石油钻井方面的英文文章 求翻译

Perforation. Because of high reservoir pressure and insufficient formation strength, the well was perforated in heavy brine with 41/2-in. tubing-conveyed perforating guns oriented high side in a 350/10° phasing to prevent sand production. Deep-penetrating low-debris steel charges (4 shots/ft) were used. The dynamic-underbalance gun concept was used, with the atmospheric pressure inside the guns creating an instantaneous underbalance at the moment of perforation, removing the crushed zone from the perforation tunnels. A flow restrictor was spaced out inside the 7-in. liner to optimize perforation tunnel cleanout by use of the pore pressure before the wellbore returned to an overbalanced state.
DIACS Completion Installation. Oil producers on Visund have been completed as 7-in. monobore completions with downhole pressure and temperature monitoring. This reservoir was more complex than expected, and recent technology enabled monitoring and controlling the production. To optimize production, DIACS well completion, which enables selective production from different reservoir zones, was considered. The reservoir sections are separated with zone-isolation packers, and the production is controlled by monitoring pressure and temperature gauges in each zone with hydraulic operation of the flow-control valves installed in the respective zones. Each zone also contains a mechanical sliding sleeve in case the hydraulic control lines should fail. The objective of this well was to establish selective production from the three different reservoir zones:Tarbert, Etive/Ness, and Rannoch.
A total of five control lines, including three braided bumper wires, was run in hole clamped to the completion string.During installation of the horizontal subsea tree, a blowout-preventer (BOP) tubing-cutting test was performed at surface to ensure the drilling BOP’s controlline cutting capability. The completion operations were performed without use of a workover system. Packer fluid was reverse circulated into the production annulus and tubing before the upper hydraulically operated flow-control valve was closed and inflow tested, then all the packers were set simultaneously.
The well was tested with an oil rate of 3900 m3/d and will be produced at a rate of 2500 m3/d with production from all zones. Initially, zones A, B, and C have productivity indices as of 4.5, 91, and 635 m3/d/bar,respectively. Production from Zone A would not have been possible without a controlled production from the other zones, adding value to the DIACScompletion design.

Answer 1

穿孔。由于水库高的压力和不足，形成力量，以及穿孔的是沉重的卤水与41/2-in 。油管，转达了射孔枪面向高边坡在逐步一十零分之三百五十○ ° ，以防止沙子生产。深穿透低收费钢铁碎片（ 4球/英尺）的使用。动态欠枪使用的概念是，随着大气压力枪内创造一个瞬时欠此刻的穿孔，消除了碎石区，穿孔隧道。节流的流动是境内间隔7中。班轮优化射孔隧道清洗用的孔隙水压力面前的井筒返回一个overbalanced状态。
DIACS完成安装。石油生产国的Visund已完成7中。 monobore落成与井下压力和温度监测。这个水库是比预期的更为复杂，和最近的技术使监测和控制生产。为了优化生产， DIACS完井，使选择性生产从不同的水库区，进行了审议。水库部分分离区隔离包装，生产控制，监测温度和压力传感器在每个区，液压操作流量控制阀安装在各自的区。每个区还包含一个机械滑动的情况下套筒液压控制线应失败。的目的以及是要建立选择性生产从三个不同的水库区：塔伯特埃蒂夫/尼斯，并兰诺赫。

共有5个控制线，其中包括3名编织保险杠电线，是运行在固定孔完成string.During安装横向海底树，一个井喷，防（国际收支）油管切割试验是在地面完成，以确保钻井国际收支的controlline切割能力。完成操作不使用作业系统。派克流体扭转分发到生产环和前油管上液压流量控制阀被关闭，流入测试，然后所有的包装被同时进行。

该井测试与石油率三九零零立方米/ d和将制作的速度在2500立方米/ D与生产的所有地区。起初，区有A ， B ，和C生产力指数为4.5 ， 91 ，和635 m3/d/bar分别。生产从A区就不可能没有控制生产从其他区，增加附加价值， DIACScompletion设计。

穿孔。因为较高的储层压力和不足,也形成了强度和孔在沉重的盐水41/2-in. tubing-conveyed射孔枪在一个面向高端350/10°分期防止砂。Deep-penetrating low-debris钢费用(4球/英尺)。用枪的概念,dynamic-underbalance与大气压力的枪支创建一个瞬间欠平衡此刻的穿孔,消除压区从穿孔隧道。一个流动的节流棒是失神了一下里面的衬垫来优化穿孔7-in.隧道清洗用孔隙压力之前回到了井筒超值的状态。
DIACS完成安装。石油生产国已完成对Visund monobore 7-in.全澳的压力和温度监测和井下。这个水库是更复杂的比预期的要长,和最近的技术使得监控生产。以优化生产,DIACS井,使得选择性生产不同油藏区,被认为是。这个水库部分分开,并与zone-isolation包装生产控制是通过监测仪表的压力和温度和水力运行各区域的流体控制阀门安装在各自的区域。每个区域也包含了一个机械滑动套筒以防液压控制线路会失败的。本文的目的是要建立选择性生产井的三种不同油藏区:Tarbert Etive /,,Rannoch。
共有五个控制线路,包括三种编织保险杠电线、运行夹来完成string.During洞的水下卧式安装的树,防喷器)tubing-cutting blowout-preventer(表面进行试验,确保controlline钻井防喷器的加工能力。完成手术没有使用的修井系统。反循环封隔液是生产环上液压油管之前,操作阀门的流量控制,流入的行囊,然后进行设置。
测试的油率和3900立方米/年,就会产生的2500立方米/ d生产从所有的区域。最初,带A,B和C有生产力指数为4.5,91、635立方米/ d /酒吧。一个生产从本来就不太可能没有控制生产从其他区域,创造价值DIACScompletion设计。
