在斜井(水平井)井下压力测试时,极易造成测试卡断等事故.以13-238井为例,对斜井落物井况进行了分析,简述了打捞落井仪器施工设计及施工过程.成功的打捞技术为同类或水平井况实施打捞作业提供了借鉴经验.

分层注水是解决油田开发层间矛盾的主要措施之一,是一种先进的工艺,但受井深、低渗、高温高压等多种因素影响,分注合格率较低.本文主要介绍影响分层注水工艺的原因及基本对策,具有良好的指导作用.

As the deepening of oilfield development, deviated wells are increasingly used. Beam pump diagnostic technique for such well is developed in accordance with problems such as severe wear between pumping rod and tubing and between tubing and casing, rod thread-off, pump damage, low pump efficiency, and short pump inspection period. The application of this technique can aware the operating status of deep well timely, diagnose the wear of rod at different depth, and optimize rod string. This technique can improve pump efficiency, extend pump inspection period, and solve problems of deviated well production and management.

针对文东油田气举采油井深度较大、高温高压、高气油比等特点,开发了三参数同步测试工艺及分析技术.该技术的应用丰富了测试资料内容,解决了困扰试井工作者多年的深度、压力、温度测试不同步的问题,满足了气举井资料录取的需要.

针对综合测试诊断仪资料分析单一,不利于有杆泵诊断测试资料的管理扣综合运用的现状,开发了有杆泵诊断分析软件.该软件较好地满足了油田开发过程中对监测信息的需求,具有较强的实用性和推广价值.

针对目前测试堵头在使用过程中存在的弊端,研制了多功能测试堵头.该堵头结构简单、方便实用、安全可靠,有效解决了钢丝的防腐问题,杜绝了测试"冒顶"事故的发生,经现场多次试验及应用,效果明显.

A three parameter synchronous test process is implemented by surface intelligent depth meter and a high precision storage electronic pressure meter, for which working principles are given. Field application effect is analyzed, the working status of gas lift valve and tube leaking positions could be accurately judged by using the technique so as to provide basis for analyzing the working conditions of gas lift wells. Pressure and temperature are used for visually and accurately reading out the detected liquid depth. A working system could be determined rationally through continuous detection of pressure and temperature changes in gas lifting.
