Novel Chemically Bonded Phosphate Ceramic Borehole ：新的化学键合的磷酸盐陶瓷钻孔

1、Novel Chemically Bonded Phosphate Ceramic Borehole Sealants for Arctic EnvironmentDE-FC26-01NT41248ProgramThe project was selected under a non-competitive five-year cooperative agreement with the University of Alaska Fairbanks (UAF) to conduct arctic energy research in two broad categories: fossil e

2、nergy and remote electrical power generation. The DOE Arctic Energy Office and UAF are collaborating with the energy industry and state agencies to better identify Alaskas unique research needs. Project GoalThe goal of the project was the development of novel ceramic borehole cement with suitable in

4、 Ceramic borehole cement developed at ANL, which holds potential as a suitable insulating cement for use in permafrost regions. BenefitsThe phosphate ceramic borehole cement developed and tested by ANL and UAF will significantly improve oil and gas operations in the Arctic by helping to control gas

5、migration. The new cement protects the permafrost soils, and provides improved wellbore transport of hydrocarbons. The light weight cement will be more cost effective and efficient for Arctic operators to use and transport to remote locations. Additionally this material holds tremendous potential in

6、 assisting in the development of shallow viscous oil and gas hydrates in the arctic by protecting the permafrost in these shallow wells.BackgroundOne of the basic material requirements in exploration and completion operations in permafrost regions is a suitable insulating cement that will keep the p

7、ermafrost frozen and undisturbed during production and transport of oil and gas. A ceramic borehole cement developed at Argonne National Lab (ANL) may fulfill this need. ANL in partnership with the University of Alaska will tailor this cement for permafrost regions and demonstrate its application in

8、 Alaska. The lighter weight of this product might help make wells in remote locations more economic by reducing transportation costs associated with transporting the material to potential worksites.Project SummaryProject objectives include: 1) formulate and optimize the ceramic borehole cement for u

9、se in permafrost regions, 2) Conduct simulated laboratory tests at UAF, 3) Collaborate with industrial partners and conduct field tests under arctic conditions at a site in Alaska, 4) Test the formulations for other applications in the infrastructure development of Alaska. Annular gas migration duri

10、ng cementing oil and/or gas wells is a serious problem. Failing to control gas migration can result in gas channeling and costly squeeze jobs. One of the basic material requirements in oil and gas exploration and completions operations in permafrost region is suitable insulating cement that will kee

11、p the permafrost region undisturbed during production and transport of oil and gas. New types of cementing approach could help reduce the safety and environmental hazards created by cementing failures. A Phosphate Bonded Ceramic borehole cement developed at ANL may fulfill this need. The University

12、of Alaska is working with this new material to develop an appropriate "blend" to meet the oil industries needs. The project is nearing completion of it's first years work and has made significant strides including identifying the mix of material to produce properties required for North

13、 Slope downhole pumping while meeting required tensile strengths. Work currently is being done to determine the materials reaction to thaw-freeze cycling and whether the material will set at temperatures as low as -40 F. This work is being done in the UAF Cold Room. In addition to the testing work,

14、UAF Graduate Student Sudiptya Banerjee won the 3rd place award at the 2005 Society of Petroleum Engineers (SPE) Western Region Meeting in Irvine, CA, in the M.S. Division for his paper, "Novel Chemically Bonded Phosphate Ceramic Borehole Sealants for the Arctic". A week later, Mr. Banerjee

15、 won the first place gold medal (Sandy Purdy Research Excellence) at the American Association of Drilling Engineers (AADE) conference in Houston, TX. Current StatusWork is proceeding on schedule with the intent to move into field testing later this year.Other Government Agencies: Argonne National LaboratoryProject Start: September 29, 2004Project End: September 30, 2006DOE Contribution: $351,056Performer Contribution: $426,326 (55%
