喇嘛甸油田大砂量压裂工艺技术研究

Research on the Fracturing Technology of Increasing the Amount of Sand in Lamadian Oilfield

大砂量压裂与常规压裂相比有效期平均延长,增油效果明显。全井最大加砂量可达45m3,单缝最大加砂量20m3,最大缝长比0.19。

In Daqing Lamdian oil field, according to the characteristics using the larger amount of propping agent and fracturing fluid, easily producing sand and damaging the formation in this fracturing technology, resin sand technique for sand control is studied. Through field application, it is indicated that under certain reservoir conditions, increasing the amount of sand is an effective means of improving the stimulation effects. Comparing a conventional fracturing with the amount of sand fracturing technology, the period of validity of producing oil is Ionger and the effect of increasing oil production is obvious. The largest amount of sand is 45 m^3 in stimulation well and 20 m^3 in single-slit. The largest ratio of fracture length to well space is 0. 19
