性能评价试验发现，该分级箍不仅具有常规分级箍的功能，还可以在一级固井后胀封封隔器，封隔漏层，防止二级固井时发生漏失，提高环空水泥环完整性；封隔器胀封后，环空封隔能力可达20 MPa；循环孔关闭后，管内密封能力不低于套管抗内压强度。顺北油气田9口井应用了封隔式分级箍，二级固井平均漏失量由105.1 m3降至3.5 m3，环空水泥缺失长度由2 048 m缩短至350 m，节约固井成本约1 100万元。封隔式分级箍解决了长裸眼易漏失井段固井时的漏失问题，为顺北油气田的高效开发提供了技术支撑。
Abstract:Permian cementing was leakprone in the Shunbei Oil & Gas Field, and the loss of annular cement surpassed 2 000 m, which led to severe casing damage in the production period. To solve this problem, a stage cementing collar with packer was developed, performance evaluated in the laboratory, and applied in fields. The tool works well not only with the conventional function of the stage cementing collar, it can also expand the packer upon the first-stage cementing to seal the layers and prevent the leakage of the second-stage cementing and thus improve the integrity of annular cement sheaths. After the expansion, the annular sealing capacity of the tool could reach 20 MPa, and when the circulation holes were closed, the internal sealing capacity should not be lower than the internal pressure strength of the casing. The developed tool was applied in nine wells of the Shunbei Oil & Gas Field. The results revealed that the average leakage of the second-stage cementing was reduced from 105.1 m3 to 3.5 m3, and the missing length of annular cement declined from 2 048 m to 350 m, saving about 11.0 million yuan in cementing. The stage cementing collar with packer could solve the leakage problem in the cementing of the leakprone well sections which tend to leak in long open holes. The lessons learned in this study provide technical support for the efficient development of the Shunbei Oil & Gas Field.
