Tenders Are Invited For Construction Work – Utilization Of Geothermal Energy Development 2. in Hungary

Work Detail

Construction Work – Utilization Of Geothermal Energy Development 2.. The Municipality Of Mezőcsát Wants To Ensure The Heating Of The Towns Public Institutions With Geothermal Energy. For This Purpose, They Would Use The Barren Hydrocarbon Research Borehole Marked Mezőcsá - 1 On The Border Of The Settlement. As Part Of The Project, In The Northern Border Of The Settlement, Approx. We Are Planning To Convert A 600 M Distance, Barren Research Well For Hydrocarbons Drilled And Sealed In The 90S, Into A Thermal Well. The Thermal Water Heat Source, Forecasted For A Yield Of ~700 [Liters/Minute] And ~57 °C, Will Be Led To The Thermal Center In The Thermal Bath And Connected To A Newly Constructed District Heating System, Which Will Partially Replace The Current Use Of Natural Gas For Heating The 13 Municipal Properties. Phase 1: Well Training: After The Drilling Equipment Has Been Deployed And Installed, The 3 Christmas Tree Mounted On The Well Must Be Dismantled, And A Blowout Preventer Must Be Built On The 9 5/8 Pipe Head. After That, The Exploratory Borehole Will Be Cleaned Up To 1071 M, I.E. Up To The Top Of The Cement Plug. The Depth Of The Layers Included In The Plan In The Original Geophysical Profile Must Be Specified Using Natural Gamma Profiling, And Then The Following Layers Must Be Opened In The 7 Casing Pipe In Their Actual Level, With 24 Shots Per Meter, Using Jet Perforation: Up To 815 - 820 M Up To 956 - 967 M Up To 971 - 976 M, 1020 - 1025 M, Up To 1067 M. The Drilling Is To Be Carried Out Gradually From The Bottom Up, Until The Maximum Sand-Free Performance Is Achieved. Based On The Results Obtained, The Construction Can Proceed To The Next Stage During The Execution Of The Well The Tenderer Wishes To Carry Out The Procedure In Accordance With Section 98 (3) Of The Act On Well Construction And Well Construction Phase 2 Of The Well Construction And Well Construction After Measuring The Water Flow And Cleaning The Base, A 102 Mm Diameter Steel Insert Filter Must Be Installed In The Above Depths With A Johnson Filter With A Gap Size Of 0.4 Mm, From 780 M To The Base, 1071 M. The Annular Space Around It Must Be Filled With Graded Gravel Of 1-3 Mm Diameter, And Then The Pipe Gap Seal Accurately With A 102/7” Diameter Gland. Cleaning With A Compressor Should Be Done Again, Followed By Test Pumping, With A Log Of Operating Parameters Every 2 Hours. In The Meantime, The Following Instrumented Well Tests Must Be Carried Out: - Footing Depth Control, - Rheometering, - Capacity Measurement, - Pressure Rise Measurement, - Pressure Gradient Measurement, - Water And Gas Sampling. The Sample Taken Must Be Transported To An Accredited Laboratory And Have A Complete Hot Water Test Performed. The Geological And Technical Data Of The Trained Heat Well Are Given In The Relevant Regulations No
