Abstract: There is a series of problems in the L oil area in the eastern part of the South China Sea, such as few large and medium-size oil and gas fields discovered, production declining rapidly in old oilfields, discovered marginal oilfields difficult to be brought under production, and inadequacy in replaced reserves. The multi-dimensional integration principle based on the innovative mindset is developed in settlement of those above-mentioned problems. The multi-dimensional integration based on high-grade geological oil reservoir study, including integration of big data information and technology, integration of exploration, development, production and engineering, and integration of regional and overall research, is focused on highefficiency operation of value investment. Exploration-development integration is helpful to accelerate development process of the marginal oilfields in the L oil area in the eastern part of the South China Sea, promoting the progressive exploration of the surrounding areas and locating the new growth point of replaced reserves for sustainable production. Five marginal oilfields under evaluation come under the basic design stage. With the contributable producing reserves accumulated to surpass 5000?04m3, the accumulated oil production is predicted to exceed 1000?04m3.
