摘　　要：水平井以最佳的井斜角和入层深度着陆中完是实现目标产能的关键和基础保障,但由于河流相油田储集层具有横向变化大、油水关系复杂、油藏类型多样等特点,储集层特征难以准确刻画和精准预测,给水平井着陆带来了较大的难度和挑战。在对渤海Q油田已钻井储集层特征认识的基础上,通过研究形成了储集层模型分类及着陆原则、基于优选邻井的储集层精细预判方法、储集层内夹层随钻识别技术等指导水平井着陆的技术方法,实现了水平井着陆位置储集层特征的精准预判和随钻快速识别。在Q油田16口水平井作业应用验证中取得了较好的效果,有效提高了水平井着陆成功率和质量,在同类型油田中具有借鉴意义和推广价值。Horizontal well landing halfway through well completion with optimum deviation angle and entry depth is the key and basic guarantee to achieve the target productivity.However,the reservoirs in fluvial facies oilfield has the characteristics of large lateral variation,complex oil-water relationship and diverse reservoir types,reservoir characteristics are difficult to accurately depict and predict,which brings great difficulty and challenge to horizontal well landing.On the basis of studying the characteristics of the drilled reservoirs in Bohai Q oilfield,the techniques of guiding horizontal well landingwere formed,that is,reservoir model division and corresponding landing principle,reservoir fine prediction based on the optimized offset wells and identification of interlayer in reservoir with drilling,which realizes the accurate prediction of the reservoir characteristics of landing position of horizontal well and rapid identification while drilling.Good results have been obtained in the application and test of 16 horizontal wells in Q oilfield.It effectively improves the success rate and quality of horizontal well landing,and has reference value and promotion value in the same type of oilfield.
