摘要:
稠油的開采方式主要是降低原油黏度,增加其流動性。由于原油的黏度對于溫度極其敏感,熱采開采方式備受關注。以渤海油田A 區的實驗井為例,介紹了射流泵井以多元熱流體為動力液在同心管井筒的傳熱特點,研究了熱流體在井筒各部分的傳熱過程,建立了綜合傳熱系數的計算方法以及井筒溫度場模型,根據相應的溫度場求解流程,編制軟件,并以實際射流泵生產井為例進行計算。實際測量結果與軟件計算結果存在8.87% 的誤差,可以為后續海上稠油油田射流泵井工況診斷和參數優化提供保障。
Abstract:
The exploitation mode of heavy oil is mainly to decrease the viscosity of crude oil and increase its fluidity. The viscosity of crude oil is extremely sensitive to temperature, so the thermal recovery modes are much concerned. In this paper, the experimental well in Block A of Bohai Oilfield was taken as an example. The characteristics of heat transfer in the concentric borehole of the well equipped with jet pump by taking the multi-component thermal fluid as the power fluid were introduced. Then, the heat transfer process of thermal fluid in each part of the borehole was investigated, and the method for calculating the combined heat transfer coefficient was developed. In addition, the borehole temperature field model was established, and the software was programmed according to the corresponding temperature field solution process. Finally, the calculation was carried out with one actual production well equipped with jet pump as the example. It is shown that the error between the actual measurement value and the calculation result is 8.87%. It is proved that the research results can provide the guarantee for the working condition diagnosis and parameter optimization of wells equipped with jet pump in offshore heavy oil fields.
