摘要
针对大庆火山岩储层破裂梯度变化大、微裂缝发育,造成压裂施工成功率低的实际情况,采用多裂缝解释模型描述了压裂液在火山岩储层中的压力降落特征,并定量给出了裂缝条数、裂缝体积数和滤失裂缝条数等描述裂缝的参数,这为完善压裂设计提供了依据。采用胶塞和粉砂工艺成功地进行了现场施工,通过ZS10井的应用说明,在火山岩储层使用多裂缝测试压裂解释技术和采用胶塞与粉砂工艺是可行的。
Aiming at the real situation of the breakdown gradient changing greatly, the micro-fractures growing, and the fracturing success ratio low for the volcanic reservoirs in Daqing oilfield, the multi-fracture interpretation model is used to characterize the pressure drop of the fracturing fluid in the volcanic reservoirs, and provide the fracture-describing parameters quantitatively, such as the quantity and the volume of fractures, and the quantity of filtration fractures etc., which offers the ground to improve the fracturing design. With the techniques of gelling and silt, the field fracturing operation is conducted successfully. By the application in Well ZS 10, it shows using the fracturing interpretation technology and the techniques of gelling and silt is feasible in the volcanic reservoirs.
