Work Detail

Construction Work For Water Projects – Utilization Of Geothermal Energy Development 3.. 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 Distant Hydrocarbon Research Borehole Drilled And Closed In The 1990S Into A Thermal Well. We Want To Connect The Thermal Water Heat Source, Forecasted For A Yield Of ~ 700 [Liters/Minute] And ~57 °C, To The Heat Center In The Thermal Bath, And Connect It To A Newly Developed 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 With 24 Shots Per Meter At Their Actual Level: 815 - 820 M, 956 - 967 M, 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 Construction The Tenderer Wishes To Carry Out The Procedure In Accordance With Section 98 (3) Of The Invitation To Tender: Stage 2 Of Well Preparation And Well Preparation The Temporary Cooling Pond Is Expected To Be Filled With Sand After Measuring The Water Flow And Cleaning The Base, The 102 Mm Diameter Steel Insert Filter Must Be Installed In The Above Depths With A Johnson Filter With A Gap Of 0.4 Mm, From 780 M To The Base, 1071 M. The Annular Space Around It Must Be Filled With Graded Gravel, Expected To Be 1-3 Mm In Diameter, And Then The Pipe Gap Seal Accurately With A 102/7” Diameter Gland. Cleaning With A Compressor Should Be Performed Again, Followed By Test Pumping, With A Log Of Operating Parameters Every 2 Hours. In The Meantime, The Following Instrumented Well Tests Must Be Performed: - Base 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 Provided In The Relevant Regulations No
