Casing Detection Technology In Zhongyuan Oil Field

Zhongyuan Oilfield has been the development of the oil field in the late, and because of deeply buried reservoirs, block groups are very active, temperature, pressure, high salinity of the time of formation water corrosion, as well as the oil wells were fracturing, acidizing Perforating and measures such as oil wells causing serious damage to the casing, there has been corrosion perforation, deformation, even faults situation. The urgent need for effective detection of casing means of identifying the reasons, and to take measures to repair, oil wells resume normal production. According to the actual situation of Zhongyuan Oilfield, the casing of the current testing technology, in this thesis research.In this paper casing detection technology in the Zhongyuan Oil Field, and improve the matching and the corresponding interpretation. These detection technologies, including the 18-arm caliper logging imaging technology, corrosion perforation of the casing for leakage WLT, CAST-V ring hole sonic imaging logging technology, vertical logging technology. CAST-V casing detection imaging technology is more advanced international monitoring technology casing, the casing can be precisely calculated the diameter, wall thickness, diameter, the better the casing deformation, wear, corrosion, perforation, and the location of cracks test, the technical condition of the casing to make accurate assessment. In the promotion of vertical logging process, amended the vertical log interpretation drawing board to improve the quantitative interpretation methods to improve the accuracy of quantitative interpretation of the use of the vertical log data on the bridge of the oil wells in oil fields mouth to block the overall monitoring, Corrosion perforation of the casing found position taken casing repair technology, resumed production and reduce the aquifer, an increase of production capacity. Application of 18 in the promotion arm caliper logging imaging technology in the process, improve the image of 18-arm caliper logging tools structure; logging on the spot software and data interpretation software has been upgraded; improved logging data interpretation; formulated a 18-arm caliper imaging logging site inspection and data processing and interpretation standards; use 18 arm caliper imaging logging, in the overhaul of the old wells, sidetracking before casing drilling technology evaluation of the situation, to guide the elderly Well overhaul, sidetracking drilling programme. Flowmeter casing corrosion perforation for leakage logging technology can pinpoint leakage water shutoff position taken measures to not only improve waterflood development results, driven by increased water reserves, but also can reduce invalid injection. Also through the launching of corrosion perforation logging, has been greatly reduced on the surface and underground pollution, mainly to ensure that normal water injection wells, the wells by the corresponding effect for a stable oil output of crude oil production played a role. In the promotion of applications, the project is also supporting the casing for leakage Logging Technology, developed a standard logging data processing and interpretation, prepared at the scene logging data quality control requirements.CAST-V through casing imaging detection technology, vertical WLT, 18 arm caliper logging imaging technology portfolio and find leakage flowmeter logging in the popularization and application of Zhongyuan Oilfield, understanding of oil, gas and Casing technology situation, find out the casing corrosion, deformation, faults, perforation of the well location, taken-for-sets, subsidies, such as blocking card casing repair measures to promptly resume oil, gas, and the normal production wells for the development and production of oil play active role. Casing technology portfolio monitoring the conduct of a very substantial economic and social benefits significantly.
