Diversified Fracturing Technology Research And Application In Xinglongtai Oil Production Plant

With the constant expansion of exploring range in Xinglongtai Oil Production Plant and with the constant deepening of reservoir geological Research and gradual changing of development object, the main types of oil and gas reservoir has deep buried hill oil, edge and bottom water reservoir, volcanic reservoirs, tight sandstone gas reservoirs and so on. The common characters of these areas are low pressure, low porosity, low permeability and low saturation, these characters badly hamper the effective development of economies. Because of the low naturalness productivity of single well, some fracturing transformation need be followed up. Subject to the existing technological level, the reservoir stimulation technologies need further investigation. Therefore, improving the existing technological level and exploring the deep undeveloped reservoir effectively has important significance on development of the mid-late field.The major objective of this thesis is to study Xinglongtai Oil Production plant. Based on the investigation of comprehensive literatures about the stimulation technology of such reservoir inside and abroad, through the indoor experiment and field application, we optimized fracturing fluid。We studied different fracturing fluid and fracturing technology system implementation for different types of reservoir. It includes high temperature fracturing fluid, fluid loss technology, rapid flowback technology and the new research of temporary plugging agent. Improve the comprehensive performance of fracturing fluid. According to different reservoir and reservoir conditions, has formed the one whole set perfect stimulation technology pattern.The article was departure from the horizontal well fracturing mechanism, through the integrated reservoir evaluation and optimization of fracture parameters, and the latter supporting technology research to improve the success rate of the construction of horizontal wells and fracturing effects. The above research achievement provides the guarantee to the renovation of low porosity and low permeability reservoir, which can also provide strong technical support to the exploration and development of oilfield.Since from 2013 in Xinglongtai Oil Production Plant, the sum of fracturing treatment wells is 100, the cumulative stimulation production has achieved 15 million tons, and the productivity per year has achieved 5 million tons. The advancement and improvement of fracturing technology, is playing an important role in the development of this oilfield, the reservoir which is low porosity and low permeability can be developed effectively. It can improve the overall lever of fracturing treatment in Xinglongtai Oil Production Plant, furthermore it has great meanings to increase the potential production of oilfield.
