TH1471A - Improvement of drilling muds, replacement processes - Google Patents

Abstract

Improved replacement process for removal of drilling sludge (Solids and oil) out of the borehole rather to Deliver brine used in the production well And used to block the floor Produced without solids Clean water will circulate in the pit system. Drill to eliminate and blow out the mud used in drilling Mainly enriched with water by mixing a surfactant and alcohol in the water. Transport used muddy water In drilling out of the borehole system without circulating rhythm The prepared water will continue to circulate within the borehole system to Receive the brine until the drilling mud is completely transported. By the flavored water that circulates, and again by Not interrupting the flow It was replaced with clean, solid water and was expelled. And the appropriate disposal site. Finally, clean water free from solids is expelled and replaced with water. Solid free salt

Claims (5)

1. It is a process for removing solids and oils from slurry used in drilling out of borehole systems before adding salt without any material. The hardening fluid is used as well as the wellhead fluid and the fluid used to block the production layer. Drilling from the borehole system by circulating clean water in its place. The drilling mud was used until most of the mud was removed. (B) The water quality was added by adding a surfactant and alcohol to the clean water and stirring and stirring. Mix the said flavored water at high speed in the well tool. Drilling on the ground (c) circulating the flavored water through the machine Hand on the drill rig to remove clean water that carries the drilling mud and circulate the modified water into the borehole system. There will be salt water in the well and the brine used to block it. Soil inflow Do this until the muddy water used to Most piercings are cheap. (D) Remove the perforated containing the drilling mud suspended from the Borehole systems to the appropriate disposal site with clean water From solids without interrupting circulation through the borehole system and (e) removing the clean water of the process (d) from the section of the borehole system where Obtain salt from an external source of the borehole with brine used in Blocking of solids-free layers 2. Process of Claim 1. Clean water may be sea water. Or fresh water that is relatively free of solids. 3. Process of the 1st tool on the rig. The flavored water circulates through both the borehole and ring tubes. Inside of the borehole and including various leakproof guards And other tools Related to the tool on the drilling rig. 4. Process of the 1st property of the tool on the ground water. The flavored material circulates through the ground tools, including the pump, container, material discharge valve. Water cleaning machine Mud sieve shale shale 5. PROCESS OF PROPERTY 1 Tool on drilling rig The pipe is drawn up and down inside the borehole and the pipe is rotated as Occasionally to aid in the suspension of drilling muds in Processed water circulates. 6. Process of claim 5: drawing up and down holes. Within about 30 feet of borehole. 7. Process of Clause 5 with surfactant. And some alcohol is mixed in clean water to produce water that has been Make the quality before dragging the pipe up and down holes and turning. And after To add the surfactant and the rest of the alcohol to the water This way, the final water quality is added. That circulates through the borehole system. 8. Process of Claim No. 1 Add surfactant and Less than 1% of each type of alcohol is added to clean water for producing quality water. 9. Process of the 1st qualification. Heavy molecules in the range of about 150 to 500, which feature Mostly hydrophobic and select surfactants from the group. Containing Aliphatic amine amide And aliphatic aman Oxides in which amines and amides are alkyl groups that have atomic number of Carbon between 8 and 18 atoms and alcohol are aliphatic. Alcohols with a carbon atom number of between 5 and 8, 10 process of matter 1, where surfactants are bishydroxyethylsethyl amines and alcohols are hessanol 1. 1. Process for solids and oil removal of the mud used. For drilling out of borehole systems before brine delivery are used in boreholes. And brine used to block solid-free layers The procedure consists of 11.1 removal of drilling mud from Borehole system by circulating clean water until the mud used in Much of the production exits the borehole system and blows it out into clean water. 11.2 Adjust the water quality by adding a surfactant and alcohol to the clean water and stirring and mixing the quality modified water. At high speeds in the ground instruments of the borehole systems, these surfactants have a molecular weight in the range from approximately 150 to approximately 500, which feature as a part of the hydrophobic. And the aforementioned skin reducing agents were selected from the group It is composed of aliphatic amine amide and alpha-tic amine oxide, in which amines and amides have an alkyl group with atomic number. Of carbon between 8 and 18 atoms and the alcohol mentioned herein is the aliphatic Alcohols with carbon atoms between 5 and 8 atoms 1.3 circulate the refined water through floor tools. Soil and tools on the borehole system to replace Clean water to carry drilling fluid After that circulate Water that is enriched in the borehole system with brine used in Brine wells used to block production until most of the drilling mud was drained in the circulating quality modified flotation arm. 11.4 Eliminate the modified water carrying the mud It is used for drilling from borehole systems to suitable disposal sites with clean, solid water without interrupting operation. Circulate the borehole and 11.5 remove the clean water of step 11.4 from the section of the borehole system that receives brine from an external source of Brine borehole systems used in wellhead and brine used to block solid-free layers 1 2. Process of claim 11: up and down the drill pipe And spins occasionally in the bore during circulating water that is Add quality to help in removing the muddy water used in the Drill out of tools on drill stand 1 3. PROCESS OF PROPERTY 12, ADDING OF THE STRESSURE Skin and some alcohol before pulling the pipe up, down, swirling and turning And after that add the rest to the water that has been enriched with quality 1 4.Process of claim 11 Adding surfactant And approximately 1% less of each type of alcohol to clean water for producing high-quality flavored water 1 5.Process of claim 11, Surfactants are bishydroxyethylsethylamine and alcohol as hexanol (Clause 15, 4 pages, 1 figure).
