Problems solved by technology

The reality is that in order to save costs, small coalbed methane companies do not form their own professional maintenance teams. When workover operations are required, they will find maintenance teams again, which may delay production; There are many equipment failures, and there are fewer personnel with fewer professional qualifications

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, a coalbed methane, oil and gas downhole pipe string lifting equipment includes a support frame, on which an upper horizontal support 14, a middle horizontal support 15 and a lower horizontal support 16 are sequentially arranged from top to bottom. The support 14 is provided with an upper through hole 7 for passing through the sucker rod or the oil pipe, and on the upper horizontal support 14 is fixed an upper non-contact distance measuring sensor 10 which is arranged opposite to the upward through hole 7; in the middle horizontal support 15 The middle through hole 5 for passing through the sucker rod or the oil pipe is arranged on the top, and the middle non-contact distance measuring sensor 6 which is arranged in the middle through hole 5 is fixed on the middle horizontal support 15; There is a lower through hole 1 for passing throug...

Abstract

The invention discloses coal bed gas and oil gas down-hole string lifting equipment. The coal bed gas and oil gas down-hole string lifting equipment comprises a supporting frame body, wherein an upperhorizontal support, a middle horizontal support and a lower horizontal support are sequentially arranged on the supporting frame body from top to bottom; an upper non-contact type distance measuringsensor which is arranged towards the inside of an upper through hole is fixed on the upper horizontal support; a middle non-contact type distance measuring sensor which is arranged towards the insideof a middle through hole is fixed on the middle horizontal support; a lower through hole for a sucker rod or an oil tube to penetrate through is formed in the lower horizontal support; a lower non-contact type distance measuring sensor which is arranged towards the inside of the lower through hole is fixed on the lower horizontal support; and a clamping and lifting device is connected between theupper horizontal support and the middle horizontal support in a left-right sliding manner, and a clamping and lifting device is also connected between the middle horizontal support and the lower horizontal support in a left-right sliding manner. A down-hole string is clamped circularly by two crawler type lifting mechanisms which cooperate with each other, and thus, original large hoisting equipment with complicated structure for a conventional oil gas well is omitted.

Description

technical field [0001] The invention belongs to the technical field of coalbed methane and oil and gas development, and in particular relates to a coalbed methane and oil and gas downhole pipe string lifting equipment. Background technique [0002] Coal bed methane is a combustible gas whose main component is methane. It is usually adsorbed on the surface of coal particles, free in coal pores and dissolved in coal seam water, and is an accompanying product of coal. my country's coalbed methane reserves are very rich, ranking third in the world, with huge development potential. Coalbed methane is a kind of clean energy. Under the current general trend of environmental protection and the pressure of coal mining safety, it is imperative to vigorously develop coalbed methane resources. [0003] At present, in the field of coalbed methane surface mining, conventional oil and gas field mining supporting equipment is generally used for drainage, overhaul, maintenance, etc. Compare...
