摘　　要：伊拉克米桑油田地质结构复杂,前期主要是采用直井的模式对复合盐下Mishrif储层进行开发,为实现少井高产和快速上产的要求,从工程地质特点、水平井的剖面和井身结构设计、实际作业情况以及工程技术措施等方面对Mishrif储层的水平井进行了详细分析。结果表明:Mishrif储层水平井的成功实施实现了直井到水平井的突破及普及。水平井的单井产量为直井的2~3倍。目前Mishrif储层已经全部采用水平井开发,为少井高产创造了条件。The geological structure of the Missan Oilfield in Iraq is complex,and the pre-operation wells mainly use the vertical well mode to develop the Mishrif reservoir under the anhydrite salt,and in order to achieve the requirements of“few wells and high production”and rapid production,the horizontal well is proposed to develop the Mishrif reservoir.The horizontal wells of Mishrif reservoir are analyzed in detail from the aspects of engineering geological characteristics,horizontal well profile and well casing structure design,actual operation and engineering and technical measures.The successful implementation of horizontal wells in the Mishrif reservoir has achieved a breakthrough and popularization from vertical wells to horizontal wells.The production of a single well in a horizontal well is 2~3 times that of a vertical well,and the development of horizontal wells has been realized in the Mishrif reservoir,which has created conditions for“less wells and higher production”.
