塔里木盆地巴楚隆起区地表条件复杂、岩性横向变化大,历年地震资料品质较差.选择激发井深时,应考虑激发岩性、近地表、地震、地质等资料分析地震波的传播速度、传播路径、地震成像等条件对激发的影响进行井深设计.应充分考虑潜水面、虚反射界面、子波形态、低频带等因素对地震资料品质的影响;选择激发药量时,根据地震地质条件选择药量,合理控制岩体动能与传播速度的比率;选择扪井方式时,考虑扪井材料与井壁的耦合关系,选用模量较大、变形较小的封填材料以利于提高激发效果.
The surface conditions of Bachu uplift in Tarim Basin are complex, the lateral variation of lithology is large, and the quality of seismic data over the years is poor.When the depth of excitation is selected, the propagation velocity and propagation path of seismic wave should be analyzed considering the induced lithology, near surface, seismic and geological data, , Seismic imaging and other conditions to stimulate the well depth design should take full account of the diving surface, the virtual reflection interface, wave form, low frequency band and other factors on the seismic data quality; choice of excitation dose, the selection of drugs based on seismic geological conditions And control the ratio of kinetic energy and propagation velocity of rock mass rationally. When choosing the method of single-well mode, considering the coupling relationship between the mesoporosity well and the well wall, the sealing material with larger modulus and smaller deformation is selected to improve the excitation effect.
