地面测斜仪在煤层气井组压裂裂缝监测中的应用
|
摘要
针对山西宁武区块煤层压裂施工中加砂困难,对裂缝扩展情况认识不足等难题,为了更好地认识煤层气井压裂裂缝的形态和扩展规律,指导该区块其他井组合理部署井网,优化压裂设计,采用地面测斜仪压裂裂缝监测技术,对宁武区块M15井组5口井压裂裂缝进行了监测,获得了该井组压裂裂缝的几何形态、方位、倾角等参数,进一步认识了该区块煤层气井压裂裂缝的复杂性,为部署井网和优化压裂设计提供了科学依据。
Fracturing operation in the coal seam of Ningwu block in Shanxi province had problems of proppant input difficulty and inadequate understanding of fracture propagation.In order to have a better understanding of the shape and propagation of fracturing fractures,to guide wells placement in the block and to optimize fracturing design,surface tiltmeter was used to detect fracturing fractures in 5 wells of the M15 well group in Ningwu block,thus obtained fracturing parameters such as geometry,azimuth and dip.The result enables us to have a deep understanding of the complexity of fracturing fractures in coalbed methane(CBM) wells,and provides scientific reference for arranging well pattern and optimizing fracturing design.
