The invention discloses a device for generating electricity by using petroleum exploitation formation pressure energy and transportation residual pressure energy. The device comprises a device for generating electricity by using formation pressure energy, and a device for generating electricity by using residual pressure energy, wherein the device for generating electricity by using the formation pressure energy includes a one-inlet double-outlet type rotating speed tuning valve and speed control linkage actuation mechanism, a filter separation buffer, a multi-head spiral plate centrifugal impeller rotor type gas-liquid phase turbine, a high-back-pressure natural gas turbine and two generators; and the device for generating electricity by using the residual pressure energy includes a piston type single-stroke natural pneumatic unit and a piston type two-stroke natural pneumatic unit connected to a high-pressure exhaust port of a superior station side by side. The device can use the pressure energy, released from the formation in the petroleum natural gas exploitation process, and the residual pressure energy of transporting the natural gas to a gas collecting and transporting station, an inferior station, a branch station and a tail station for acting to generate electricity.
Description
technical field [0001] The invention relates to oil and gas exploitation, pipeline transportation and steam turbine power generation, in particular to a power generation device which utilizes formation pressure energy and converts formation pressure energy into mechanical energy in the process of exploiting underground oil and gas. Background technique [0002] At present, oil and gas exploration, oil and gas pipeline transportation, and steam turbine power generation have mature and perfect technologies in manufacturing, technology, operation, and automatic control. However, the technology for combining the three technologies with efficient utilization is still blank. The three technologies belong to the three fields of mining, pipeline transmission, and power generation, and are in a state of being alone in charge of each. The field of oil and gas is not only a large consumer of electric energy, but also consumes and wastes the formation pressure energy in the process of o...
