摘要/Abstract

摘要： 针对南海西部油田水平井开发后期高含水问题，提出调流控水筛管与轻质颗粒充填配合的精细控水技术。首次采用渗流理论分析与物模实验相结合，论证了筛管充填轻质颗粒后的轴向渗流阻力远大于径向渗流阻力，结合调流控水筛管能够实现水平井流动剖面均衡开采的功能，可实现水平井充填防砂的同时，实现全井段精细控水，较于传统控堵水工艺，其具有无需找水、储层保护风险低等优点。该技术在南海西部油田进行了先导试验，实现了由于出砂和高含水导致关停的涠洲11-4油田A22井成功复产，且措施后含水率下降20％、日增油 90 m³，为海上油田水平井控水技术发展提供了一条新思路。

Abstract:

Aiming at the problems of high water cut in the late stage of horizontal well development in Western South China Sea oilfield, Put forward water control technology of water control sieve tube with light granule filling. For the first time, combination of seepage theory analysis and physical model experiment, used to demonstrate that the axial seepage resistance after filling light particles with sieve tube is much greater than the radial seepage resistance. Combined with the flow control sieve tube, the flow profile of horizontal well can be equally exploited, the sand control of horizontal well can be realized, and the fine water control of the whole well section can be realized at the same time. Compared with the traditional water shutoff technology, it has the advantages of no need to find water and low risk of storage and protection. The pilot test of this technology has been carried out in the western South China Sea oilfield, and the successful resumption of well A22 in WZ 11-4 oilfield shut down due to sand production and high water cut has been realized. The water cut has been reduced by 20% and the oil production has been increased by 90 cubic meters per day after the measures, which provides a new idea for the development of water control technology in horizontal wells of offshore oilfields.
