【摘要】：抽油泵的合理沉沒壓力是確定抽油機(jī)井管理的核心因素,是保證抽油機(jī)在穩(wěn)定高效下運(yùn)行的關(guān)鍵因素,也是延長油井免修期并且最終達(dá)到最佳經(jīng)濟(jì)效益的基礎(chǔ)。本文在充分調(diào)研國內(nèi)外大量相關(guān)文獻(xiàn)的基礎(chǔ)上,全面分析氣體、粘度、含水率、泵徑、產(chǎn)液量等多種因素對抽油泵合理沉沒壓力的影響,詳細(xì)敘述了抽油泵的工作原理及系統(tǒng)效率、泵效的計算方法,并制定了抽油泵合理沉沒壓力的設(shè)計思路和確定方法。根據(jù)不同油井的生產(chǎn)資料情況,確定油井產(chǎn)能預(yù)測是油井生產(chǎn)系統(tǒng)優(yōu)化的基礎(chǔ)。采用權(quán)重分配法,分別選擇產(chǎn)量、泵效、經(jīng)濟(jì)效益、系統(tǒng)效率、設(shè)備利用率五個目標(biāo)函數(shù)對抽油桿柱組合進(jìn)行優(yōu)選。同時針對不同油藏的特點(diǎn),并利用現(xiàn)場數(shù)據(jù)資料,確定以產(chǎn)量最高為優(yōu)選目標(biāo)對抽油泵合理沉沒壓力的確定方法。最后篩選了杏北開發(fā)區(qū)1個區(qū)塊進(jìn)行優(yōu)化設(shè)計,得出了合理沉沒壓力和下泵深度的合理范圍值,并且利用java軟件編制了針對該區(qū)塊抽油泵合理沉沒壓力的優(yōu)化設(shè)計軟件,該軟件能夠滿足油田現(xiàn)場生產(chǎn)的需要,油井的生產(chǎn)條件得到改善,使用效果良好。
[Abstract]:The reasonable sinking pressure of the pumping pump is the core factor to determine the well management of the pumping unit, the key factor to ensure the pumping unit to run under the stable and high efficiency, and the basis for prolonging the period of the oil well from repairing and finally achieving the best economic benefit. On the basis of investigating a large number of related documents at home and abroad, this paper comprehensively analyzes the influence of many factors, such as gas, viscosity, moisture content, pump diameter, liquid production and so on, on the reasonable sinking pressure of the submersible pump. The working principle, system efficiency and calculation method of pump efficiency are described in detail, and the design idea and determination method of reasonable sinking pressure of subsurface pump are worked out. According to the production data of different wells, it is the basis of optimizing the production system to determine the prediction of oil well productivity. Five objective functions of output, pump efficiency, economic benefit, system efficiency and equipment utilization ratio were selected to optimize the sucker rod string combination by weight distribution method. At the same time, according to the characteristics of different reservoirs and using the field data, the method of determining the reasonable sinking pressure of the submersible pump with the highest output as the optimum selection target is determined. At last, a block of Xingbei Development Zone is selected for optimum design, and the reasonable range of sinking pressure and depth of pump is obtained, and the optimum design software for reasonable sinking pressure of submersible pump in this block is compiled by using java software. The software can meet the needs of oil field production, the production conditions of oil wells are improved, and the application effect is good.
