  • Clay Fabric of Gassy Submarine Sediments
    Frontiers in Sedimentary Geology, 1991
    Co-Authors: Wen-an Chiou, William R. Bryant, Richard H. Bennett
    Abstract:

    The primary objective of this research was to delineate clay fabric microfeatures in sediment samples obtained by the use of a Pressure Core Barrel. A secondary objective was to evaluate the difference in clay fabric between Pressure Core Barrel samples and conventional Core samples, and to enhance the understanding of the clay fabric of fine-grained gassy sediments.

  • Application of submerged Pressure maintaining sealed coring techniques to Well Xushen-12
    Oil Drilling & Production Technology, 2007
    Co-Authors: Yang Yong-yan
    Abstract:

    The Pressure maintaining coring technique is a coring technique that can keep or be close to formation Pressure.It is of great significance to obtain complete and exact formation data by applying Pressure maintaining tools and sealing fluid,realizing the differential motion of outer cylinders at the bottom of wells,closing the ball valves of inner cylinders,sealing Cores in inner cylinders,preventing oil-gas-water losses from Cores during the process of coring,and then obtaining the Cores of original formation Pressure.In 2006,a new type of Pressure maintaining coring tool,BYM-III,suitable for Daqing deep layers,is developed and successfully applied to the deep layers of Well Xushen-12.In view of the characteristics of deep volcanic strata,the operation of one Pressure Core Barrel is successfully completed,based on using impregnated diamond coring bits,selecting assembly materials of ball valves,increasing protection structures for closing ball valves,improving sealing materials and forms,applying sealing fluid resisting high temperature,enhancing Pressure-filled technology,employing liquid nitrogen refrigeration technology,and optimizing drilling parameters.This provides abundant basic data and interpretation basis for having correct cognition of the geological conditions of the area,calculating gas reserves,and making reasonable development plans.

  • New downhole tools improve Core recovery
    Oil & Gas Journal, 1995
    Co-Authors: D.p. Huey, Storms
    Abstract:

    The need to analyze Cores at downhole conditions prompted the development of a series of Pressure Core Barrels, which can capture Cores without disturbing the sample through depressurization. In upper marine sediments, tungsten carbide insert roller cone bits tend to have life expectancies of several hundred rotating hours and thousands of meters of penetration. A bit can drill through hundreds of 10-m Core intervals before a pipe trip is required for a bit change. For time efficiency in coring operations in water depths averaging 3,000--5,000 m, both the Deep Sea Drilling Project (DSDP) and the Ocean Drilling Program (ODP) made a full commitment to wire line coring techniques wherever possible, thereby minimizing the number of pipe trips. The initial rotary Core Barrel became inadequate for the high quality of Cores desired for scientific analysis. The first new Core Barrel developed by DSDP to satisfy the increased scientific specifications was a wire line-retrievable Pressure Core Barrel. The paper describes this Pressure Core Barrel, as well as a Pressure Core sampler, hydraulic piston Corer, advanced piston Corer, extended Core Barrel, motor-driven Core Barrel, Core catchers, coring mud motor, and a diamond coring system.
