  • Simultaneous hydraulic fracturing of ultra-low permeability sandstone reservoirs in China: Mechanism and its field test
    Journal of Central South University, 2015
    Co-Authors: Jinzhou Zhao, Ke-wen Yang, Yongquan Hu, Xiu-juan Wang
    Abstract:

    Based on the impact of the stress perturbation effect created by simultaneous propagation of multiple fractures in the process of simultaneous hydraulic fracturing, a thorough research on the mechanism and adaptation of simultaneous fracturing of double horizontal wells in ultra-low permeability sandstone reservoirs was conducted by taking two adjacent horizontal wells (well Yangping-1 and well Yangping-2 located in Longdong area of China Changqing Oilfield) as field test wells. And simultaneous fracturing optimal design of two adjacent horizontal wells was finished and employed in field test. Micro-seismic monitoring analysis of fracture propagation during the stimulation treatment shows that hydraulic fractures present a pattern of complicated network expansion, and the well test data after fracturing show that the daily production of well Yangping-1 and well Yangping-2 reach 105.8 t/d and 87.6 t/d, which are approximately 9.4 times and 7.8 times the daily production of a fractured vertical well in the same area, respectively. Field test reflects that simultaneous hydraulic fracturing of two adjacent horizontal wells can enlarge the expansion area of hydraulic fractures to obtain a lager drainage area and realize the full stimulation of ultra-low permeability sandstone reservoirs in China Changqing Oilfield. Therefore, simultaneous fracturing of two adjacent horizontal wells provides a good opportunity in stimulation techniques for the efficient development of ultra-low permeability reservoirs in China Changqing Oilfield, and it has great popularization value and can provide a new avenue for the application of stimulation techniques in ultra-low permeability reservoirs in China.

  • simultaneous hydraulic fracturing field tests in ultra low permeability sandstone reservoirs of Changqing Oilfield
    Chinese journal of rock mechanics and engineering, 2015
    Co-Authors: Ren La
    Abstract:

    The adaptability and the effect of simultaneous hydraulic fracturing in sandstone reservoirs of ultra-low permeability was investigated in the field tests in two adjacent horizontal wells, Yangping-1 and Yangping-2,located in Longdong area,Changqing Oilfield,China. The simultaneous fracturing treatment was performed in the two testing wells. Micro-seismic monitoring analysis of fracture propagation during the stimulation treatment indicates that hydraulic fractures present a pattern of complicated network expansion. The test data after fracturing show that the daily production of the well Yangping-1 and the well Yangping-2 reaches 132.3 and 109.5 m3/d respectively,which are approximately 9.4 times and 7.8 times the daily production of a fractured vertical well in the same area. It is also shown that the simultaneous hydraulic fracturing of two adjacent horizontal wells enlarge the expansion area of hydraulic fractures to obtain a larger drainage area and to realize the full stimulation of ultra-low permeability sandstone reservoirs in Changqing Oilfield.

  • Simple Analysis of Low Permeability Sandstone Reservoir Stable Production Countermeasures - Taking Jiyuan Oilfield Yuan 214 Chang 4-5 Reservoir as an Example
    Applied Mechanics and Materials, 2014
    Co-Authors: Meng Wang, Rui Hu, Tian Dan Shen, Ming Xu Lu
    Abstract:

    The efficient development of low permeability reservoir exploration and development at home and abroad has been a difficult and hot issues. Changqing Oilfield is the permeability, low pressure, low abundance of the "three low" oil and gas fields, is the world famous low permeability. In recent years, with the low permeability of Changqing Oilfield fast on the scale of production, development and gradually increase the difficulty, well production decreased year by year, oil layers, layer contradictions become increasingly prominent. Changqing Oilfield how old stable production, it will be a challenging task. In this paper, Changqing Oilfield per 214 Jiyuan Chang 4 +5 reservoir, for example, focuses on the reservoir of the reservoir by strengthening fine management and implement water policies, improve water technical control, good water injection, inject enough water, improve the capacity of the reservoir stable production, improve development effectiveness.

  • Geological Characteristics and Implementation Results under Tight Layer's Mixed Water Fracturing in Ordos Basin
    Applied Mechanics and Materials, 2014
    Co-Authors: Meng Wang, Rui Hu, Tian Dan Shen, Ming Xu Lu
    Abstract:

    The efficient development of tight oil exploration and development domestic and foreign has been a difficult, hot issues, using conventional reservoir reconstruction process, the yield increase is limited. Ordos Basin in the Chang 7 layers of tight oil reserves on behalf of a large scale, widely distributed, in order to reinforce to achieve fifty million tons of Changqing Oilfield stable long-term strategic objectives of the resource base and improve the tight oil well production, faced with enormous challenges. For Changqing Oilfield tight reservoir geological features, learn from foreign experience in tight oil development success, positive change in Changqing Oilfield reservoir reconstruction,approach to volume fracturing as a concept, greatly contributed to the Chang 7 represented tight reservoir of cost effective development, the effect is significant, strategic breakthrough.

    Petroleum Engineering Construction, 2010
    Co-Authors: Feng Y, Zhang Jianxiao
    Abstract:

    The well site standardized design in Changqing Oilfield is promoted based on digital management thought and raises the optimal efficiency of manpower resource and the management efficiency of production and operation.Furthermore,the standardized design optimizes and simplifies the well site plan layout and equipment so as to reduce construction cost.The features of well site design,applied process techniques and the implementation benefit of the well site standardized design are discussed in this paper.It is pointed out that the construction cost of a standardized well site for ten-well mode reduces by 51%.
