【摘要】：近年来,吉林油田开发不断深化,老井重复压裂频次不断增加,地层压力也不断降低,近井地带也越来越疏松,压后地层出砂也越来越严重,需要对原有的防砂压裂体系进一步优化和细化,来进一步延长油井免修期以及满足二、三次采油低闭合压力油层生产需要。目前吉林油田主要应用核桃壳、树脂砂和纤维进行防砂压裂,对于闭合压力较低的地层采用核桃壳防砂,主要应用于吉林油田扶余、新木采油厂、大老爷府油田和长春岭油田,取得较好的防砂和增产效果;对于中高闭合压力储层主要采用树脂砂防砂压裂技术,主要应用于深层气井,也取得了较好的防砂效果。本问在原有防砂压裂基础上进一步优化防砂参数,借助室内试验评价已有防砂材料的技术性能指标,评价多种混合防砂材料的防砂性能指标,研究在同一层井应用两种或多种防砂材料进行防砂或者混合材料进行防砂,形成多层防砂屏障,从而进一步提高防砂效果和增产效益。
[Abstract]:In recent years, the development of Jilin oil field is deepening, the frequency of repeated fracturing in old wells is increasing, the formation pressure is also decreasing, the area near the well is becoming more and more loose, and the sand production of formation after pressure is becoming more and more serious. It is necessary to further optimize and refine the original sand control fracturing system to further prolong the period of oil well repair and to meet the production needs of the second and third oil recovery low closed pressure reservoirs. At present the walnut shell is mainly used in Jilin Oilfield. Resin sand and fiber for sand fracturing, for the formation with low closure pressure using walnut shell sand control, mainly used in Jilin oilfield Fuyu, Xinmu oil production plant, Da Laoyefu oil field and Changchun oilfield. The effect of sand control and production increase is better; For middle and high closed pressure reservoir, resin sand sand fracturing technology is mainly used, mainly used in deep gas wells, and good sand control effect has been achieved. The sand control parameters are further optimized on the basis of original sand control fracturing. With the help of laboratory tests, the technical performance indexes of existing sand control materials are evaluated, and the sand control performance indexes of many kinds of mixed sand control materials are evaluated. This paper studies the application of two or more kinds of sand control materials to sand control or mixed materials in the same well to form a multi-layer sand control barrier so as to further improve the effect of sand control and the benefit of increasing production.
