Geologic Characteristic And Development Principle In Du 84th Block Of Raoyanghe Oilfield

Outlined in this article sheds some light on the status of the development of super heavy oil field. From structural characteristics, sedimentary characteristics, reservoir characteristics, fluid properties, water distribution, formation pressure and temperature, etc. details of around 84 DU Raoyanghe reservoir geological features and ultra-heavy "four-high and one low," the special physical properties. Through the enormous amount of statistical data, the block development of the characteristics of vertical wells and horizontal wells in the laws of the system throughput studies and geological parameters from the reservoir, the steam injection process parameters, such as perforation thickness analysis of the effect of the impact of oil throughput constraints factors, the throughput for the follow-up wells to provide a scientific basis. Throughput process for the existence of a short production cycle, the low rate of extraction of water, sand, steam channeling, uneven layers used to carry out a detailed analysis of other reasons, the scene at the same time block the production of the close combination of the actual reserves of unspent deepening regional geological studies, the use of wells indirectly, for the inter-layer, multi-well technology to increase the overall throughput, such as the use of the degree of reservoir, production decline slowed down, and strengthen the production of dynamic tracking and optimization of numerical simulation studies, the production of injection and production parameters to achieve reasonable and clear rules of handling and speed up the latter part of super heavy oil through put capacity pilot test technology to succeed. Field application results show that the dawn of the study of super heavy oil field development has a positive role in guiding, steam-assisted gravity oil spills (SAGD) technology suitable for around 84 Raoyanghe Du reservoir development.
