Abstract: Shengli Oilfield has abundant low-permeability tight oil resources with various types, dominated by glutenite, turbidite and beachbar sandstone reservoirs, showing complex characteristics and leading to great challenges in improving the speed and efficiency. Therefore, it is urgent to establish a large-scale and beneficial capacity construction mode with the integration of geology and engineering. By innovating working concept, operation mechanism and key technologies, and focusing on the technical bottlenecks and cross integration points of various disciplines, Shengli Oilfield conducted multi-disciplinary collaborative research on the integration of geophysics, geology, oil reservoir and engineering, consolidated the basic comprehensive geological study, strengthened the integration of multiple disciplines, and built an integrated collaborative decision support platform. The pre drilling prediction, while-drilling monitoring and post drilling evaluation were combined to develop geology and engineering integration technology for the whole process of scheme optimization design and implementation, which supported to realize the integration of concept, responsibility, process, operation, technology and platform, and achieve the purpose of improving accuracy, timeliness, and capacity while reducing barrel oil cost. The geology and engineering integration technology enabled to realize the effective utilization of untapped reserves with various oil reservoir types. The dynamic updating of high-precision integrated oil reservoir model and the construction of multi-disciplinary collaborative decision support system are the keys to the sustainable development of geology and engineering integration.
