Zaoyuan Oilfield Complex Fault Block Oil Reservoir Characteristics Of Low Mobility And Stability Measures

Degree of complex fault block oil reservoir flow characteristics and stable measures of the development phase in the oil field although related to, but not universal, and no mature technology series, especially for low-flow test reservoir structure, reservoir fluid, the remaining Oil Distribution and Stability of measures such as the system does not need more in-depth research to meet the needs of the current development stage.Paper production line to serve the purpose of scientific research, through the full research and demonstration to Zaoyuan Oilfield. The oil reservoir flow test for Zaoyuan low, complex structure, reservoir heterogeneity, etc., oilfield water flooding the low degree of control, interlayer contradiction, poor level of reserves used and short development of conflict situations, from micro-reservoir structure, mobility, flow unit and remaining oil sectors, to carry out a more systematic theory and practice. Seismic interpretation technology through the application of fine microstructure studied oil;theory with practice basis, the degree of reservoir mobility reclassified, revealing a well flow productive capacity and the linear relationship; and in-depth sand flow units conduct research, anatomy of four different types of flow units and production relations. In the above case studies based on the use of geological and reservoir methods such as comprehensive analysis of remaining oil potential area, revealing the remaining oil in the plane and the vertical distribution law, through the deployment of new wells, fill holes, transfer note, sub-injection and other conventional measures to tapping the potential remaining oil potential, focus is to take "strong points, weak side, to move the plane steady, phased injection, single well stimulation" and stable targeted measures, from all fields of governance within the context of large-scale work for the oil-term Stability on production conditions.This thesis work has achieved fruitful results, which highlighted are: 1, the total of the six types of Microstructure, number 52. 2, reservoir flow was re-classified, so that theory more in line with actual production needs classification. 3, carried out high-precision single-sand flow unit division, is divided into four categories. 4, application of geological analysis, reservoir engineering and modeling are three methods, comprehensive study of the low mobility of residual oil rich areas.Comfortable and practical Zaoyuan oil fields, after adjustment, a significant increase in recoverable reserves of oil, water flooding effect significantly improved the overall development level of the three types of oil rose to a class. And summarizes a set of low mobility complex fault block oil reservoir to improve secondary recovery ratio is more stable measures appropriate for the level of such reservoir to improve the development provides a cost-effective method.
