牛圈湖油田属于典型的低产、低压、低渗油藏,经过多年的开采,单井产量不断下降,大部分井面临重复压裂增产的问题。为了进一步挖掘剩余油,提高单井产量,开展了新型暂堵剂的开发研究以及先导性试验,新型暂堵剂具有溶解性好、封堵作用强,现场试验结果表明,新型暂堵剂暂堵效果良好,增产效果明显。 Niujianhu Oilfield is a typical low-yielding, low-pressure, low-permeability reservoir. After years of production, single-well production has been declining, and most of the wells face the problem of repeated fracturing and stimulation. In order to further excavate remaining oil and improve single-well production, a new type of temporary plugging agent has been developed and pilot tested. The new type of temporary plugging agent has good solubility and strong plugging effect. The field test results show that the new temporary plugging plug temporarily blocks The effect is good, the effect of increasing yield is obvious.
