Abstract
The utility model relates to an oil log gas sample collection anti-freezing and anti-plugging protector, which is a protector with an anti-freezing function for continuously collecting gas in wellhead mud through a mud degasser and a sample gas pump and preventing water and mud from entering a gas sampling pipeline. The oil log gas sample collection anti-freezing and anti-plugging protector comprises a tank body, a heat insulation sealing cover, a sample gas inlet pipe and a sample gas outlet pipe. The oil log gas sample collection anti-freezing and anti-plugging protector is characterized in that the tank body has a double-layer structure of an interlayer provided with an internal wall and an external wall; an opening of the tank body is sealed by using the heat insulation sealing cover; the sample gas inlet pipe and the sample gas outlet pipe penetrate out of the heat insulation sealing cover to communicate the inside of the tank with the outside of the tank; and an anti-plugging suspended ball is connected to the lower end of the sample gas outlet pipe in the tank body through a limiting steel wire. The tank body of the protector is made of a corrosion-resistant and aging-resistant material, and the interlayer is vacuum or filled with a heat insulation material; the anti-plugging suspended ball is a solid or hollow sphere made of light material; and the protector has simple structure, and is easy to mount and maintain.
Description
Technical field
The utility model relates to a kind of oil log sample gas and gathers the anti-freezing anti-blocking protective device; be a kind ofly to collect gas in the well head mud continuously by mud degasser, sample air pump; prevent that mud from entering the gas production pipeline and having a kind of protective device of antifreeze function, belongs to the wellhead sample sampling instrument in the oil log engineering.
Background technology
At present; in the petroleum exploration and development drilling-log process of usefulness; it is a kind of column suspension plug formula anti-blocking-up protection apparatus that sample gas is gathered anti-blocking-up protection apparatus; there is following technology drawback in this device in practical application at present; as shown in Figure 2; this crust of the device is a column type; make with transparent organic material; cold in the open air; high temperature; exposure in sunshine; under the chemical erosion; aging rapidly in short time; the gas leakage of very easily breaking, in addition, this device has preferably polarization for suspension is moved down beyond the Great Wall; the plug periphery that suspends is generally less than 0.8mm with column type outer casing inner wall movement clearance; suspension plug formula antiplugging device is under the outdoor environment that freezes winter like this, because the well head sample air humidity degree of gathering by suspension plug formula antiplugging device is all above 80%, so the globule that condenses on the peripheral and column type outer casing inner wall at cold environment low suspension plug; at any time the plug that suspends can be frozen together with the column type outer casing inner wall; make the antiplugging device disabler of suspension plug formula antiplugging device, cause water; mud etc. enter adopts gas transmission line, damages follow-up checkout equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of oil log sample gas to gather the anti-freezing anti-blocking protective device; pass through structure design; the utility model can play and prevent freezingly, plays anti-sealing, mud etc. again and enters the effect of adopting gas transmission line, has avoided the infringement of checkout equipment.
The utility model adopts following technical scheme: a kind of oil log sample gas is gathered the anti-freezing anti-blocking protective device; constitute by tank body and thermal-insulating sealing lid, sample gas air inlet pipe, sample gas escape pipe; it is characterized in that tank body is the double-decker with interlayer interlayer of inner and outer wall; the tank body opening part is with the thermal-insulating sealing cap seal; sample gas air inlet pipe and sample gas escape pipe pass the thermal-insulating sealing lid and will be communicated with in the jar and outside the jar, and anti-blocking suspension ball is connected sample gas escape pipe lower end in the tank body by spacing steel wire.
Tank body of the present utility model becomes the double-layer heat insulation shell structure with anticorrosive, ageing-resistant material such as metal, glass fiber reinforced plastic, tempered glass material.Its double-deck interlayer interlayer is vacuum or fill insulant material.
Anti-blocking suspension ball of the present utility model is proportion<0.8g/cm
3The solid or hollow ball made of light material.
Anti-blocking suspension ball of the present utility model by three each other the spacing steel wire of 120 ° of angles be connected sample gas escape pipe lower end in the tank body.
During work of the present utility model, the sample gas of gathering covers by thermal-insulating sealing from sample gas air inlet pipe, enter in the antiplugging device device tank body, the saturated vapor in the sample gas sinks in the inner segregation junction of antiplugging device jar, and sample gas is walked around anti-blocking suspension ball by entering the output of sample gas escape pipe; When the sample gas that takes place to gather is sneaked into a large amount of liquid waters or mud; the liquid level of deposition raises in jar; the suspension ball is held up by buoyancy; push spacing steel wire; sample gas gas outlet in the suspension ball shelters from antiplugging device device tank body fully; play protection subsequent detection instrument, avoid the into generation of water, obstruction infringement.
The utility model is in the open air under cold, high temperature, the exposure in sunshine, is difficult for the aging gas leakage of breaking in long-time; And winter, the antiplugging device function can not lose efficacy under outdoor environment, and simple in structure, be easy to installation and maintenance.
