Description

Technical Field

[0001] The present invention belongs to the technical field of stratified oil production, and particularly relates to a downhole production and water distribution device and method with multi-control by one machine. Background Art

[0002] At present, the production distributors / water distributors used in oil fields are all one production distributor / water distributor corresponding to one reservoir, that is, each production distributor / water distributor can only control one interval. If stratified oil production (water injection) is required, each interval needs to be equipped with a production distributor / water distributor. This not only increases the process cost but also brings certain difficulties to production adjustment (injection allocation) control. Especially in the artificial lift stratified oil production process, due to the use of pumping equipment (screw pump, electric submersible pump, hydraulic pump, etc.) in the process, the downhole production distributor cannot cross the pumping equipment to adjust the production, and it is even more impossible to adjust the production layer by layer for multiple intervals.

[0003] At present, the method for artificial lift oil wells that require stratified oil production is to adopt the plugging pumping (or plugging) process, that is, first lower the plugging pumping (or plugging) string to block the reservoir that needs to control the production, and then lower the pumping equipment to produce the non-controlled reservoir. That is, the stratified production string is separated from the pumping equipment. In this way, two completion strings need to be lowered during on-site construction, and at the same time, it is impossible to adjust the reservoir that needs production adjustment during the production process.

[0004] After investigation, the existing technologies have the following problems:

[0005] 1) The stratified production string needs to be separated from the pumping equipment (string release);

[0006] 2) The stratified production (water injection) string needs to be equipped with production distributors / water distributors layer by layer;

A method for underground production and water distribution with one machine and multiple controls, used for the underground production and water distribution device with one machine and multiple controls according to any one of claims 1 to 9, characterized in that: The following steps are involved: Connect the one-machine-multiple-control downhole production and water distributor to the artificial lift pumping equipment and lower it into the well together with multiple packers; The packers of each layer are set and the wellbore is divided into multiple sections by the packers; A control instruction is sent from the ground according to a pre-set production program, and the control instruction is transmitted to a control module circuit board (5). The control module circuit board (5) decodes the control instruction and sends it to a switch regulating valve group at a corresponding layer. The switch regulating valve group opens or closes the gate valve according to the control instruction, or opens the gate valve according to a specified opening degree; the artificial lift pumping equipment extracts liquid from the corresponding reservoir; The oil production center channel pressure sensor (230), the first flow channel pressure sensor (231), the second flow channel pressure sensor (232), and the third flow channel pressure sensor (233) respectively monitor the pressures of the oil production center channel (1), the first flow channel (2), the second flow channel (14), and the third flow channel (17) according to pre-settings and transmit the monitoring data to the control module circuit board (5) in real time. The control module circuit board (5) then transmits the data to the ground through the control signal line (22); An adjustment control instruction is sent from the ground, and the control instruction is transmitted to a control module circuit board (5). The control module circuit board (5) decodes the control instruction and sends it to a switch regulating valve group at a corresponding layer. The switch regulating valve group opens or closes the gate valve according to the instruction, or opens the gate valve according to a specified opening degree.
