关井

保证BOP上的阀门、压井管线、节流管线和节流管汇根据关井程序正确排列；

Ensure the valves on the BOP , kill lines , choke lines and choke manifold are correctly lined up according to the Shut-in Procedure .

通常是环形原点的式样。关井环形空间测试法

未知油藏参数（h、Φ、Ct）时，采用两次开井生产，两次关井测稳态井底压力或岩心生产端压力方法，可以计算出岩心和油藏的启动压力梯度。

If these reservoir parameters are unknown , adopting dual opening and closing in procedure to measure bottom hole stable pressure or pressure of producing end of core .

④在流程管汇与井口之间设置了ESD紧急关闭阀，可实现瞬时关井。

Fourth , ESD emergency shut-down valve is set between manifold and well head , which can be used for instant shut in .

目前注水开发油田矿场确定单井控制的平均地层压力真值不仅关井时间较长（长于2d），而且误差较大。

The procedure to obtain the average reservoir pressure controlled by a single well used currently in oil fields developed under water flooding is time consuming ( longer than 2d ), and relatively larger error often occurs .

纤维的加入提高了防砂体的早期抗压强度（即固化12~24h时的抗压强度），作业占井周期由原来的关井4d缩短为2d；

The added fibres strengthened the early compressive strength ( the com-pressive strength when curing for 12-24h ) , and operation period reduced from four days of shut in to two days .

在此基础上，考虑现场条件，统计大港油田35口井实测资料，提出关井时间可由流动系数确定：流动系数大于1μm2·m／（mPa·s）为5～8h；

Actually measured data in 35 wells were gathered statistically and on this base it is suggested that when flow coefficient is larger than 1 μ m 2 · m / ( mPa · s ), well shut in time will be 5 8h ;

为改变目前LPR压控测试阀在开、关井过程中需要保压的局限性，研发了一种适应我国油田特点的新型全通径压控测试阀。

To change the limit of LPR test valve which need annulus pressure to keep static in opening period , a new model pressure controlled full bore testing valve which is applied for our oilfields ' features is developed .

M25井首次应用该工艺取得成功，在对上层抽汲求产的同时，对下层关井恢复，并可对作业全过程进行实时监控。

The first time of applying this tech in M25 well is successful for swabbing and obtaining production to upper layer and acquiring build-up pressure data by closing well and monitoring all operation process on real time .
