摘要:
 东海油田西湖某高产高含蜡油气井测试作业期间，地面流程结蜡，井内返出碎屑堵塞油咀管汇、原油燃烧不充分。从固控、加热保温及原油燃烧工艺等方面细化研究，采用空心电加热杆、高强气凝胶隔热管和地面蒸汽加热同心管，实现井下到计量罐全流程加热保温，确保原油温度始终保持在析蜡点以上，提高含蜡原油流动性；采用井下割缝管和井口捕屑器组合工艺，预防井内返出碎屑堵塞流程；优选原油燃烧器及优化燃烧配气参数，为高产原油燃烧提供保障。现场实践证明，该技术解决了高产高含蜡油气井测试难题，为东海西湖某区块的后期评价积累了配套技术。
Abstract:
 During the test operation of a high yield and high wax content oil and gas well in Xihu, Donghai Oilfield, wax easily deposits on the surface flow, oil nozzle manifold is easily blocked by debris returned from the well and crude oil insufficiently combusts. In this paper, solid control, heating and insulation, and crude oil combustion technology are studied. The hollow electric heating rods, highstrength aerogel insulation pipes and surface steam heating concentric pipes are used to realize the heating and heat preservation in the whole process from downhole to the metering tank, to ensure that the crude oil temperature is always maintained above the wax precipitation point, and to improve the fluidity of waxy crude oil; in addition, the combined technology of downhole slotting pipe and wellhead chip collector is adopted. The optimized crude oil burner and combustion gas distribution parameters provide guarantee for highyield crude oil combustion. The field practice shows that this technology solves the testing problem of high yield and high wax content oil and gas wells, and accumulates supporting technology for the later evaluation of a block in Xihu, East China Sea.
