开发后期分层测压技术的试验与评价

Test and Evaluation of Zoning Pressure Detection at the Late Stage of Oilfield Development

针对河南油田高含水开发后期细分开采的需求,如何准确、及时、经济有效地录取到分层的压力,对指导开发方案的部署显得愈来愈重要。对近几年油田开展试验的油井及常关井分层测压技术、注水井分层测压技术、环空不停抽分层测压技术进行了应用评价,并提出了利用不同的分层测压技术进行多级找堵水与测压一体化、在线对封隔器验封等拓展技术应用的新思路。

According to the needs of layer subdivision at the late stage of waterflooding in Henan Oilfield,how to accurately and timely,economically and effectively obtain stratified pressure was getting more and more important to guide the deployment of oilfield development plan.The application of zoning pressure detection in the tested and conventional shut-in wells,water injection well,keep drawing in annulus was evaluated.It is proposed to use of pressure test technology for integration of multistage water plugging and pressure test and on-line testing of packer seal detection to put forward a new idea in the expand technology application,which provides a new idea for technical development.
