Abstract

Abstract: In recent years, as newly-discovered oil and gas resources become more and more inferior while old oil fields in China enter into the middle-later development stages, great challenges emerge to the exploration and development. Under this circumstance, new ideas, techniques and practices are urgently needed to solve these problems. Successful large-scale development of unconventional resources in the United States has significantly promoted the integrated innovation and development which combines multiple disciplines and multiple technologies. Accordingly, the geology-engineering integration is proposed in response to the challenges induced by current low oil price and the basic requirement of “profitable exploration and development”. This model represents a new way to realize profitable exploration and development of oil and gas fields (especially the unconventional and complex oil and gas fields) in China. The organization idea and operation pattern of such geology-engineering integration have been successfully applied in developing low-porosity and low-permeability reservoirs in the Kuqa area of the Tarim Basin in western China, the Sichuan Basin (marine shale gas), and central-eastern China. This paper described the concept, connotation, and applicable scope of the geology-engineering integration, and presented three prerequisites for implementing this model. Moreover, some suggestions were put forward for promoting the development of the geology-engineering integration. To be specific, in addition to expanding the application scope and scale, learning curve should be established to develop more pertinent technologies. Innovation should be made in management model of geology-engineering integration, and market-based and cross-enterprise coordination should be applied beyond traditional systems to integrate the advantages of technologies. In this way, it is expected to substantially enhance production and profitability of complex reservoirs in China.

Key words: geology-engineering integration, complex reservoir, shale gas, tight oil, practice, innovation in management model
