Well Cementation For High-Pressure Adjustment Well In Duanliubo Block Of Dagang

Duanliubo Block In Dagang Oilfield Was Developed In The Late 1970s, And Belongs To Lithologic-Structural Oil Deposit. The Oil Deposit Geology Is Complex Structurally, Characterized By Great Lithologic Changing, Deeply Buried Deposit And Serious Reservoir Stratum Heterogeneity, Especially With Low Oil Deposit Permeability. After Years Of Injection-Production Operation, The Original Oil-Water Pressure System Of The Block Target Stratum Has Been Damaged, And Abnormal High And Low Pressure Areas Appear On The Plane Inside The Stratum And Between Stratums. Over The Years, The Cementing Quality In This Block Has Plagued Many Enterprises Specialized In Oil Production, Well Drilling And Cementing. The Development Is A Major Problem In This Block, And It Is Difficult To Be Effectively Addressed. This Problem Is A Technical Bottleneck For The Development Of Adjustment Well In Domestic Oilfields, Further, There Is No Mature Technical Measures And Successful Cases In International Industry.

In The Second Half Year Of 2014, The 3rd Oil Production Factory Of Dagang Oilfield, Southwest Petroleum University And Chengdu OMAX Oilfield Technology Co., Ltd., Working With Specialized Institutions And Service Enterprises, Overcame Difficulties. From Attempting Difficulties, Understanding Difficulties To Solving Difficulties, 16 Exploratory Wells In Total Are Involved, Including 15 High Quality Wells, With Quality Rate Up To 93.75%, The Poor Cementing Quality For More Than 30 Years In This Block Are Successfully Solved, And The Technical Specifications For “Cementing At Ultra-High Pressure For High-Pressure Adjustment Well” Are Established.

On August, 2015, The Scientific Project In Duanliubo Block Of Dagang Oilfield Was Successfully Accepted By The 3rd Oil Production Factory Of Dagang Oilfield With The Witness Of Engineering Technology Division Of Dagang Oilfield, Petroleum Engineering Research Institute Of Dagang Oilfield Company, Dagang Oilfield Drilling & Production Institute, Information Technology Division Of Dagang Oilfield, Southwest Petroleum University And Chengdu OMAX Oilfield Technology Co., Ltd. The Success Of This Project Not Only Extends The Life Cycle Of Water Injection Adjustment Wells In Old Blocks Of Old Oilfields, But Also Finds A Way Of Developing Potentials, Increasing And Stabilizing Production For Adjustment Well In Old Blocks, And Sets A Successful Example For The Well Cementation Of International Adjustment Wells. The Project Not Only Means The Improvement Of "Production - Learning - Research" Practice Base To Cultivate Talents For Society, Formed By Chengdu OMAX Oilfield Technology Co., Ltd. And Southwest Petroleum University, But Also Reflects The Purpose Of OMAX Oilfield Technology Co., Ltd. It Is Because OMAX Oilfield Technology Co., Ltd. Has Challenge Concept, The Company Is Able To Attain A New Height, And Ranks The Top Of Cementing Industry.
