一种水平井精准着陆的地质导向技术方法
摘要
Abstract
In order to effectively solve the difficulties of geological guidance of horizontal wells in complex structural areas,and improve the precision of target prediction and box drilling rate.Based on 3D seismic data,the apparent dip angle of each stratum and azimuth is accurately extracted by combining well and seismic velocity model,and the prediction of target depth is constantly corrected and refined while drilling through multi-element thickness modeling in real drilling.optimize the three-dimensional trajectory while drilling.After entering the box,the geophysical response characteristics are strengthened,the curves while drilling are extracted and inversed,and the imaging characteristics of the box are described by multielement spectrum and imaging technique.It has achieved good results in the drilling practice of shale gas horizontal wells of Wufeng-Longmaxi formation in northern Guizhou,which is high,steep and narrow,and has the potential to be popularized.The key technologies of MWD curve extraction,MWD curve inversion and characteristic element imaging provide effective support for horizontal well target prediction and guiding horizontal well to travel through the box,which can effectively ensure the accurate landing of horizontal well and promote the horizontal well box drilling rate and production.关键词
