摘　　要：塔里木盆地地下地质条件复杂,油气藏类型丰富多样,且埋藏超深,97%以上储量分布在埋藏超过3000m的油气藏中,构造描述的精度难以达到水平井设计的要求。近年来,随着勘探开发的深入,塔里木油田水平井的应用越来越广泛,精度要求越来越高,在厚度小于0.6m的超薄油层中成功完钻了一批水平井,还有在山前复杂地层、潜山型油藏、小型断块油藏、剩余油较分散老油田中完钻了一批水平井,通过摸索和实践形成了一套实用的水平井设计和跟踪方法,水平井的油层钻遇率达到80%以上,成功率超过90%,水平井配套技术日趋进步和完善。The underground geological condition of Tarim basin is so complex that there are so many types of reservoirs which are buried more than 3000m in depth and about 97 percent reserves is in it.Recently,because of expanding development,many horizontal wells were drilled in Tarim,at the same time the drilling technology is becoming more precisely.Besides drilling in mountain-front complex stratigraphic reservoir,buried hill reservoir,fault-screened reservoir and the reservoir with disperse remaining oil,horizontal wells also can be drilled in layer less than 0.6m.Through practice,this paper summarized a applied drilling design and tracking method of horizontal well,which has given the effective probability of penetration above 80 percent and success rate above 90 percent,so the coordinated technology become more improved and perfectly.
