A management mode of technological and economical integration for natural-gas development in Sichuan Basin
Rich in natural-gas resources,Sichuan Basin where above 2×1012 m3 of the proved reserves in place had been submitted cumulatively from 2019 to 2023 is one of the most abundant areas in China,which makes the development of natural gas access to the critical era of high quality.Nowadays,shifting to deep or ultra-deep targets,our exploration on conventional gas calls upon advanced drilling and completion technologies as well as better investment guarantee.And for tight gas,with strong heterogeneity in its reservoirs and numerous reservoir types,it's also urgent to upgrade low-cost matching technologies.In addition,as an emerging unconventional energy,shale gas will evolve into an elemental alterna-tive domain for the coming large-scale reserve and production increase.So,confronted with ever-growing hardships in in-vestment control,a management mode of technological and economic integration was discussed to address several issues throughout the natural-gas development and management in this basin,such as investment and unequal benefits,technolo-gy and disconcordant economy,and follow-up tracing and adjustment.Results show that(i)linking the entire integration process,a three-level management system is constructed to accomplish closed-loop control across all life cycle;(ⅱ)man-agement is the integration pivot.Employed the three-stage workflow and the five-point closed-loop means,a sort of work environment is set up for the integration to maximize economic profits;and(ⅲ)intensifying organization security,consum-mating necessary system,fostering talents and building up intelligentization platforms will make the integration come true.It's concluded that,with the brand development of natural gas in Sichuan Basin,this discussion on the management mode of technological and economic integration may provide not only guidance for the cost control in natural-gas development and optimum benefits but reference for both development and management in some other oil and gasfields.
