The invention provides an electronically controlled steam distribution valve, which includes a working cylinder (1), the inner wall of the working cylinder (1) is provided with an inner flow hole (11), and the outer wall of the working cylinder (1) is provided with a steam distribution hole ( 12), the working cylinder (1) is provided with an adjustment assembly (4), the adjustment assembly (4) can adjust the flow rate of the fluid flowing from the inner flow hole (11) to the steam distribution hole (12), and the electronically controlled steam distribution valve It also includes an electric assembly (2) for driving the adjustment assembly (4). The ground-adjustable stratified steam injection pipe string contains the above-mentioned electronically controlled steam distribution valve. The electronically controlled steam distribution valve and the adjustable stratified steam injection pipe string can operate the underground steam distribution device on the ground by means of electric signal control, avoiding the problem of fishing, improving the condition of steam injection in the wellbore, and greatly improving Steam injection effect.
Description
technical field [0001] The invention relates to the field of heavy oil steam flooding, in particular to an electronically controlled steam distribution valve capable of adjusting the steam distribution volume through cable transmission signals on the ground. Background technique [0002] In the process of heavy oil steam flooding, considering factors such as the depositional state of the sandstone formation, it is necessary to perform steam injection in layers, and use different intensities of steam distribution between different layers to achieve the purpose of uniform production of the reservoir. The eccentric steam distribution valve in the commonly used eccentric steam distribution pipe string at present needs to fish the steam distribution nozzle because of changing the steam distribution parameters, and the success rate of this operation is extremely low, which greatly reduces the application of this technology and promotion prospects.
