摘　　要：冀东油田马头营凸起馆陶组稠油油藏中浅层,构造幅度低,油层薄,原油黏度大。该区块所钻油井造斜点高、井斜大,常规试油工艺无法满足生产需求。对射孔、测井、排液、挤注灰四项工艺深入研究,形成了与之相适应的试油配套技术。陀螺定向射孔技术结合井深轨迹,选择合理射孔方位,有效避免沟通下部水层;爬行器电缆测井技术输送测井仪器达目的层段,完成测井采集作业;双空心抽油杆内循环电磁加热螺杆泵排液技术通过增温循环,解决高凝油流动难题;挤注灰封层工艺技术提高水泥塞顶替效率。唐XXX井根据实际井况,采取双空心抽油杆内循环电磁加热螺杆泵排液工艺,排液效果显著,获日均产油8.12 m;唐XX井采取挤注灰封层工艺,封层成功,提高了油气产能。该配套技术的应用为冀东油田相似油藏勘探开发提供了借鉴。The characteristics of the heavy oil reservoir in the middle and shallow formation of Guantao Formation in Matouying uplift of Jidong Oilfield are low structural amplitude,thin reservoir and high crude oil viscosity.The wells drilled in this block have high kick off point and large deviation,which makes it difficult for the conventional oil testing process to meet the production demand.In this paper,an oil testing matching technology is formed by analyzing the four technologies of perforation,logging,liquid drainage,and cement injection deeply.Combing the gyro directional perforation technology with well depth trajectory technology can select reasonable perforation orientation to effectively avoid connecting with the lower water layer.Then,the crawler cable logging technology transports logging tools to the target formation to complete the logging acquisition.The drainage technology of double hollow rod internal circulation electromagnetic-heating progressing cavity pump solves the problem of the flow of the high pour point oil by temperature increasing circulation.Cement plugging displacement efficiency can be improved by cement injection sealing technology.According to the actual well condition,Well Tang XXX adopts the drainage technology of double hollow rod internal circulation electromagnetic-heating progressing cavity pump,which improves liquid discharge effect remarkable and the average daily oil production reaches 8.12 m^(3).Besides,the cement injection sealing technology was also adopted in Well Tang XX successfully,which improved the oil and gas production capacity.The application of the matching technology provides a reference for the exploration and development of similar reservoirs as Jidong Oilfield.
