Integrated Application of Mud Logging, Elements and Geosteering in Horizontal Wells-Example of the Weiyuan Shale Gas a Well in the Sichuan Basin

Abstract

: The horizontal section of the horizontal well is drilled to a certain length in the target, which increases the exposed area of the oil and gas reservoir. The basic purpose of the horizontal well is to increase oil and gas production or oil and gas recovery. With the development of Weiyuan shale gas horizontal wells, the development of drilling technology and the demand for higher precision formation analysis, as well as the demand of oil field companies to improve quality, efficiency and cost, the integration of various professional models has mushroomed. Several aspects, geological guidance based on petroleum geology, as well as practical applications, characteristics, and mud logging relationships are summarized. The cooperation of the three factors improves the comprehensive technical ability and production and management efficiency of the field geology.
