Description
Technical field
The utility model belongs to oilfield logging device technical field, is specifically related to a kind of oil field horizontal production well section water content in crude oil on-line computing model.
Background technology
The method of the crude oil water containing of downhole production test both at home and abroad at present, be the electrical conductivity measuring liquid with capacitance method or inductance method, its electrical conductivity of the change of the water content of sensor surface contact liq changes thereupon.Flow string crude oil is uneven with mixing of water, with current collecting umbrella, sleeve pipe need be produced liquid manifold to improve when certainty of measurement is measured, afflux liquid is flow through from sensor, certainty of measurement can reach 5%, test technology removes instrument with cable car, vertically go into the well by instruments weight, adjunction weighted lever is wanted in the tester bottom that test borehole pressure is greater than 10Mpa.
Be used for the production fluid trend of each producing well section of indirect analysis at present by net horizontal section temperature and pressure monitoring materials, true Liquid output and the water content of horizontal well each producing well section can't be determined.Horizontal well producing well section segmentation Liquid output water content in crude oil on-line monitoring problem is that horizontal wells technology is badly in need of the agricultural technology problem of solution both at home and abroad at present.
Utility model content
The technical problem that the utility model solves: design a kind of oil field horizontal production well section water content in crude oil on-line computing model, applied microwave measures moisture method, solves horizontal well production technological level production section water content in crude oil on-line real time monitoring problem.
The technical solution of the utility model: a kind of oil field horizontal production well section water content in crude oil on-line computing model, comprise sensor shield, described sensor shield is built with microwave remote sensor, and front end is connected with guider in well, and rear end is provided with test cable seal nipple; Described sensor shield is polymeric seal cover.
Described test cable seal nipple is three-core cable seal nipple.
Described three-core cable seal nipple is connected with three core test cables of continuous steel pipe armouring.
The utility model applied microwave measures moisture method, solves horizontal well production technological level production section water content in crude oil on-line real time monitoring problem.In addition, the utility model adopts the test cable of continuous steel pipe armouring, and when test borehole pressure is greater than 10Mpa, tester bottom need not adjunction weighted lever, simplifies logging technique, reduces logging cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Fig. 1, a kind of embodiment of the present utility model is described.
A kind of oil field horizontal production well section water content in crude oil on-line computing model, comprise sensor shield 3, described sensor shield 3 is built with microwave remote sensor 4, and front end is connected with guider 5 in well, and rear end is provided with test cable seal nipple 2; Described sensor shield 3 is polymeric seal cover, prevents micro-wave screening.Described test cable seal nipple 2 is three-core cable seal nipple.Described three-core cable seal nipple is connected with three core test cables 1 of continuous steel pipe armouring.Wherein two power lines are that microwave remote sensor 4 is powered, and a holding wire is for exporting the survey data of microwave remote sensor 4.
The utility model applied microwave principle, for the character of the special frequency channel microwave susceptible of water, achieves the measurement of moisture in mixing material.Achieve the measurement of sensor non-contact liquid moisture, crude oil water content measurement category 0-100%, certainty of measurement reach 0.5%.The crude oil water containing method under current capacitance method or inductance method measuring well of solving cannot the problem of afflux at horizontal well, achieves the measurement of horizontal well production casing cross section water content in crude oil.The foundation of microwave measurement crude oil water content is that profit dielectric constant difference is larger.The oil water mixture dielectric constant difference that moisture content is different is thus also different to the absorption of microwave signal.According to through the microwave signal size after oil water mixture and phase shift, measure the moisture content of oil water mixture.During use, by test cable downhole device, the utility model is pushed down-hole horizontal section and carry out water content in crude oil on-line monitoring, after completing test job, propose test cable.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalent variations done with content described in the utility model claim, all should be included within the utility model right.
