摘要:
渤海油田稠油测试作业期间，稠油及天然气计量误差大，气量小时无法计量。运用保温管、地面蒸汽加热同心管，从井下到计量罐全流程加热保温，降低原油黏度；对分离器内部进行改造，采用差压式液位变送器、聚结式过滤器、精密气体计量管汇等技术，实现对稠油和天然气产量的精准计量。案例C井原油比重09884（20℃）、黏度268045 mPa〖DK〗·s（50℃），采用稠油精准测试技术，消除了稠油中的泡沫，使油气分离更彻底，取得了准确的油气产量数据。该技术可获取油田后续开发需要的常规气样和分离器配样等，为开发方案编制提供可靠依据。
Abstract:
During heavy oil testing operation in Bohai Oilfield, the measurement errors of heavy oil and natural gas were large and it cannot be measured when the gas volume is small. In order to solve these problems, thermal insulation pipes and concentric pipes heated by surface steam were used to heat and insulate during the whole process from downhole to metering tank to reduce the viscosity of heavy oil. In addition, the inside of the separator was reformed, and the precise metering of output of heavy oil and natural gas was realized by using some technologies such as differential pressure liquid level transmitter, coalescent filter and precise gas metering pipe. In the example of well C, the specific gravity of crude oil was 09884 (20 ℃) and viscosity was 268045 mPa〖DK〗·s (50 ℃). The precision test technology of heavy oil was used to eliminate foam in heavy oil and make the separation of oil and gas more thorough, so as to obtain the accurate oil and gas production data. The parameters of conventional gas samples and separator samples can be acquired for subsequent development of oilfield using this technology, which can provide reliable basis for development planning.
