【摘要】：在油田的注水开发中,由于客观地质特征、储层特征,注水开发的难度越来越大,成本越来越高,影响了油气田的高效开发。低频脉冲波增产技术是一种新的提高采收率方法,通过向储层施加振动能量,利用振动波在地层的传播,使储层孔隙介质及流体性质产生各种物理化学变化,从而改善油层渗流条件,解除油层堵塞,疏通油流通道,提高水驱的波及效率,达到油井增油、水井增注的目的,并且试验显示出适当的低频脉冲波动可以改善水驱效果,降低残余油饱和度,提高水驱采收率。本文分析比较了井下和地面脉冲发生方式,重点研究了脉冲注水地面装置。同时完成了储气蓄能器型地面脉冲发生器和液压型地面脉冲发生器的初步设计,根据两种脉冲发生器的比较,认为液压型地面脉冲发生器较为适合地面脉冲注水。同时,应用脉冲波在注水管道中的传输模型,分析了影响脉冲传输的因素;应用脉冲在管道传输过程中脉冲的衰减规律,分析了影响脉冲衰减的因素;应用振动边界条件下的流体渗流模型,分析了影响脉冲注水效果的主要因素。所得到的认识与建议对脉冲注水地面装置的设计及实现具有参考价值。
[Abstract]:Due to the objective geological characteristics and reservoir characteristics, water injection development is becoming more and more difficult and the cost is higher and higher, which affects the efficient development of oil and gas fields. Low frequency pulse wave is a new method to increase oil recovery. By applying vibration energy to reservoir and utilizing vibration wave to propagate in formation, various physical and chemical changes of pore medium and fluid properties of reservoir are produced. In order to improve the seepage condition of reservoir, remove reservoir blockage, clear oil flow channel, improve the sweep efficiency of water flooding, achieve the purpose of oil well increasing and well increasing injection, and the experiment shows that proper low frequency pulse fluctuation can improve the water drive effect, Reducing residual oil saturation and increasing water flooding recovery. This paper analyzes and compares the underground and surface pulse generation methods, and focuses on the research of pulsed water injection surface equipment. At the same time, the preliminary design of ground pulse generator and hydraulic ground pulse generator for gas storage accumulator are completed. According to the comparison of the two kinds of pulse generators, it is considered that the hydraulic ground pulse generator is more suitable for surface pulse injection. At the same time, using the transmission model of pulse wave in water injection pipeline, the factors influencing pulse transmission are analyzed, and the attenuation law of pulse in pipeline transmission is applied to analyze the factors affecting pulse attenuation. The main factors affecting the effect of pulsed water injection are analyzed by using the fluid seepage model under the vibration boundary condition. The knowledge and suggestions obtained are valuable for the design and implementation of pulsed water injection ground equipment.
