高压水射流解堵技术的研究及应用

近几年发展起来的高压水射流解堵是用于高含水期油田和低渗透油田增产增注的新技术，该工艺不但具有施工简单、能量集中和处理深度大等特点，而且可根据地层堵塞程度选择射流压力、旋转速度、处理时间和层位。从动力学角度对高压水射流解堵的基本原理、工艺技术及有关的计算方法加以论述，并运用实际并例证明了该技术解堵增产效果显著。

A Study of Plug Removing Technique with High Pressure Water Efflux and its Application

Plug removal with high pressure water efflux is a new technique developed these years to be used for increment of production and injection in high water cut stage oilfields and low permeability oilfields. The application of the technology in the area around wellbore is not only featured with simple operation,power concentration and deep treatment, but jet pressure, rotatlyn velocity, treatment time and formation to be treated may be selected according to degree of formation damage. At the angle of dynamics, this paper discusses basic principle,technology and pertinent calculation method of plug removing technique with high pressure water efflux, and actual well examples prove that application of the technique may obtain an obvious effect of removing plug and increasing production.
