摘要
模拟胜利油田坨 11南地层条件 ,研究了一种以黄原胶为主剂的新型驱油剂BP 1的性能。通过实验研究表明 ,它具有较好的增粘性能 ,能够耐较高的温度 (>6 0℃ ) ,具有良好的注入性和溶解性 (90min全部溶解 )。驱替实验表明它能够提高采收率 ,投入产出比为 1∶3.85 ,经济效益明显 ,是一种性能优良的驱油剂。
Under the condition of simulated formations of south Tuo-11 in Shengli oil field, the behaviors of new type oil displacement agent BP-1 whose main component is xanthan gum have been studied. The experiment shows that the agent has good viscosified action, higher temperature resistance(760℃) and good injection and solubility property(completely dissolved in 90 minutes). The displacement experiment presents that the agent can improve the recovery (input-output ratio reaches 1∶3.85) and bring us much benefit. So BP-1 is a good one.
