塔河油田为碳酸盐岩超深、超稠油油藏,应用掺稀降黏工艺开发,机械举升方式主要以液压反馈式抽稠泵和稠油电泵为主。随着稠油开发进入中高含水期,常规举升工艺配合掺稀降黏开采技术面临着含水乳化、腐蚀结垢、异常率高、经济效益差等难题,急需寻求更加高效的开采工艺。针对含水稠油井举升的特点,从工艺优选和技术替代的思路出发寻找解决办法,优选螺杆泵替代抽稠泵和电泵,应用水溶性降黏剂替代掺稀油,形成地面驱动螺杆泵配合水溶性降黏剂稠油开采技术。通过现场6口井的应用,平均稀稠比下降0.3,平均单井日节约稀油4.9 t,单井日增油3.8 t。现场应用的成功,证明了该技术对含水稠油井具有适应性强、应用效果好、经济效益突出的优势,进一步拓宽和完善了稠油高效开发的技术体系。

Tahe Oilfield is an ultra-deep and ultra-heavy carbonate oil reservoir, which needs to mix with dilute oil to decreasing viscosity The mechanical lifting method is mainly hydraulic feedback heavy-oil pump and heavy oil electric pump. As the development of heavy oil enters the middle-high water cut period, the existing processes are facing the problems of water-cut emulsification, corrosion and scaling, high abnormal rate and poor economic benefit. It is urgent to seek more efficient and economical recovery technology. According to the lifting characteristics of heavy oil wells with water cut, the solution is found from the thought of process optimization and technology substitution. The screw pump is optimized to replace the old pumps, and the water-soluble viscosity reducer is used to replace the dilute oil. Therefore the heavy oil recovery technology by the combination of ground driven by screw pump and water soluble viscosity reducer is formed. Through the application of 6 wells, the average lean ratio decreased by 0.3, for single well per day in average, 4.9 tons of dilute oil are saved, and 3.8 tons of oil are increased. The success of the field application proves that this technology has the advantages of strong adaptability, good application effect and outstanding economic benefit for water-bearing heavy oil wells, and further widen and improve the technical system of high efficiency development of heavy oil.
