鄂尔多斯盆地天环坳陷南端固井技术研究

2003年开始,华北分公司以探索中生界延长组和延安组石油为主要目标,在延长组和延安组见良好油气显示,多口井在多个层位试获工业油流。2012年进入大开发阶段,该地区地层承压能力低,固井易漏失,固井质量受到严重影响。基于该种情况经过一年的理论研究和现场实践总结出了适合本地区固井施工的一系列措施,固井质量优良,有效的减少了该地区固井漏失情况的发生。

Research on the Cementing Technology for The Southern End of Tianhuan Depression,Ordos Basin

Beginning in 2003, Sinopec North China Branch explored petroleum in Mesozoic Yanchang Formation and Yanan Formation, explored results was good, many wells tested in multiple layers obtained industrial oil output. In large-scale development after 2012, because of low ground bearing capacity and easy cementing leakage in the area, cementing quality was severely affected. Based on the case, a~er a year of theoretical research and on-site practice, a series of cementing measures for the region were summed up, good cementing quality was obtained.
