摘要
水平井开发设计中的一个重要问题就是如何确定水平井段的合理长度.水平井段的长度不仅影响水平井的单井产量、钻井成本和泄油面积,而且影响油田的钻井数目和开发投资.本文将水平井筒内的流体流动和油藏内的流体渗流作耦合考虑,从理论上推导出了水平井段合理长度的求解方程,提出了水平井段合理长度的确定方法,并用实例验证了该方法的合理性和可靠性.
How to determine the optimum length of lateral segment is one of the important issues in making the horizontal_well development plans, because the lateral segment length will have an impact both on the single?_well production, drainage area and drilling cost and on the whole?_field well numbers and development investment. By coupling fluid flow in lateral borehole and percolation in reservoir, an equation to calculate the optimum length of horizontal segment has been theoretically derived, forming a practical method to determine the optimum lateral length. Its reasonableness and reliability are confirmed by an application case.
