摘要:
針對大慶油田喇嘛甸儲氣庫未開展過井筒技術檢測和安全評估、套管柱存在安全使用風險的問題,開展了套管柱測井檢測實踐和安全評估技術研究,優選測井檢測技術,進行現場檢測實踐,運用統計學分析原理對套管壁厚解釋結果進行對比分析,探索低成本高精度測量井下套管柱損傷情況的有效途徑,并在此基礎上對儲氣庫井套管柱的剩余強度進行力學分析,評估套管柱的安全使用狀況。通過17口井的測井檢測實踐,結果表明:所有被檢測井均未出現嚴重腐蝕、穿孔、變形等狀況,在多種起油管檢測技術的組合檢測下,能較為直觀的反應套管柱的壁厚減薄、腐蝕等現狀,
Abstract:
Aiming at the problem that the Lamadian Gas Storage in Daqing Oilfield has not carried out wellbore detection and safety assessment, and that the casing string has safety risk, the casing string logging detection practice and safety assessment technology are studied. Logging detection technology was optimized and field testing practice was carried out. The interpretation results of casing strength are compared and analyzed by using statistical analysis principle, and an effective way to measure the damage of downhole casing string with low cost and high precision is explored. On this basis, the residual strength of casing string in gas storage wells is analyzed mechanically, and the safe operation status of casing string is evaluated. Through logging testing practice in 17 wells, the results show that no serious corrosion, perforation and deformation occur in all tested wells. Under the combined detection of various tubing detection techniques, the present situation of casing string wall thickness thinning and corrosion can be more intuitively reflected, but the accuracy of tubing detection technology in casing wall thickness interpretation is not sufficient. The residual strength of casing string is calculated and analyzed. The safety factors of minimum internal pressure and the minimum collapse pressure resistance are 1.50 and 1.46 respectively, which are higher than the selection and design standards of injection and production string in gas storage. The casing string is safe in use.
