摘　　要：选取中东M油田Asmari和Mishrif灰岩储层高矿化度地层水为研究对象,通过水质分析和结垢趋势预测,考察了该油田高矿化度地层水结垢特性。通过室内防垢实验,开展了化学防垢剂优选和金属防垢器防垢效果评价,结果表明,将优选的硫酸钙防垢剂ZT-16与碳酸钙防垢剂ZT-00按照不同比例复配后形成的复合防垢剂HSI适合于M油田高矿化度地层水防垢,这种复合防垢剂与金属防垢器联合使用不仅可以取得良好的防垢效果,而且能够有效降低化学防垢剂用量,从而达到控制注入成本的目标。上述研究成果对高矿化度油田地层水结垢预测与防垢具有借鉴意义。With infill well technique widely used inoffshore oilfields, the anti-collision problem has become one of the main problems that seriously af-fect domestic wells drilling safety. The model was built based on the theory of elastic waves in spheri-cal spreading and absorption attenuation, and was used to analyze the well casing head vibration sig-nals of three risk wells adjacent to A16 well to be drilled in WZll-1N oilfield, and the relative inter- well distance between monitored drill bit and the adjacent wells was obtained. The result is almost the same with the COMPASS scanning in anti-col-lision risk segment. The prediction model can be used as a method to predict relative inter-well dis-tance with real-time and quick characteristics, and can provide a reference for fld anti-collision job.
