如果需要经第二井口进入井系统,例如如果需要在支管11内进行管理操作或其它操作,则可以将卷筒19和润滑器20装在第二井口2的顶点上,从而将工具降入到井系统中。 If desired, for example if necessary to manage the operation or other operating system via the second wellhead into the well in the branch pipe 11, the roll 19 and can lubricator 20 mounted on the apex of the second wellhead 2, thereby lowering the tool into well system.

在这种情况下,可以经第一井口1用下部水平井口7和支井8、9进行生产。 In this case, a first wellhead 1 can be produced by the use of the lower horizontal branch wellbore and wellhead 7 8,9.

应当明白,工具17可以包含自身用的动力源和无线数据传输线路,而不用将动力源传送到工具17的和将数据来回输送的脐形缆18及其设备。 It should be appreciated that tool 17 may include its own power source and a wireless data transmission line, instead of transmitting the power source to the tool 17 and conveyed back and forth the data umbilical cable 18 and its equipment.

另外,可以通过永久嵌入井中的井管、钻井导管或导筒传送电磁波和将作为活动电气触点的电感耦合器装在工具17上,由此达到动力和/或数据的传送。 Further, the well can be permanently embedded in the well pipe, drilling or catheter guide tube and transmitting electromagnetic inductive coupler activity as electrical contacts mounted on the tool 17, thereby achieving a power transmission and / or data. 去掉脐形缆18可以省去卷筒19和润滑器20,在这种情况下,可利用井口1和2上的溜槽(未示出)将工具17下放到井系统中。 Removing the umbilical cable 18 may be omitted and the drum 19 lubricators 20, in this case, on the wellhead 21 and the chute (not shown) of the tool 17 lowered into the well system.

为避免应用脐形缆18和/或频繁地在井系统中插入和取出该工具17,井系统可具有若干井底区域(未示出)。 To avoid the application of umbilical cable 18 and / or frequent insertion and removal of the tool in the well system 17, the system may have a plurality of downhole well region (not shown). 这些井底区域是由这样的区域形成的,在此区域中,井孔或井孔中的生产导管具有放大的直径或侧面的腔,这种腔在不用工具17和/或其所载的设备时可用作它们的停靠站。 These regions are formed by the bottom of this region, in this region, wellbore or wellbore production lumen catheter having an enlarged diameter or side of the device without such a cavity in the tool 17 and / or contained when they are used as stops.

井底区域可以配有专用连接部件,以便与地面3进行动力连接和通信。 Bottom zone may be provided with a dedicated connection member, for the power connection and the communication with the ground 3. 如果工具17和设备用蓄电池供电,则蓄电池可以在井底的一个或多个区进行再充电。 If the tool 17 and battery-powered equipment, the battery can be recharged in one or more zones of the bottom. 如果工具17和/或设备包括传感器和贮存收集数据的存贮器,则可以在底部区域取出收集数据,并将该数据传送到地面上的数据处理设备。 If the tool 17 and / or sensor device comprises a memory and the storage of collected data, the data collected can be removed in the bottom region, and transmits the data to the data processing apparatus on the ground. 在这种情况下,运载工具17本身可以用作为一种穿梭运输工具,该工具可以在靠近底部区域的地方为永久安装的传感器或其它设备再装上蓄电池,并取出收集的数据,随后将这些数据发送到地面上。 In this case, the vehicle 17 itself may be used as a transport shuttle, the tool may be permanently installed sensors or other devices and then loaded on the area near the bottom of the battery, and remove the collected data, and then these transmitting data to the ground. 另外,工具本身的蓄电池也可以形成井底动力,以便用来例如设定阀或驱动钻井设备或其它设备。 Further, the tool itself may be formed of a battery power downhole, for example to set a valve or to drive a drilling device or other devices.

