复杂井测试施工方案分析

Well Test Implementation Project Analysis for the Well with Complex Condition

以渤海油田CFD18－2E－1井为实例，介绍了该井的测试状况、造成测试结果不真实的原因及下入套管和隔缝管后造成失败的原因，针对该井复杂井况介绍了取得测试成功的具体测试施工方法；同时对该井未下入隔缝管之前的测试结果不能反映地层真实产能的原因、下入隔缝管的必要性和忽略的因素、下入隔缝管后影响测试的因素及隔缝管堵塞不能解堵的原因进行了详细的分析。提出了对该井应该采取的正确测试方法、工艺步骤和完善的下入隔缝管方案。

Taking CFD 18-2E-1 well in Bohai oil field as an example,We introduced the well test case,fail reasons and developed,an new successful test implementation method,We analyzed why without the real productivity for the formation,The nessary for locating the slotted liner and the effect factor which can be neglect are also analyzed.the right test method,implement steps and locating slotted liner steps are given in this paper.
