摘要: 齐齐哈尔富拉尔基油田拥有丰富的浅层稠油资源,油藏埋深浅,油层薄,由于地面条件限制不能采用直井开发,长城钻探工程有限公司钻井三公司在该区块施工了7 口浅层水平井. 浅层水平井钻井因地面与目的层距离短,钻井完井过程中面临一些特定的技术难题. 针对施工难点进行分析,从钻具组合设计、地质导向技术和钻井液优化设计三方面出发,实现安全优质高效钻井.Abstract: Fularchi oilfield in Qiqihar is rich in heavy oil resources with shallow and thin reservoir.Because of the restric-tion of surface conditions, vertical wells can not be applied in the development.7 shallow horizontal wells were constructed in this block by 3rd drilling branch of Great Wall drilling company.Due to the short distance from the ground to the target layer in shallow horizontal drilling, some specific technical problems will be showed up during the process of drilling and completion.The difficulties during the construction are analyzed; safe, high quality and efficient drilling are achieved by the design of BHA, geology steering technology and optimized design of drilling fluid.
