Well Yuanlu 176 Makes New Achievements In Technical Services Of 2.55 Ultra-High
Southern Exploration Branch, Sinopec Carried Out 139.7mm Tail Gas Hanging Ultra-High Density Cementing Operation In Well Yuanlu 176 Of Yuanba Under The Cooperation Of Chengdu OMAX Oilfield Technology Co., Ltd. And Zhongyuan Cementing Company, The Smooth And Safe Construction Of This Project Was Commenced On June 12, 2015. The Density Of Cement Slurry Of This Well Reached 2.55-2.60 G/Cm3, Hitting The Record Of Yuanba Region. The Cementing Quality Of Cement Bond Logging (CBL) And Variable Density Logging (VDL) Are Excellent. Party A Gave Full Affirmation And High Praise For The Excellent Cementing Quality.
The Slurry Density Of This Well Reached 2.40g/Cm3, And Leakage And Cement Gas Cut Occurred Repeatedly Before Cementing. The Insufficient Leakage Return Height Is Easy To Result In Gas Channeling During Cementation, Or Instable Pressure After Cementation Results In Bad Cementing Quality. Leaders Of The Company And The Project Management Department Pay High Attention To This Superior Difficult Cementing, Carefully Develop Proposals, Refine And Quantize All Cementing Operations. The Idiosome Anti-Channeling Cement Slurry System Featured By Strong Anti-Channeling, Good Fluidity And High Strength Is Adopted During Construction. The Elastoplastic Adhesive (Patented Products Of OMAX) Is Used To Make The Cement After Solidification Have Good Elasticity And Maintain Long-Term Sealing Performance, And To Ensure The Smooth Mining At Later Stage.
The 2.50g/Cm3 Cement Slurry Is Used During The Construction, And Increased To 2.55-2.60g/Cm3 As Tail Slurry By Cement Truck, Which Reflects The Unique Advantages Of OMAX’s High Density Cement Slurry System In Preparing High Density Cement Slurry And Simplifies The Process Of Construction On The Ground. The Continuous Success Of High Density Cementing Operation For This Well And Previous Wells Further Strengthen The Leading Position Of OMAX In High Difficult And Complex Cementing Operation, And Shows The Good Prospects Of OMAX.
