摘要
为了改造近井地带和有效释放草104区块油井产能,针对草104区块油井出砂严重,常规防砂只会造成油井防不住出砂或完全防死导致油井不供液的问题,研发了纤维复合体的配方。通过实验确定出防砂纤维的浓度为1%~2%,纤维长度为10 mm,纤维的直径为15μm。纤维复合体的配方为偶联剂、增强剂、改性剂、增韧剂、ER树脂粉末、常温树脂、高温树脂、石英砂之间的质量比为0.05∶0.5∶0.5∶1∶3∶6∶4∶100。当温度达到350℃时,纤维复合体的抗压强度高于高温树脂涂覆砂,具有更好的耐温性能。该技术在草104区块的应用取得了突破,相比常规机械防砂,周期增油5051.1 t,平均含水降低2.3%,平均油气比提高0.38,产出投入比达到4.6,取得非常好的经济效益,在类似稠油区块具有很高的推广价值。
In order to renovate the near-well zone and effectively release the productivity of the oil well in block 104, aiming at the problem of sand production in the oil well of block 104 is serious and the conventional sand control will only cause the oil well to prevent sand or completely prevent the oil from being supplied, the formulation of the fiber composite was thus developed. It was determined by experiments that the concentration of the sand control fiber was 1%~2%, the fiber length was 10 mm, and the diameter of the fiber was 15 μm. The fiber composite is formulated to have a mass ratio of coupling agent, reinforcing agent, modifier, toughening agent, ER resin powder, room temperature resin, high temperature resin, quartz sand of 0.05∶0.5∶0.5∶1 ∶3 ∶6 ∶4 ∶100. When the temperature reaches 350 °C, the compressive strength of the fiber composite is higher than that of the high temperature resin coated sand, and it has better temperature resistance. The technology has achieved breakthrough in the application of C104 block. Compared with conventional mechanical sand control, the cycle oil increase is 5 051.1 tons, the average water content is reduced by 2.3%, the average oil-gas ratio is increased by 0.38, and the output-to-input ratio is 4.6, which has achieved very good economic benefits. It has a high promotion value in similar heavy oil blocks.
