摘要:
根据水电相似原理,设计直井压裂井网实验模拟模型,研究正对式和交错式排状井网条件下渗流场分布规律,及裂缝方位、裂缝穿透比和井网排距对渗流场分布的影响.研究表明,压力等势线以裂缝为轴呈椭圆分布,裂缝穿透比越大,等势线密度越大,压裂井附近渗流由径向流向线性流转变趋势就越大;相同注采压差情况下,排距越大,裂缝周围地层压力保持水平越低,流体渗流过程中压降损失越大;在相同生产条件及井距排距情况下,交错式排状井网开发过程地层压力保持水平优于正对式排状井网.
Abstract:
A water-electricity imitation experiment was made according to the water and electricity resembling principle. The potentiometric contour, the influence of fracture orientation and fracture penetration ratio on distribution were studied under the conditions of the five-spot, opposite and cross row vertical hydraulic well pattern. The experimental results show that the pressure equipotential line is distributed elliptically with rotating by taking the fracture as axis. With the increase of the fracture penetration ratio, the transforming tendency from radial flow to linear flow around the fracture becomes larger. With the same injection/production pressure difference, the pressure around the fracture becomes lower with the increase of line distance. Under the same production state and well distance, the maintenance of pressure in the cross row well pattern is greater than that in the opposite row well pattern.
