Description
Technical field:
The utility model relates to a kind of downhole hardware that is used for the oil well delamination test.
Background technology:
At present, the formation testing in oil field development, the oil well production process is still counted the master with mechanical compression.Because normally used pressure gauge precision is lower, it is inaccurate when clock is walked, and Test Switchboard is by operation manually, not only can not guarantee the accurate of time, and operate not in place sometimes, construction once can only be tested a well section, can only carry out fluid sampling to whole production well section, thereby can't judge the variation of interior each producing zone position liquid measure of whole pit shaft and fluidity.Want to obtain the formation parameter of each layer position, implement fluidity, just must once test separately each substratum, cause cost of production to improve greatly, oil mining effect and economic benefit are affected.
The utility model content:
The purpose of this utility model is to provide a kind of multicore cable oil well delamination testing well lower device that is used for the oil well delamination test.
The utility model is to realize like this.This kind downhole hardware is made up of single-core cable, multicore cable, oil pipe, downhole testing instrument, a plurality of valve control device and a packer, downhole testing instrument and the combination of first floor position valve control device are arranged in the shared urceolus, upper and lower end connects respectively on oil pipe, downhole testing instrument upper and lower end is connected with the multicore cable that connects down with the single-core cable that ground testing system is connected with the top respectively, and tipping has first order packer on the oil pipe of the shared urceolus of downhole testing instrument and first floor position valve control device below; On the oil pipe of first order packer below successively tipping have second, third and with the corresponding valve control device in zonal testing layer position, join by multicore cable between each valve control device, every cable core connects a valve control device, and tipping has and is used for the packer of sealing layer position on the oil pipe therebetween.Oil well underground work when construction, with this device with down-hole oil tube by the purpose payzone in the oil well casing under the designing requirement after, discharge packer each payzone separated.During test, the instruction that the ground test control system is sent is sent to the downhole testing instrument on this downhole hardware top by single-core cable, tester is according to instructing each cable core by multicore cable to be transferred to each valve control device respectively, open or close any one valve by it, and test result is sent to ground system.
The utility model is novel, and is reasonable in design, and the reliability height utilizes it to record a plurality of parameters of layering by the shared downhole testing instrument in multilayer position under the situation that once plays lower tubular column, provides the measure foundation for improving the oil mining effect.
Description of drawings:
Fig. 1 is the assembling annexation schematic diagram of the utility model in pit shaft.Fig. 2 is the structural representation of this device downhole testing instrument and valve control device combination.Fig. 3 is the circuit block diagram of this device.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made up of oil pipe 1, single-core cable 2, downhole testing instrument 3, valve control device 4, multicore cable 5, packer 6, its assembling, annexation are as follows: downhole testing instrument 3 is arranged in the shared urceolus with 4 combinations of first floor position valve control device, upper and lower end connects respectively on oil pipe 1, downhole testing instrument 3 upper and lower ends respectively with on the single-core cable 2 that connects be connected with the multicore cable 5 that connects down, being hinged with on downhole testing instrument 3 and the first floor position valve control device 4 common urceolus below oil pipes has first order packer 6; On the oil pipe 1 of first order packer 6 belows successively the tipping have second, third and with the corresponding valve control device 4 in zonal testing layer position, be connected by multicore cable 5 between each valve control device 4, every cable core connects a valve control device 4, and tipping has and is used for the packer 6 of sealing layer position on the oil pipe therebetween.The structure of this device downhole testing instrument 3 and valve control device 4 parts as shown in Figure 2, the two is co-located in the same urceolus 8, be provided with motor reducer 15 in tester 3 inner cores 18, direct current generator 16, test and control circuit board 17, temperature, pressure and other parameter sensors 19, the upper end is stretched out by drive link 14, drive link 14 is connected with control valve 13, the upper end is connected with top connection 9, tester 3 inner cores 18 lower ends are connected with lower contact 20, on, lower contact 9,20 respectively with cable head 7,21 are connected, among the figure, label " 10 " is a sealing ring, " 11 ", " 12 " are respectively tester and control valve inlet, and " 22 " are fluid cavity.During work, single core cable enters instrument internal by cable head 7, the rotation direction of direct current generator 16 is controlled in the instruction that test and control circuit 17 transmit according to ground, motor 16 drives motor reducer 15 and rotates, drive control valve 13 rotations by drive link 14, control valve 13 is a loop configuration, and control valve inlet 12 is communicated with fluid cavity 22.By the rotation of control valve 13, when control valve inlet 12 was communicated with tester inlet 11, the instrument outside liquid just can enter in the fluid cavity 22.Have via hole to be used for passing through of lead in the middle of the drive link 14, sealing ring 10 is used for electrical appliance part and is isolated from the outside.
