水平井找水技术现状与快速找水方法探讨

Present situation of water detection technology by horizontal wells and discussion on rapid water detection method

水平井已成为低渗透、超低渗透油藏最经济有效地开发方式,但生产过程中,水平井见水、水淹情况日益突出,见水水平井有效治理难度大。为此,对国内外油田水平井找水测试技术进行全面调研分析,对不同找水技术原理、特点、应用界限、仪器输送方式进行了综合评判,通过技术集成、融合创新,提出了水平井高效快速找水测试技术发展方向,设计了水平井高效快速找水测试技术方案。该测试技术方案能够适应不同液量井找水测试,为水平井高效快速找水测试研发提供了借鉴。

The development manner by horizontal wells is the most effective development method for low permeability and ultra-low permeability reservoirs.However,in the production process,the water breakthrough and water flooding of horizontal wells are increasingly prominent,and it is difficult to effectively control water breakthrough by horizontal wells.Therefore,this paper makes a comprehensive investigation and analysis on water detection and testing technology of horizontal wells at home and abroad.The principles,characteristics,application limits and instrument transportation modes of different water exploration technologies are comprehensively evaluated.Through technology integration and integration innovation,the development direction of efficient and rapid water detection and testing technology for horizontal wells is proposed.The technical scheme of efficient and rapid water detection and testing for horizontal wells is designed,which can adapt to the water detection and testing of wells with different fluid volumes,and provides the basis for the development of efficient and rapid water detection and testing for horizontal wells.
