【摘要】：随着大庆油田老区块开发的不断深入,剩余未动用储量绝大部分是有效厚度较小、储量丰度较低的难采储量,开采难度将越来越大。大部分油田虽然对采油设备采取了多种技术措施,但机械采油设备仍占据主导地位。但是机采方式繁多,械采油设备常常因为工作方式选或相应泵型的选择不当,使得其设计使用寿命或生产能力大打折扣,严重影响油田产量。但改变现有采油装置代价很大,除了必要的资金和物资,还要花费大量的人力。因此,在某种机械采油方式安装建设之前,做好机采举升方式的技术和经济评价工作,对充分发挥油井产能、提高采收率、最大限度的降低油田的投资和提高油田经济效益都起着重要作用。本文运用己有的技术进行了深入研究。依照对抽油机、螺杆泵、电泵的投资构成和成本构成的分析,界定了这三种举升工艺技术的投资和成本的构成,并从投入产出角度,建立了举升工艺技术的技术经济评价模型;根据盈亏平衡原理,建立了抽油机、螺杆泵、电泵三种举升工艺技术的经济极限产油量模型、经济极限成本模型和经济极限投资模型;通过利用单项指标评价模型和多项指标评价模型,对不同排量情况下的抽油机、电泵和螺旋泵在产量相同和产量不同时的应用进行了经济性优选;参照少而精原则、全面性的原则、科学性等原则,构建了举升工艺技术综合评价指标体系,该指标体系主要包括了经济性、技术方面和社会效果3个主指标,并在不同举升工艺技术综合评价中运用了理想解排序法。对不同举升工艺技术进行优选及经济评价,可为大庆油田在选择举升工艺技术时提供借鉴。
[Abstract]:With the deepening development of the old block of Daqing Oilfield, the remaining unproduced reserves are mostly refractory reserves with small effective thickness and low reserves abundance. It will be more and more difficult to exploit. Although most oilfields have adopted various technical measures for oil production equipment, mechanical production equipment still dominates. But there are many ways of producing oil by machine. The design life or production capacity of mechanical oil recovery equipment is often greatly reduced because of improper selection of working mode or pump type, which seriously affects oil field production. However, it is very costly to change existing oil recovery equipment. In addition to the necessary funds and materials, a large amount of manpower will be spent. Therefore, before the installation and construction of a certain mechanical oil recovery mode, the technical and economic evaluation of the mechanical oil recovery lifting mode will be done to give full play to the production capacity of the oil well and increase the oil recovery. It is very important to reduce the investment of oil field to the maximum extent and to improve the economic benefit of oil field. In this paper, we use the existing technology to carry on the deep research. According to the analysis of the structure of investment and cost of pumping unit, screw pump and electric pump, The investment and cost components of the three lifting technologies are defined, and the technical and economic evaluation model of lifting process technology is established from the angle of input and output, and the pumping unit and screw pump are established according to the break-even principle. The economic limit oil production model, the economic limit cost model and the economic limit investment model of the three lifting technology of electric pump, the pumping unit under the different displacement condition by using the single index evaluation model and the multiple index evaluation model, The application of electric pump and screw pump in the same output and different output is selected economically, and the comprehensive evaluation index system of lifting technology is constructed by referring to the principle of small but fine, comprehensive and scientific, etc. The index system mainly includes three main indexes of economy, technology and social effect, and the ideal solution ranking method is used in the comprehensive evaluation of different lifting technology, and the optimal selection and economic evaluation of different lifting technology are carried out. It can be used for reference when selecting lifting technology in Daqing Oilfield.
