摘要:
為考察稠油油田空氣輔助蒸汽驅的開采效果,開展了稠油油田空氣輔助蒸汽驅現場試驗研究工作。在齊40 塊蒸汽驅試驗區選擇原油瀕臨枯竭的、油藏已經發生嚴重蒸汽竄流和超覆的、亟待改變開發方式的5 個井組進行現場試驗,結果表明: 5 個試驗井組平均單井組日產油由14.8 t/d 升至16.1 t/d,油汽比由0.14 升至0.17;油層縱向動用程度明顯提高,分析認為是注入的空氣在縱向和平面上首先向蒸汽驅優勢方向波及,與殘余原油發生低溫氧化反應使孔隙中瀝青質沉積增加,降低油層滲透率,迫使蒸汽轉向,擴大蒸汽波及范圍。研究認為:空氣輔助蒸汽驅宜采用連續式空氣/ 蒸汽注入方式;汽氣比接近1∶40 可取得較高采收率;70 m 井距注入的空氣與地下原油發生低溫氧化反應,油藏溫度有所提高,產出氧氣含量可降到安全范圍內。現場試驗取得成功,利用空氣輔助蒸汽驅改善稠油油田蒸汽驅開發效果具有可行性。所選試驗井組存在的問題在普通稠油蒸汽驅井組生產后期具有普遍性,因此本文試驗方法和相關技術參數可為類似井組開展空氣輔助蒸汽驅試驗提供參考。
Abstract:
Field test and research was carried out on air-assisted steam flooding of heavy oil field to investigate its production effects. Five well groups whose development mode was in urgent need to be transformed due to the depleting crude oil and the serious steam channeling and overlapping in oil reservoirs were selected from the steam flooding test area of Qi 40 Block. And then field test was carried out on these five well groups. It is shown that the average daily oil production per well group of 5 test well groups is increased from 14.8 t/d to 16.1 t/d and the oil/steam ratio is increased from 0.14 to 0.17. The vertical producing degree of oil layers is increased significantly. It is indicated from the analysis that the injected air firstly sweeps in the predominant direction of steam flooding vertically and areally and low-temperature oxidation reaction happens between the injected air and the residual crude oil, increasing the bituminous sediments in pores. And consequently, the permeability of oil layers is decreased to force the steam to divert, so that the sweeping area of steam is enlarged. It is revealed that continuous air/steam injection is the suitable mode for air-assisted steam flooding; the recovery factor is higher when the steam/air ratio is close to 1:40; and if the well spacing is 70 m, the reservoir temperature will rise slightly and the content of produced oxygen can drop to the safety range after low-temperature oxidation reaction happens between the underground crude oil and the injected air. The success of field test demonstrates the feasibility of air-assisted steam flooding to improve the production of heavy oil fields. The problems of the selected test well groups are common in the late production stage of well groups in ordinary heavy oil reservoirs developed by steam flooding, so the test method and the related technical parameters in this paper can be used as the reference for the air-assisted steam flooding of similar well groups.
