Abstract
An intersecting type sampler for an oil sample of an oil well comprises an oil input pipe, a by-pass pipe, a sampling section, an oil input ball valve, an oil output ball valve, a sampling ball valve, an air bleed ball valve and a check ball valve. The check ball valve is arranged in the middle of the oil input pipe, and a by-pass pipe parallel to the oil input pipe is arranged between the upper end and the lower end of the oil input pipe. The sampling section is arranged in the middle of the by-pass pipe, the ball valves in parallel connection with the by-pass pipe are arranged at the two ends of the sampling section respectively, the oil input ball valve is arranged on the left side, the oil output ball valve is arranged on the right side, the air bleed ball valve with a diameter of 25mm is arranged on the upper wall in the middle of the sampling section, the sampling ball valve with the diameter of 25mm is arranged on the lower wall, the oil input pipe is horizontally connected with an oil input pipe of a metering station separator, and the by-pass pipe is arranged at the upper position. According to the intersecting type sampler for the oil sample of the oil well, by means of the method of intersecting the section of oil flow in the pipe, the problem that the sampled oil sample contains more water or less water and does not present the true water content of crude oil produced by the oil well is solved, and conditions are created for obtaining a true oil sample and real water containing data of the crude oil.
Description
Technical field
The utility model relates to a kind of oil well oil sample interception type sampler, solves the problem of reasonable sampling.
Background technology
At present, oilfield sampling is all to sample on the standpipe of well mouth of oil well back-pressure valve top flowline.Sampling mode is probe tube level to be injected to 1/4th places of flowline riser internal diameter, probe tube import department is provided with an elbow, make elbow entrance vertically upward, directly to carrying out oily direction, at the probe tube other end, establish a sample valve, control sampling, this sampling method is slightly truer than the probe tube sample contained oil water yield that sampling method of slotting formula takes out, but because the water in the profit stream in standpipe is at tube hub, oil gas is adjacent to tube wall, the sample or the oily water on the high side that take out are on the low side, can not represent the true moisture situation of crude oil, mislead to the production system of formulating oil well.
Summary of the invention
The purpose of this utility model is to provide a kind of oil well oil sample interception type sampler, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises oil inlet pipe, bypass pipe, sampling section, fuel inlet ball check valve, fuel-displaced ball valve, Sampling ball valve, venting ball valve and cut-off ball valve, it is characterized in that oil inlet pipe middle part is provided with a cut-off ball valve, at oil inlet pipe, between two ends, be provided with up and down a bypass pipe parallel with oil inlet pipe, the middle part of bypass pipe is provided with sampling section, two ends in sampling section are provided with one and bypass pipe ball valve connected horizontally separately, the left side is fuel inlet ball check valve, the right is fuel-displaced ball valve, supermedial upper wall in sampling section is provided with the venting ball valve that a diameter is 25mm, be provided with below the Sampling ball valve that a diameter is 25mm, the oil inlet pipe level connection joint of oil inlet pipe and measuring station eliminator, makes bypass pipe upper.
The diameter of oil inlet pipe, bypass pipe and the diameter of sampling section and the oil inlet pipe of metering separator is made as same footpath, and diameter is 80mm.
The utility model is by the sampling method of one section of oil stream in interception tube, avoided the moisture many or moisture few true moisture problem of crude oil that does not represent oil well production of oil sample of getting, and for obtaining true oil sample, obtains true moisture data and created condition.
Accompanying drawing explanation
Fig. 1-structural representation of the present utility model;
1-oil inlet pipe in figure; 2-bypass pipe; 3-fuel inlet ball check valve; The 4-ball valve of exitting; 5-Sampling ball valve; 6 fuel-displaced ball valves; 7-ends ball valve.
The specific embodiment
For further disclosing the technical solution of the utility model, below in conjunction with Figure of description, by embodiment, elaborate:
The utility model comprises oil inlet pipe 1, bypass pipe 2, sampling section, fuel inlet ball check valve 3, fuel-displaced ball valve 6, Sampling ball valve 5, venting ball valve 4 and cut-off ball valve 7.It is characterized in that oil inlet pipe middle part is provided with a cut-off ball valve 7, at oil inlet pipe, between two ends, be provided with up and down a bypass pipe parallel with oil inlet pipe 2, the middle part of bypass pipe 2 is provided with sampling section, two ends in sampling section are provided with one and bypass pipe ball valve connected horizontally separately, the left side is fuel inlet ball check valve 3, the right is fuel-displaced ball valve 6, at the supermedial upper wall that samples section, is provided with the venting ball valve 4 that a diameter is 25mm, is provided with below the Sampling ball valve 5 that a diameter is 25mm; The oil inlet pipe level connection joint of oil inlet pipe and measuring station eliminator, makes bypass pipe 2 upper.
As will be got the oil sample of certain mouthful of oil well time, certain mouthful of well is imported to metering separator, now the cut-off ball valve 7 on oil inlet pipe 1 is closed, fuel inlet ball check valve 3 and fuel-displaced ball valve 6 on bypass pipe 2 are opened, venting ball valve 4 and Sampling ball valve 5 are closed, certain oil well is next oily enters eliminator from bypass pipe, after separation, from eliminator flowline, out enters gathering line.Deng certain oil well enter the oil stream of eliminator stable after, shut fast fuel-displaced ball valve 6 and fuel inlet ball check valve 3, open fast cut-off ball valve, certain well crude oil enters eliminator from oil inlet pipe 1, normally through eliminator, enters gathering line.Now opening the following Sampling ball valve 5 of sampling section starts to draw oil sample, when the oil of sampling section is got while finishing soon, open venting ball valve, make sampling section internal and external pressure balance, allow the interior oil of sampling section all flow out, sampling end, shut venting ball valve 4 and Sampling ball valve 5, open fuel inlet ball check valve 3 and fuel-displaced ball valve 6, shut cut-off ball valve 7, the output oil of certain oil well normally goes rancid from eliminator.If get a plurality of oil samples, mix the moisture average of chemical examination, can get several oil samples more by aforesaid operations step, if get the oil sample of other oil wells in addition, by above-mentioned operating procedure, draw oil sample.