应用本发明的方法和井系统不限于具有两个井口1和2的井系统,在这种两个井口的井系统中,用一个井口2持续进行生产,而用另一个井口1进行管理操作。 A method and well system according to the present invention is applied is not limited to a well system with two wellheads 1 and 2, in which two well wellhead system, with a wellhead 2 continues production, and management operations with another wellhead 1. 井系统还可以包括三个或多个井口,而其中只有一个井口具有运载装置和滑槽装置,以便将设备下放到井系统中。 The well system may also comprise three or more wellheads, which only a wellhead having a carrier and a sliding means, so as to lower the device into the well system. 此井口可以位于例如海上平台的甲板上,作为将设备运载到井系统中和操作井下设备的专用进入点,而同时,在正常操作期间不用此进入点进行油或天然气的生产。 This wellhead may be located on a deck of an offshore platform, for example, carried into the device as well system and operation of downhole equipment dedicated entry point, while, during normal operation without this entry point of the oil or natural gas production. 这种井系统的其它井口可以位于海底,并向位于平台上的生产设备输送油或天然气。 Other wellhead system such wells may be located subsea, production equipment and positioned to convey oil or gas on the internet. 在这种情况下,化学试剂、蒸汽或其它注入流体可以通过设备进入点注射到井系统中,如果在平台上的处理装置偶然发生过载或出故障,则可使油和/或天然气通过设备进入点重新注入到井系统中。 In this case, chemical agents, steam or other injection fluids may be injected through the entry point in the well system device, if the processing means on the platform over occasional failure or an overload, it allows oil and / or gas through the apparatus into the point reinjected into the well system. 如果将工具17插入到海底的井口,则可以使用水下运输工具来实现这一点。 If the tool 17 is inserted into the subsea wellhead, you can use an underwater vehicle to achieve this.

还应当明白,可以分阶段开发井系统。 It should also be understood that the system can be phased development wells. 首先钻第二垂直井孔5和下部水平孔7,以这种方式开始开发附图所示的井系统。 By first drilling the second vertical wellbore 5 and the lower horizontal hole 7 in such a way to start developing a well system shown in the drawings.

根据钻出的孔5和7执行井底含油/气层的成像法,据此可以准确地将上部水平井孔和支井10和11钻到含油/气层。 The drilled holes 5 and 7 perform downhole oil / gas reservoir imaging method thus can accurately upper horizontal wellbore and the branch wellbore 10 and drill 11 oil / gas reservoir.

随后用第二井口2开始生产油和/或天然气,并收集准确的生产和含油/气层数据。 Followed by a second wellhead 2 starts producing oil and / or gas, and collecting accurate production and oil / gas reservoir data. 在计算这些数据以后,钻第一井孔4,并连接于水平井孔6和7,使这些部分构成垂直井孔4和5之间的可以移过设备的井下通道。 After the calculation of these data, drilling the first wellbore 4, and is connected to a horizontal wellbore 6 and 7, such that the parts formed between the vertical wellbore 4 and 5 can be moved through the channel of the device downhole.

然后钻出和完成支井8和9,进一步扩大井系统,同时用第二井口2继续进行油或天然气的生产。 Then drilled and completed wells 8 and support 9, further expansion of the well system, while the second wellhead 2 continues with the production of oil or gas.

在用井口1和2两个井口开始生产油或天然气之后,可以采用再进入钻井技术进一步扩大井系统,在这种技术中,可使设备经井口1或2的一个井口进入和移出,同时经另一井口1或2继续进行生产。 1 and 2 with two wellhead wellhead after the start of oil or natural gas production, drilling techniques may be employed to further expand re-enter the well system, in this technique, enables the device to the wellhead via a wellhead 1 or 2, into and out of, at the same time by another wellhead 1 or 2 continues production.

因此可以在任何时间除去制约生产的因素并优化井口的流动特性。 Thus production constraints can be removed at any time and to optimize the flow characteristics of the wellhead. 还可以增大开发的灵活性,方法是将具有多余垂直流动能力的一个井连接于其生产受垂直流动性制约的相邻井的工作面上。 May further increase the flexibility of the development, it is a shaft having a working surface perpendicular to the flow of excess production capacity is connected to its adjacent wells by the constraints of the vertical flow.

另外,井口不一定如附图所示是间隔开的。 Further, the wellhead is necessarily spaced apart as shown in the drawings. 井系统还可以包括在单个垂直井中的一对平行的或共轴的井管,该井管在井底通过井孔相互连接,该井孔构成一个封闭的环形,从垂直井开始到垂直井。 The well system may also comprise a single pair of parallel vertical well or well pipe coaxially, the risers at the bottom are interconnected by a wellbore, the wellbore to form a closed loop, starting from the vertical well to vertical wells. 在这种情况下,如果井具有共轴的井管,则一般希望用内管来传输运载工具和/或其设备,使其进、出井系统,而用包围的管或周围的若干管来生产油和/或天然气。 In this case, if the well has a wellbore tubular coaxial with the inner tube is generally desirable to transport vehicles and / or equipment, into and out of the well system, but with several tubes or pipes surround to produce oil and / or natural gas.
